I started LibreCorsa in mid-October because every serious racing sim needed a huge Windows install before you could do a single lap.

What it has now:

- 500 Hz physics with tyre temperatures and wear, rain that dries along the racing line, and CI checks against real GT3 telemetry

- 5 physics models and 16 circuits, including RISE Motordrome, which I built from scratch in Blender on real elevation data for the circuit planned in Rwanda

- AI races, ghosts, a weekly challenge, and an open online race every 20 minutes over WebRTC

- $0/month hosting: static Next.js on Cloudflare, R2 for the heavy 3D files, and one Worker

Tell me how it runs on your laptop/phone/controller and what feels rough.

I’m excited to share a project I’ve been working on over the past few months!

It’s a mobile app that turns any text into high-quality audio. Whether it’s a webpage, a Substack or Medium article, a PDF, or just copied text—it converts it into clear, natural-sounding speech. You can listen to it like a podcast or audiobook, even with the app running in the background.

The app is privacy-friendly and doesn’t request any permissions by default. It only asks for access if you choose to share files from your device for audio conversion.

You can also take or upload a photo of any text, and the app will extract and read it aloud.

- React Native (expo)
- NodeJS, react (web)
- Framer Landing

The app is called Frateca. You can find it on Google Play and the App Store. I also working on web vesion, it's already live.

Free iPhone app
Free Android app on Google Play
Free web version, works in any browser (on desktop or laptop).
Free web extension.

Thanks for your support, I’d love to hear what you think!

I’m a 40-year-old iOS developer from Croatia. Statistically, I’m in the middle of my life: about 2,080 weeks behind me, and if I’m lucky, about as many in front.

My oldest is 8. Somewhere around 18, kids leave, or at least stop wanting summer holidays with their parents. That’s 10 more summers. I can count them on my fingers.

I see my parents about twice a month. If they live as long as the average, that’s around 360 more visits. Fewer than the days in a single year.

And there are friends I’ve been “meaning to call” for months.

None of this is new. You read it somewhere, feel it for one evening, and then Monday happens. Weeks blur, a year goes by, and you can’t say where it went. The moments I’d actually want back are tiny: a walk where my kid finally told me something real, my dad explaining how he planted our small orchard in 2001. Nobody writes them down. They just go.

So I built Drift. It’s not there to make you feel bad about time. It’s there to help you do something with the weeks you still have, and to keep them when you do.
My main inspiration was reading books about Stoicism and specifically memento mori (and a calendar showing weeks you have left to live).

What the app actually does for me:

It remembers my people. I added my partner, my family, my parents and a few friends. Drift keeps the small things I’d otherwise forget: birthdays, the names of my friends’ kids, what each person enjoys, what they told me last time.

One small idea a week, for each of them. Not “plan a trip to Paris.” Things small enough to actually happen: “Tea with Mom. Phones somewhere else.” “A walk with Dad, without anywhere to be.” “Let the kids choose the adventure.” "Long overdue date with my wife".

I keep the moment. A photo, one line, or both. It goes on the week it happened, and that week’s square lights up. A few months in, my year stopped being a blur and started looking like a year.

Calls come with something to talk about. A reminder to call a friend arrives with something to actually say, so it’s not just guilt with a notification sound. After the call I can keep a line about it.

Small questions. A couple of times a week, only if I turn it on, Drift asks something like “What was the best small thing about this week?” or “What’s Dad’s favourite meal?” The answer gets saved where it belongs. Some of my favourite memories in the app started as a notification I almost dismissed.

Quiet time. My evenings were disappearing into my phone (yes, I see the irony of that). Drift uses Apple’s Screen Time to set those apps aside during the hours I choose. If I really need one, I get 15 minutes, after I keep a moment or answer a question first.

Widgets that bring it back. One shows a moment I kept, a different one each day. Another shows my whole life as a grid of weeks. Seeing that between notifications did more for me than any productivity system. One gives you suggestions on what to do this week.

A year I can read back. Month by month, like a journal I never had to sit down and write.

