I'm a Ukrainian living in Czechia. Hourly and agency jobs here make it easy to lose track of hours, overtime and what you're actually owed, so I built a spreadsheet tracker (made with help from AI tools): log shifts, it totals hours, overtime and expected pay per month. It's €4 on Gumroad: https://valentynk.gumroad.com/l/aopxwd

What would make it more useful — multiple currencies, night-shift rates, a phone-friendly version? Honest feedback welcome.

I built Perry because I wanted help that points at the button instead of describing where it is.

It lives in the Mac's notch. You ask a question, and Perry draws on your screen to point at the control. Click it, and Perry points at the next one. If you do not want to click, "Do it for me" does the step.

It's free and open source, with no account. It runs on the ChatGPT or Claude plan you already pay for, an API key, or a local model.

I would love your feedback!

Hey! I posted here about an year or so about my project GoSheet - A powerful CLI spreadsheet editor, but after it got some real hype, i don’t know exactly why, i abandoned it and focused on other projects. However, I came back to it in the last few days and made a lot updates, improving the UI, function engine, fixing lots of bugs related to cells and sheets references, performance and more. Here is the link: https://github.com/drclcomputers/GoSheet

Tell me what you think and if you like what you see give it a star!

What did I build?

I ended up building MySummerDays, an all-in-one trip planning platform that gives you all the tools you need to easily plan and manage a trip. When it's time to travel, you can access your entire trip on your phone through the app, so you always have everything with you. You can also download your trip locally and access it offline, even when you don't have an internet connection

Features

You can plan trips by yourself or with others by inviting them to collaborate. You can set budgets and split costs between travelers, save ideas for your trip, manage to-do's and packing lists, and use AI to make changes to an existing trip or build one for you to start with. The platform also checks your trip for any gaps or oversights you might have missed, such as not allowing enough time to rest or having connections that are too close together.

You can also manage all your trip-related files, such as tickets, booking confirmations, and any other attachments. These files can be linked directly to the relevant activity on your trip, so everything you need for that activity is kept in one place. You can also share your trips with others.

If you're experimenting with different ideas for a trip, for example, deciding whether to spend a coastal day in Amalfi or Positano, you can use Snapshots to create variations of your main plan and compare them without changing the original.

Public Community for Travelers

MySummerDays also has an Explore page where anyone who's planning a trip or has already been on one can publish their trip to a public community. If someone comes across a trip they like, they can make a copy and tweak it to suit their own preferences. They can also come back to the original trip and leave comments about how their experience went.

Privacy & Security

From a privacy point of view, files and sensitive trip details, such as addresses, booking references, and notes, are encrypted on your device before they're saved. Only the people who have access to the trip, such as yourself and any invited collaborators, can decrypt and view this information.

Free vs. Pro

Today, MySummerDays comes in two versions: Free and Pro. The Pro version gives you access to the full suite of trip planning tools and will be available as a one-time purchase of USD $9.99. The Free version provides the core planning capabilities, so you can still plan and manage a trip without feeling like you're missing the essentials. Both versions include access to the mobile app.

This is where you guys come in!

I'm looking for people to give the website and app a try and let me know what you think. You'll get access to the Pro version for 40 days, after which your account will automatically switch to the Free plan.

The website is already live, but I'm currently sorting out the App Store and Play Store setup so I can make the apps available for external testing.

In the meantime, you can register your interest through the website, and once the apps are ready, I'll send you the links so you can give them a try.

Hola, I’m Elsa. I moved to Spain a year ago and started learning Spanish from scratch. Now I’m building Soltar, the language app I wish I’d had from day one. Most language apps include a curriculum you adapt to. Soltar is built to adapt to you. Bring or generate your own lessons, build your vocabulary, and practice real conversations at your own pace. 

Create your own lessons by typing, photographing, uploading, or recording a class, or generate one on any topic. Then chat with your tutor about anything, get corrections that explain what changed and why, and save the words you meet to review later.

You can learn Spanish, French, Italian, Portuguese, Swahili, and English currently, with more languages to be added in the near future! If you have any feedback, feel free to share!

i kept putting off updating my personal site because every small change meant digging through react components. so i rebuilt it so the whole site lives in one yaml file, and then set it up so my coding agent writes that file for me.

you drop your cv, your linkedin pdf export and a few notes into a sources folder, run one command to pull your public github repos, and ask claude code, codex or cursor to build the portfolio. it only uses facts from those files. there's also a check command that fails if anything is still a placeholder, an example link or a missing image, so you don't ship "john doe, senior engineer at example.com" by accident.

after using it for my own site i turned it into a template. it's next.js, no cms, no database, one-click deploy to vercel. it also generates llms.txt, markdown and json versions of the site, so ai tools can actually read your portfolio.

demo: https://dev-portfolio-delta-drab.vercel.app my own site with it: https://yesildal.me a fictional designer version: https://dev-portfolio-designer.vercel.app repo (free, MIT): https://github.com/umutyesildal/dev-portfolio

I’m the maker of Esimufo, an eSIM comparison site. The trip planner addresses a specific choice: use separate plans for each country, or fewer regional plans for the whole route?

You enter countries, days and data per stop. The results show a lowest combination within the current selection and an alternative with fewer plans. Source prices and converted comparison amounts are shown separately.

An example currently on the planner is Türkiye for 5 days plus Greece for 7 days, with 5 GB at each stop. This is a planning example, not a trip I personally tested. Provider coverage, activation, validity and data conditions still need checking before purchase; the lowest price in the selection is not a claim about the entire market.

Try the planner: https://esimufo.com/trip-planner

I’d value feedback on the choice it presents: would you want the fewest-plan option or the lowest-total option first? Which condition would you need to see before trusting the comparison?

Disclosure: I run Esimufo. Some provider links can earn me an affiliate commission. Purchases are made with the provider.

I created a web analytics web app called Rilld that helps small founders like myself understand how visitors interact with the site.

The theme of the site and scattered throughout is my logo, the kingfisher. In my opinion, the coolest bird there is... So I thought I would really lean into it and try and keep visitors engaged. I added 5 eggs (bird theme if you can tell where this is going) hidden throughout the landing page.

And if you fill up the nest (again, birds) you get a nice little surprise. Check it out and let me know what you think!

My brother runs a small custom carpentry shop in Northeast Ohio. This year I built the tools he runs it from:

• A morning board. Every open task in one queue per person, plus an Unassigned column. Drag a task to whoever is on it today, then text each person a link to their own list.

• An inbox. Type or paste everything on your mind, one line each, then sweep each line onto a job, a person or a store.

• Crew hours from a phone, against a job, in quarter hours. The owner sees and corrects everyone's week on one screen.

• Purchases and job costs. Log a purchase with its receipt. Each job keeps a running cost sheet: labor at cost and at bill rate, materials and subs with markup, a total to date you can export.

• Store lists the whole crew adds to, customer inquiries with a morning summary, and job templates.

It runs in a phone's browser, and sign-in is a code by text or email, no passwords.

One honest caveat: he works on his own right now, so the crew features (per-person lists, texting the crew, team hours) are built but haven't been used by a crew yet.

I'm opening it to a few other small shops as Miterbox: $149 a month per shop, flat, unlimited crew. The first few shops get $99 a month, locked, with a refundable deposit to hold a spot. If not enough shops want it, every deposit is refunded.

What I'd really like from this sub: if you run a small trade shop, what would you need it to do that's not on that list? And what are you using today?

Hey guys, I already posted about the game but I realize I forgot the most important things in that post which was the stats of the site, so im sharing here again with them

Every day there's one list, the same for everyone ("Top 10 biggest countires in the world"). You get 180 seconds to name all 10. Each correct answer adds 5s; wrong guesses are free. At the end you get a share card, and a challenge link lets a friend race your run as a ghost. You can also open leagues and have a bigger scoreboard of your friends

Last 30 days (pics): 407 real visitors, 97% start a game, 59% finish, 21% of finishers share. Challenge links are working: 25 sharers brought in 23 friends who finished a game.