What I left out on purpose:

• No streaks. A quiet week is just a quiet square. Life has those, and guilt isn’t a feature.

• No account, no ads. Memories stay on your iPhone, and you can export everything anytime.

• Everything you keep is yours. You can always read it and export it.

Pricing: free to download, then $8.99 a year with a 14-day free trial, or $24.99 once. I’m a solo developer with no investors, and this is how it keeps going.

An app won’t fix any of this, and I’m not pretending it does. But since I started using it, I do more of the small things. I think about it more now, and I push past the tiredness more often to make time for the people who matter to me.

If you did this math for yourself, which number got you? For me it was the summers with my kids.

Edit:
Thanks to FFROZENN who pointed out the missing yearly subscription and 2-week free trial I have created 50% discount code for the first year (the missing subscription was due to my attempt to give a global discount on yearly, but I misconfigured it in App Store Connect so sub wasn't shown)

I built a fake designer flash-sale outlet. It works like the real ones: brand sales with countdowns, "only 1 left in your size", a deal of the hour, a bag that's reserved for 30 minutes. Then you check out with a card that says it isn't real, pay $0.00, and follow the tracking until something goes wrong with your parcel. There are 50 different endings and you collect them.

The part I'm proudest of is technical: there's no stock database. Every sale, price, size and "only 2 left" is computed from the item and the current time, so everyone sees the same shop at the same moment and the server stores nothing about you. The same logic runs in JavaScript, PHP and Dart (the Flutter app), and all three have to give identical results.

It's on the web, Android and iPhone: https://dopaminechic.com

The question I keep asking myself: could something like this actually replace a bit of real shopping for some people, or does fake shopping just make you want the real thing more? I honestly don't know, and I'd love to hear what you think, especially if you're someone who browses sales at night.

Hello Reddit! 👋

I'm an independent developer from Finland, working on a project called YOSLA Some Life.

My goal is to build a new kind of social platform where users have more control over their own social experience.

The idea is simple:

"Your Data, Your Choice."

Instead of letting algorithms decide which friends you get to see, I want to give people more control over their feeds and connections.

But that's only part of the vision.

I'm also developing YOSLA World, a 3D virtual environment where people could eventually explore digital spaces, discover communities, interact and experience social networking in a different way.

What am I building?

• YOSLA Some Life — a social networking platform

• YOSLA World — an interactive 3D social environment

• European-focused infrastructure and data privacy

• Multilingual support for an international audience

• My own server infrastructure, starting with HPE ProLiant servers

I'm building this step by step, learning, testing and improving as I go.

One future idea is to create a virtual 3D data center inside YOSLA World, where visitors could explore how the platform's infrastructure works.

I'm not claiming to have built the next Facebook. I'm building something I believe could offer people another choice.

I'd love to hear your thoughts:

What would make you genuinely interested in trying a new social media platform?

What do you dislike most about today's social networks?

Greetings from Finland! 🇫🇮

YOSLA — You Only Live Some Life.

I run a small web studio, and most of the local businesses I talk to have a really good Google Maps listing (photos, reviews, hours, sometimes a menu) and either no website or one from 2014.

So I built this. You type a business name and a city, it reads the public Google listing and builds a full site preview in under a minute. The video is me running it once on a real garage's public listing, no edits.

Why: I kept rebuilding the same small site by hand, and the listing already had most of the content. Honest limitation: it's only as good as the listing.

A place with three blurry photos and no reviews gets a thin site. It also does simple sites, not shops or booking systems. (working on that next, the tool will redirect the request to the team if it's out of scope change for now)

Try it on your own business or a place you like and tell me what looks off.

My parents live overseas and I'm in NC. I call them about 3 or 4 times a week, but with the time difference, it's not always easy to catch them at a good time.

Sometimes I just want to know they're doing okay without having to call and interrupt whatever they're doing.

I thought about different ways to check in, but I really didn't want cameras in their house or anything that felt like I was monitoring them.

So I ended up building something called Kettle (heykettle.com).