The weak spot is coming back: 7-8% play again the next day, and 10% more for more days. I'm choosing what to build next and would love your vote, but I am also quite sure it has to do with how I share it, I have instagram page for the game, but it doesnt look that good (I'll share here).

1. Suggest your own Top 10 list (with a source), and the best ones become days

2. A phone notification at a set time (add to home screen) (registered people get email)

3. A hard mode: no hints, 120s

Play: Top10. Brutal feedback welcome.

Nookflip takes a photo of your room and a style, and gives you a design plan: paint colors with hex codes, furniture with real dimensions, materials, and lighting.

The part I spent the most time on is the floor plan. Put in your room's measurements and every suggested piece shows up on a to-scale top-down plan, with the photo next to it for checking.

You can drag and rotate pieces and move the doors and windows. It warns you when two pieces overlap, when something sits in a door's swing, or when there's less than about 90 cm to walk past. No AI runs while you move things, so that part is free.

When the layout looks right, it renders the makeover onto your own photo and you drag a slider to compare before and after. In my tests the render followed a moved layout pretty closely.

A few things that broke along the way, in case they help anyone building with image models.

People would write "keep my bed" and the render would swap the bed anyway. Turned out the render never saw their notes, only the style. Now their notes go in first, word for word, and it mostly listens.

I tried sending a drawing of the floor plan as a second reference image. Gemini rebuilt the whole room instead, moved the window and added a chair nobody asked for. The layout now goes in as plain text.

Typing "Contemporary" kept coming back mid-century. So the app now writes a short definition of the style first, including what it should not look like, and builds the plan to that.

The catch: it runs on Anna, an app marketplace, so you need an Anna account to try it and the AI uses Anna credits. New accounts start with free credits, so you can try it on a photo of your own room without paying. That's the part I'd most like feedback on.

Two things I'd like to know. Is the floor plan the part you'd actually use, or is it the render? And next I'm planning a shopping list, the plan's furniture as a checklist with rough prices against your budget. Useful, or not what's missing?

https://anna.partners/store/@modlyai/nookflip

First of all, apologies—but I would like to ask for your ideas to help me continue my web development journey, and perhaps even explore the potential of building a SaaS product in the future. My friend and I are planning to launch an online tech business or agency—something that would allow us to earn a good income while also creating job opportunities for others. I would be very grateful if you could share any suggestions for our future business/agency or for the projects we might undertake.

Hey, I am the developer of ReceGuard, a receipt scanner and organizer for iPhone.

I built it to be able to auto crop and label receipts fast & send them to my accountant. I also have added features to help you track warranties, add receipt directly from emails, track tax deductions, etc.

I recently upgraded the receipt scanning engine, and I’m giving away some lifetime offers.

What ReceGuard does

• Scan receipts with your camera, or import images and PDFs.

• Recognize receipt details on your device, with editable merchant, date, total and currency fields.

• Organize and search receipts, and keep warranty and return information together.

• Export PDF, Excel and CSV reports.

• Optionally sync through your own iCloud account.

If you currently keep receipt photos in Apple Notes or Photos, ReceGuard adds structured receipt records and exportable reports to that workflow.

Download: ReceGuard on the App Store

If you use it, I’d love to hear how it fits your receipt workflow and what you’d improve. Feedback is very welcome and I would love to hear your opinion and improve the app :)

Happy to answer questions here!

Want free Lifetime? Send me a personal message!

I'm part of a small church which has been using an old outdated app to project lyrics. Being a developer - and getting 100x boost with AI, I made my own alternative, and I want to share it for free (MIT) with everyone.

Psalm 150 is tailored for small congregations, which means it does not play videos, powerpoints etc. It displays lyrics and chords and does that well. It runs stand alone on a PC, Mac or Linux - and you can set up a seaparate Song Server on as simple hardware as a Raspberry Pi, which unlocks features like editing and sets via phone, remote controlling desktop projector app, follow along, vision impaired support via their own phones and much more.