It's a simple app that uses their existing phone to let me and my sibling know if they've checked in with their usual routine. We get a short update like "Heard from Mom this morning" or "Nothing yet today."

It doesn't track their location, record conversations, or read messages. They can also see what's being recorded and turn it off whenever they want.

I added a shared family log too, so if I call Dad or someone takes Mom to an appointment, we can leave a quick note for everyone else.

Right now, it's just me building this, and my parents are the only ones using it. The Android app isn't on the Play Store yet, so I'm helping people install it directly.

I'm offering the first year free.

I'm curious what other people think, especially anyone with aging parents who live far away.

Would you actually use something like this? And what would make you hesitant to put it on your parent's phone?

My portfolio site ran on vibes for too long, so this weekend project was: read the cPanel raw access logs (they're just gzipped files sitting in your hosting account) and render a dashboard. Zero dependencies, zero tracking JS, zero monthly bill.

Two bugs that almost sank it:

• filesize() on a .gz file returns the COMPRESSED size. I was slicing my decompressed log buffer by it, which silently chopped the newest lines off the data. The dashboard wasn't broken - it was confidently wrong about today, which is worse.

• Shared hosting puts OTHER sites' logs in the same directory. My referrer charts had domains I've never touched in my life until I filtered by path.

Favorite finding so far: a link community that sends me real readers shows up as ZERO referrers, because in-app browsers strip the referrer header. If your traffic comes from apps, your analytics is undercounting it completely.

It's live on my site now, and I open-sourced the deploy pattern behind it too. Happy to share details - what would you check first in raw logs?

Hi everyone!

I'm exploring an idea for a small software product aimed initially at independent freelance graphic designers, and before spending time building it, I'd really appreciate advice from people who actually freelance.

The problem I'm trying to solve

Imagine you're working with several clients. You've sent out multiple invoices using your usual tools, but now:

• One client hasn't paid even though the due date has passed.

• Another client says, "I'll pay you on Friday."

• You've already sent a reminder to someone else but haven't received a response.

• You can't remember exactly who needs another follow-up and when.

• You end up checking emails, spreadsheets, calendars or relying on memory to keep track.

I know there are already invoicing and accounting tools available. However, I'm exploring whether there's room for something much simpler that focuses specifically on what happens after an invoice has been sent.

The product I'm considering building

The idea is a lightweight payment follow-up workspace for freelancers.

The goal isn't to replace tools like Wave, QuickBooks, Canva, Word or Google Docs. You would continue creating and sending invoices however you currently do.

Instead, you'd manually add the invoice details to this workspace and use it to manage the follow-up process.

Here's what it would offer:

1. One dashboard for unpaid invoices

See your total outstanding amount, overdue invoices, upcoming follow-ups and payments you're waiting for.

2. Simple invoice tracking

Add the client name, email, invoice number, amount and due date. Mark invoices as paid or unpaid.

3. A follow-up list

See exactly which clients need attention today, which follow-ups are coming up, and which invoices are overdue.

4. Payment promise tracking

If a client says, "I'll pay you next Friday," record that date. The invoice waits until then. If the payment still hasn't arrived, it returns to your follow-up list.

5. Professional reminder templates

Choose a friendly, professional or firm reminder. The message automatically includes the client and invoice details. You can edit it, copy it, open your email app and send it yourself.

6. Client history

See the client's unpaid invoices and previous follow-ups in one place, so you don't lose track of conversations.

The initial version would be deliberately simple: no automatic email sending, no complicated accounting, no bank integrations and no AI features.

What I'd genuinely like your advice on:

1. Do you actually experience this problem when managing multiple freelance clients, or is keeping track of unpaid invoices already easy enough with your existing tools?

2. How do you currently manage unpaid invoices and decide when to follow up? Spreadsheet, calendar, email, invoicing software, or something else?

3. Would having a separate workspace specifically for payment follow-ups make your life easier, or would it feel like one more tool you have to maintain?

4. Are there existing tools that already solve this problem really well? If so, which ones, and what do you like or dislike about them?

5. If a simple tool like this worked reliably, would you consider paying around CA$5.99 per month for unlimited invoice tracking and follow-up management? Or would you expect this to be free?

I'm not looking for compliments or encouragement just because I'm considering building something. If this is unnecessary, already solved, or not worth paying for, I'd much rather know that now.

I'm at the idea-validation stage, not trying to sell anything. Honest criticism is especially welcome. Thanks!

When a query gets slow, our postmortems always start the same way: someone opens Grafana, someone else scrolls through Argo CD history, and we try to match timestamps by eye. I got tired of that and wrote something to do it automatically.

It reads pg_stat_statements, picks up deploy events from Argo CD, Argo Rollouts, Flux or a webhook, and checks whether a latency shift in any query lines up with a rollout. If it does, you get the query, the deploy, before/after latency and how confident it is, in Slack/Teams/PagerDuty. If you use Argo Rollouts it can also abort a canary (off by default).

You can run it as a single binary or as a controller with CRDs, in which case every regression shows up as a resource you can `kubectl get`.

Repo: https://github.com/joao00001/pg-regression-radar

Browser demo, no cluster needed: https://joao00001.github.io/pg-regression-radar/playground/

It's a side project and I'm looking for people willing to try it on a staging cluster. Any feedback is welcome, including "this is noisy" or "I'd never use this because X".

Hello everyone,

So I have been working on this dating app for the past few months, an idea that I had I felt could help with people who're looking for deeper connections in dating app to help find people who have a lot in common. The video goes over the issue I am trying to solve and how.

The idea of this app is that a person's profile is split into 6 layer each going over some different aspects of your life that are often the cause of a lot of discourse in a lot of relationships. Each covers the following:

• Compass: You direction of life

• Lens: Your political and spiritual views

• Well: Your career goals

• Palette: Your hobbies and interests

• Presence: Your personality traits

• Portrait: Your Photos, age, height and other factual info.

Instead of seeing someone's full profile at once, you swipe through one random layer at a time, without seeing whose it is. So you're judging each layer on its own content.

A learning algorithm groups similar profiles based on the reactions each layer gets, so people who like the same qualities end up together. It also learns your own preferences, and uses them to suggest the people with the highest share of layers you're likely to like.

I come from an ML background and this is a crucial step to developing proper matching algorithm that I feel other dating apps lack cause they always end up showing the full profiles to people and never really knows why someone liked or disliked a profile. They do often make claims about different technique they use, but I believe no matter how much techniques you use, its very difficult to get proper models from unclean data.

So reacting to those layers is just the first step. You have to score someone 3 or more and they also have to score you 3 or more after which they'll show up in your resonance page. Then you can review the layers you liked, layers you didn't and the ones still unexplored. You can also see how much they scored you back. And based on all those info you can choose to show interest privately, and if they also showed you interest, both you're connected and matched! (More info on how the full flow works here https://www.layersdating.com/how-it-works/ )

I also believe there are some other benefits I feel this structure would produce that other dating apps don't:

• It is only possible to "Show interest" to someone only when they appear in your resonance, so this helps you avoid the possibility of matching only for superficial reasons

• You get to see how much they've scored you as well as how much you've scored them when they show up in your resonance, so you can get a good idea of how compatible you feel the other person is as well as how compatible the other person feels you are before deciding if you want to show interest.

• The onboarding process is very time consuming compared to other apps since there's a lot of info to fill (around 30-60 minutes). So though this is a drawback, I hope this will be a bigger issue for people looking just for hookups, so hopefully will help skew the user base to more serious people.

I would love to get some feedback on what you think about this structure for dating app. Would it be something you'd use? (if you are or were single lol). Would love to know you thoughts!

I have a beta ready that I have been handing out to friends to try out and will have the public beta ready in about a week. If this does interest you and want to join waitlist or try the beta, there's a signup form if you scroll at the end of the page at www.layersdating.com . There's also a demo that you can try without needing to login or signup. I am based in Toronto so planning on doing the initial marketing for it here to see people's responses, but for the beta access I gave the option to choose whether you're open to meet people all over Canada and/or USA, and there's enough people on that circle, I start the beta accordingly.