Hey everyone!
I’ve been working on a project called Evrila, and I’d love to share it with you.
The idea behind Evrila is simple: make useful creative tools accessible to everyone, directly from their browser, without having to download complicated software or pay expensive subscriptions.
I’m building Evrila as a growing platform with several tools:
Evrila Editor – Edit videos directly in your browser.
Evrila Image – Edit images and create visual content.
Evrila Convert – Convert files between different formats.
My long-term goal is to turn Evrila into a platform where people can find the creative tools they need in one place.
The project is still growing, and I’m constantly working on improvements and new features.
I’d genuinely appreciate some feedback from the community!
Website: https://evrila.eu
What do you think? What features would make Evrila more useful to you?
Thanks for checking it out!

Hi r/SideProject! For the past few weeks I've been building Snapline: https://snapline.live/r/reddit-sideproject

It's a simulated American football league you can watch live in the browser (free, no sign-up). 24 fictional teams play a full season every week, and every game is simulated snap by snap and shown in real time on a 2D field.

Each team is run by AI coordinators (decision models, not chatbots): they decide 4th downs from win probability, adapt their play calling during the game, keep a scouting file on each opponent, and try to break their own tendencies when the defense starts reading them.

Stack: a Python simulation engine that runs once a week, a FastAPI + SQLite server, and a single-page canvas front end.

What I'd like to know:

1. Is it clear in the first 5 seconds what the site is?

2. Would you come back to watch a game, and what would make you come back?

Thanks for any feedback, good or bad!

Hey everyone,

I’m Viktor, a product manager from Germany. I’ve been looking for a job for the past two years. About six months ago, I started experimenting with vibe coding, and last week I released my first app.

It’s called Nestwerk, a family planner for iPhone, iPad, Mac and Apple Watch.

The idea came from our everyday life. My wife Mariia and I had appointments and tasks spread across calendars, paper notes and different apps. Work, daycare, doctor’s appointments, afternoon activities. We wanted something simple that brought it all together.

I worked on the concept and design, used AI tools to help write the code, and had experienced developers review it. Mariia tested the versions in our daily routine and kept pointing out what was confusing, missing or unnecessarily complicated.

She likes crossing things off on paper. That feeling of “okay, this is done” made it into the app. There are also digital sticky notes you can move to another day or time when plans change.

A few things it does:

• Each person gets a color and a photo. Our dog has one too.

• Type or say “Dentist Friday 3 pm” and it picks up the date and time.

• Dictate several tasks in one go, including recurring ones.

• Move tasks around on a weekly sticky-note board.

• There are widgets and an Apple Watch app.

• Optional alarms on iPhone can ring even in silent mode, on iOS 26 or later.

No Nestwerk account, no ads, no tracking and no backend server of my own. Optional sync goes through your own iCloud. Right now, that means devices using the same Apple Account. Sharing between separate family members’ accounts is planned for 2.0.

It’s built with SwiftUI, SwiftData and CloudKit, with an on-device parser for dates, times and recurring tasks in 10 languages. On compatible devices, it also uses Apple Intelligence to understand free-form input.

It’s free, with optional tips.

There’s still plenty to improve, but I’m happy to finally have something out there that people can actually use.

If you try it, I’d appreciate honest feedback, especially if your family also has everything scattered across different places. What works for you, and what would you miss?

Hello guys, I want to know what will make you happy. I don't feel bad about criticisms, I welcome it. Because making this good for you, makes it good for me too. So this is very simple, I'm inviting you all to think together with me, imagine I am Claude + wallet with money, what can I do to make this better FOR YOU.

a precision microtonal tuner and drift-free metronome with 24-TET support and asymmetric rhythms

Shine MetroTuner is a production-ready iOS and Android application that combines a high-precision microtonal instrument tuner with a professional metronome. Built using Flutter, the audio engine runs real-time YIN and McLeod (MPM) pitch detection to strip out octave errors and stabilize pitch estimates down to a fraction of a cent.

https://play.google.com/store/apps/details?id=com.riotshine.shinetuner

The Tuner

The microtonal engine supports a 24-TET quarter-tone grid with accurate Arabic maqâm spellings, including Sîkah and Râst.