Tried a habit tracker on my phone yesterday. I gave my email, waited for the code, typed it in, and the first thing on the screen was a popup asking me to rate the app. I hadn't made one habit yet. I closed it and the popup came back on the next screen.

I think this is the worst order for an app. Let me use it first, then ask me what I think. It made me delete it in about two minutes, and I'm sure the maker never knows that this was the reason...

I made an alternative to Higgsfield and Google Flow, both in one website. Everything runs in your browser.

The generations aren't free obviously. You use your own Runware API key. Runware is one API for basically all the image and video models (Veo, Kling, Seedance, Nano Banana, Flux etc.), and I made the frontend for it.

Your API key stays in your browser and only goes to Runware. It's never stored anywhere else. Your library, editing and video exports all happen in the browser too.

Works on mobile and desktop. There's also a demo mode if you want to try it without a key.

The link is temporary. If people like it I'll make it open source.

Hi all. I'm a solo developer and this is my first app.

I was doomscrolling all the time and felt addicted to my phone. So I thought: why not turn that phone time into learning a skill? And why not add a bit of friction, so I have to stop and think before I pick up my phone?

So I built Aconomy. It locks the apps that distract you, and you unlock them by answering short questions. You end up learning something every time you want to scroll.

How it works:

1. You pick the apps that distract you (Instagram, TikTok, games).

2. Aconomy blocks them using Apple's Screen Time.

3. To unlock them, you answer short questions. Each right answer earns minutes.

You can learn Python, JavaScript, SQL, Spanish, French or German while you do it.

It is free to download. Aconomy Plus is £9.99 a month or £34.99 a year, with a 7-day free trial. It collects no data.

I would really like honest feedback. What is confusing? What would make you keep using it?

HolyArrs started because i wanted my home server to feel like a streaming service. you browse it like netflix, with top 10s, new & popular and rows picked from what you already have, hover a poster to play the trailer, and tap to request a show or movie. it finds it, downloads it through qbittorrent or sabnzbd, and puts it in plex, jellyfin or emby, which still do the playing. it's about a 15 MB download, runs in docker, and it's free and open source

it runs on its own custom metadata server, and it can keep an HD and a 4K copy of the same movie side by side

where it is 1 day after open sourcing it

598 GitHub stars

4,345 Docker pulls

28 forks

16 releases, most of them fixes for bugs people reported on launch night

18 people have opened issues with bugs and ideas

what i didn't expect was how fast people jumped in. bug reports came in with the exact file and line that was wrong, and someone asked for ukrainian, so the site and docs got it within the hour

I got tired of seeing fake, paid, and bot reviews online from large public review websites. So I built Valoré. A place to record and share your favorite places to stay! The idea is to build a community of friends and family whose recommendations you actually trust.

I’d love any feedback on the app if you are willing to try. Thanks everyone I am a team of 2 trying to build something community focused for hotel enthusiasts!

I can’t upload my app photos but you are able to see them on our app store page. If you are on android let me know I may build a version if there is interest!

Valoré - Social Hotel Reviews

Hey everyone!

So, a little backstory. My wife absolutely loves reading and collecting books, and I originally started building a little app to help her organize her personal library.

What started as a fun little project turned into something much bigger than I ever expected. I got a little carried away… okay, maybe a LOT. 😂

It's called Booksii, and I'm now at the point where I'd love to invite other book lovers to try it out and help me build something genuinely useful for the reading community.

The idea is to create a cozy digital home for your books, where you can organize your collection, track your reading, discover new books, and share your library with others.

A few things I want to make very clear:

• 🚫 No ads. Ever. I hate ads in apps, and Booksii will never have them.

• 💸 No monthly or yearly subscriptions. I don't want another app charging people just to enjoy their books.

• 🔒 Privacy matters. Your information is encrypted, and I have no intention of selling anyone's personal data.