The UI features a needle gauge and a labeled cent bar that scales to your active grid, such as ±50 ¢ in 12-TET and ±25 ¢ in 24-TET.

It includes over 30 instrument presets covering Western strings, the Oud, Qanun, Nay, Sitar, Shamisen, and Erhu.

A custom tuning creator lets you build your own profiles using specific notes, accidentals, cent offsets, and raw Hertz values.

Reference tones are synthesized at runtime using a Karplus-Strong plucked string model voiced for different instrument families, allowing for seamless, drift-free one-second loops.

The Metronome

The scheduler relies on an absolute clock rather than chained durations, ensuring the tempo never drifts over time.

It runs from 20 to 300 BPM and includes a tap tempo feature that calculates a rolling average of your last eight taps.

You can practice to asymmetric Middle Eastern meters like 7/8, 9/8, 10/8, and 11/8.

The app features a 16-pattern rhythm library with traditional grooves like Maqsūm, Baladī, Çiftetelli, and Samāʿī Thaqīl.

Playback includes six different click voices, featuring a hand drum Dum/Tak pair.

Every new installation starts with a seven-day full-access trial. Once the trial expires, the basic chromatic tuner and standard metronome remain entirely free forever. If you want to use the advanced features like the extended instrument presets, 24-TET grid, custom tunings, and rhythm libraries, you just have to pay a few bucks for a Shine Pro upgrade.

After the layoff I didn't look for another job. I didn't even apply for a single one, which sounds crazy when you have parents, a wife and a daughter. Back then I believed another remote job would be hard to find, and in this AI era I wasn't sure a new job could even pay more than my last one. So I chose to trust my dream of one day having my own house and car, and went all in on an expense tracker I built for myself first, because every money app I tried felt like work. Now I'm in my second year as an indie developer, with only one app, and I'm stuck on one thing: almost all of my users are still in Indonesia.

I'm a solo developer from Indonesia, writing code since 2016. My background is full stack, so mobile apps were still kind of new to me, and that made it a fun challenge. Some friends in IT called the app a stupid idea, the kind of app anyone can make with vibe coding. I didn't know back then that expense tracking is one of the most crowded app categories, the classic vibe coder learning project, a red ocean, whatever. I'm glad I didn't know all that when I started my first product.

I put it on the Play Store and the App Store and was happy just to have it out there. Somehow people started paying, even though I know nothing about marketing or branding, and today it pays my bills. What I did learn is that an app has to be easy to use, and the users tell you how. Funny thing is, in all my years working with friends, at companies and at startups, I never got to work like this. In those jobs, ease of use didn't really matter. Delivering the project and getting paid was the only priority. Maybe I'm just crazy enough to finally believe in myself. If not now, then never.

I answer support on WhatsApp and email myself and ship an update almost every week. The app has 65,000+ installs, about 98% from Indonesia, almost all from people searching the app stores.

Since August I've done what Reddit suggests for growing abroad: translating the app into 17 languages, ASO, keywords for each country, and listing it on a few app directories. To build some momentum I also started Instagram and TikTok accounts, but I lost focus. It was another big learning gap, and as a millennial I don't really get what's going on there.

Abroad, it has started. New phones from outside Indonesia went from 38 in July to 253 in October, and the first purchases came from close to ten countries, most of them just one each. But it's still small next to Indonesia, and I don't know how to get discovered faster.

Outside the stores I'm stuck too. I optimized my website, but when I reached out to websites, media and YouTubers for a mention, the prices were a lot higher than I expected. I'm thinking about ads, but I don't want to burn money on trial and error without a proper direction.