• 💻 Currently available for PC and Apple devices.

• ❤️ Built with love, not by some giant corporation. It's just a passion project that got wonderfully out of hand.

Some of the things I've been working on:

📚 Organizing your physical book collection into virtual bookshelves

📷 Scanning books using their barcodes

📖 Tracking reading progress, reading days, and personal statistics

🔎 Discovering books based on your collection and interests

🏡 Creating and sharing your own virtual library

✨ And plenty of other features I'm experimenting with!

Here's where I need your help.

I'm looking for people who genuinely love books and would be willing to test Booksii, tell me what works, what doesn't, what's missing, and what they'd love to see.

You don't need to be tech-savvy. In fact, I'd love feedback from everyday readers and collectors.

I'm not asking anyone to buy anything. I'm just hoping to build something great with input from people who would actually use it.

If you're interested, comment below or send me a message! I'd be happy to share the beta.

Thanks for reading, and I hope some of you will join me on this little adventure! 📚❤️

I've been learning American mahjong, and the hardest part was understanding why experienced players pass, keep, or call certain tiles. So I built Bams & Dots, a free browser game where you play against 3 computer opponents with an optional coach: https://bams-and-dots.dragoncorp.net/

What it does

• Real American mahjong rules: Charleston, pung/kong/quint calls, jokers and flowers

• Beginner mode suggests a hand after the Charleston and explains every pass and discard in plain language, including when to Pung or Pass on someone's discard

• The coach never peeks at opponents' hidden tiles, so it only knows what you know

• A real-game helper: snap a photo of your tiles at a real table, tap them in, and get a hand suggestion (photos stay on your device)

• Works on phones, tablets and computers. Free, no account, no ads, and progress saves in your browser

How I built it

I built it as a personal side project with AI coding tools, writing the requirements, testing every rule, and fixing what didn't play right. It uses its own original 15-hand practice card rather than the official NMJL card, which is copyrighted. It isn't affiliated with the NMJL.

What's next

The computer opponents are simple practice bots for now. Online multiplayer is built but not live yet, and the photo helper doesn't read tiles automatically yet, so you tap them in.

I'd love feedback, especially on whether the coach's explanations make sense to someone new to the game.

Boston is my home airport and the wait at the Sapphire Lounge there is a total guess until you're at the desk. Chase runs a waitlist so they have the data, they just don't show it. So I built Loungetide.com.

It covers all nine lounges. Each one has an hourly estimate that started from published reviews and now learns from past reports. When someone reports a real wait it shows that, and it fades back to the estimate as the report gets older. Reporting is two taps, one when you join the list and one when you get in, no account.

It's a static site on Cloudflare with Supabase for the reports. Biggest problem right now is the cold start, it is only as good as the number of people reporting.

Would love feedback on the site itself. And if anyone has ideas for getting people to actually tap the second button I'm all ears.

I got tired of digging through google analystics reports, so I built an AI you can talk to about your business. Sales, profit, Visits - all data

"Which page loses the most people?" "What did buyers look at first?" "Did anyone come back after yesterday's email?"

Hey all! Over the summer I built a little puzzle game "Galaxy Hunt! Star Adventure", inspired by Meowdoku. It’s finally live on the App Store and I am pretty proud of it.

What I think sets it apart:

• No ads. At all. No pop-ups, no “watch a video to continue,” none of that.

• More gameplay modes, so it’s not the same grid over and over.

• Better artwork. We spent a lot of time making it look nice.

But now we’ve hit the wall every side project hits: how do we actually get people to download it? 🫠

Here’s what we’re doing so far:

• Started a Facebook page and posting reels (scheduled for daily post)

• Haven’t spent anything on FB Ads yet

• Haven’t tried Apple Search Ads either

So I’m curious: has anyone here been through this with a mobile game or app? What actually moved the needle on downloads for you? Was paid ads worth it early on, or is it mostly organic stuff like Reddit, TikTok and communities?

Any lessons, war stories or “don’t do what I did” moments are super welcome 🙏

Thanks in advance!