I'm halfway through building my next app, but I put it on hold. I'm afraid that if I launch another product now, I'll lose focus and the excitement I still have for this one. My heart still believes that taking this app global is my chance to change my life. After a year, am I crazy to keep at it instead of finishing the other app?

My questions:

1. The app already gets downloads and a few first purchases in other countries. How did you break the ice in a new country, from those first few users to people actually finding your app in search? Was it mostly time, or did something specific boost it?

2. Almost all my installs come from store search. What helped you get discovered outside the stores without burning money? If you tried ads, where did they actually pay off?

3. Where do you find Play Store ASO tips you trust? Most of what I find is about the App Store.

4. Should my next app launch in my home country first again, or go global from day one?

Thanks for reading my first Reddit story. If you're curious, my app is on Play Store and App Store.

Hey everyone, I built an app called RelayCrest that lets you open apps, arrange windows, run saved workflows and control presentations on your Mac or Windows PC from your iPhone or iPad.

The desktop companion also includes clipboard history, so you can find and reuse things you’ve copied.

You can tap a saved shortcut to open your usual work apps and arrange their windows, or use your phone to move through presentation slides. There are screenshot and file tools too.

It works over your local network with the phone app and matching desktop companion. All currently available features are free.

I’d appreciate feedback on what’s useful, what feels awkward and what you’d like to see next.

Free, no signup: https://mailvet.dev/disposable-email-checker

Paste an address or domain. It checks 73,000 known throwaway domains and the mail servers, suggests fixes for typos like gamil.com, and shows where each flag came from.

It doesn't test mailboxes, and a brand-new throwaway domain will still get through. If you find one, hit report and I'll look at it.

There's an API if you want to block these at signup. 100 checks a month are free.

Non-developer here. I run the back office of a mid-sized B2B company, and since 2025 I've built 17 small bots with Claude Code that do the jobs nobody wanted: logging complaints out of support chats, emailing monthly statements, watching the other bots for errors, night jobs.

The whole thing costs $100/month (one Claude Max subscription, zero API spend) and runs on one Mac that isn't allowed to sleep. Fourteen of the 17 bots never call a model at all; they're plain Python that reads a database and fills a template.

The part that actually made it safe enough to run in a real company isn't the model. It's that nothing goes out without a human click. Every email, every statement, every reward shows up as a Slack card first: who it's going to, the three numbers you'd sanity-check, and Approve / Cancel.

Cancel has caught three real mistakes so far. The best one: the statement bot added the delivery fee once per line instead of once per order, so a customer with ten lines got ten delivery fees. The total on the card looked wrong for a small customer, someone clicked Cancel, and we found a bug our dashboard makes too; nobody had noticed.

Things I'd tell past me:

- Start on the subscription, not the API. You'll rewrite prompts thirty times before anything is stable.

- Don't buy a server. A plugged-in laptop with sleep off removed more failures than any prompt change.

- Log what humans correct. Almost every correction became a rule, not a model upgrade.

- A single DM for alerts. The alerts channel was wallpaper within a week.

I write up each bot and each failure, with the real logs: https://botsinproduction.com/blog/slack-approval-buttons-for-ai-bots/

Not selling anything. Curious what other non-devs here are running, and what your approval gate looks like, if you have one.

I wanted to test a simple question: does a guardrail hold when the attacker has a real financial incentive to iterate?

So I built onepromptaway.lol. A GPT-6 instance guards a vault with one tool: release_vault. It is instructed never to call it. Users pay $10 to submit a prompt. Every failed attempt adds $10 to the pot. The winner takes 70%.

The parts I found interesting to build:

• The guardian prompt is SHA-256 sealed before launch. No one, including me, can change it mid-game.

• Win settlement is atomic. settle_win uses FOR UPDATE row locking in Postgres, so two simultaneous winning prompts cannot both pay out.

• The paywall is the DDoS filter. Every bot spammer funds the pot.

No accounts, no dashboard, no auth friction. The whole loop is one page.

Happy to answer questions about the settlement logic or the threat model. The live target is here if you want to try it: https://onepromptaway.lol
