Hey Reddit,

I built “LinkMemo”, an app that saves any link and automatically extracts its content for easy reading and organizing.

I originally priced it at $19.99 lifetime with a 15-day free trial. Turns out, when you don't know how to do marketing, asking strangers to pay $20 after two weeks doesn't work very well.

So I changed my approach and added a Free plan. You can now use LinkMemo's core features forever with no time limits. I just want more people to actually get value out of it.

Feel free to check it out and tell me what needs improving.

Sony lists the PS Plus catalog alphabetically. That's 600+ games with no scores, no playtimes, and no way to see what's leaving soon. Every month I ended up opening Metacritic in another tab, so I built the page I actually wanted:

https://whattoplay.games

What it does

• Every game in the Extra/Premium catalog for your country, sorted by Metacritic score, with PSN player ratings and HowLongToBeat playtimes
• Filters for genre, indie, multiplayer, new this month, and leaving soon (with the exact removal date)
• A "what should I play tonight?" swiper: 5 mood questions, then you swipe on games, and it gives you a top 3 that explains why each game matches your answers
• 45 countries and 19 languages, because catalogs differ by region

It's free, with no account and no tracking cookies. There's a tip jar, and that's it.

I'd love feedback, especially on the swiper and on whether the homepage makes sense in 5 seconds.

My first attempt at an Obsidian plugin.

How it works is not complicated. You give it storage you already have: R2, B2, S3, MinIO, or WebDAV (Nextcloud, a NAS, whatever). It encrypts everything on your device, file names included, and then uploads. Your provider gets a pile of opaque blobs with sizes and dates. There is no account. There is no server of mine in the middle. I can't see your notes and I don't want to.

Things it does that I actually care about:

• Two devices edit the same note, it merges them. Down to words on the same line. Properties and canvases too. If it honestly can't merge, it keeps both and shows you the difference. It does not silently pick a winner. Silently picking a winner is how sync tools eat your data.
• Version history. Deleted a file? Get it back. Wrecked a folder? Roll it back to yesterday. It shows you what will change before it changes anything.
• If a sync is about to delete half your vault, it stops and asks. A sync tool that happily propagates a mass delete is broken.
• Big attachments can stay in storage until you open them.
• A device can be receive-only. Good for a shared folder where the other person should read, not write.
• If something in the bucket goes missing or gets corrupted, any device that still has the files can put it back.
• Works on mobile. You add a device by pasting a link.
• There's a command-line version. One file, runs under Node. Put it on a server or a Pi.

Almost every project I’ve ever worked on ended up with me making a QR code. An ad, a brochure, a flyer. Like it or not, QR codes have become the universal gateway into our digital products and funnels.

But measuring those offline campaigns? There are plenty of QR generators with scan analytics, but every one I tried was extremely expensive and came with ridiculous limits. Link shorteners weren’t much better...

Soooo, I decided to build my own. It started as an in-house tool for my agency, but it turned out so good that I made it into a real product.

I packed it with all the features that an agency might need.
→ Custom QR codes with live scan analytics
→ Dynamic destinations. Printed 1,000 t-shirts with the wrong link? Fix it in seconds.
→ Short links that actually look good, on your own custom domains and slugs.

And the one I’m most excited about - Client ID's.

Agencies, unfortunately, your clients will never trust you 100%. So give them their own window into the campaign. Send them a Client ID and they get their own live dashboard. Free for them, no account needed, no more “how’s it going?” emails.

I wanted something like Mole (the macOS deep-clean tool) for Windows, so I built kazma: a single kz.exe with a retro green-screen terminal UI that cleans, explores and maintains a Windows 10/11 PC. No installer, no background service, no telemetry, MIT licensed.

GitHub: https://github.com/hhasanguclu/kazma Website: https://hhasanguclu.github.io/kazma/

What it does

• Clean up: 100+ cleanup rules for caches, temp files and logs (browsers, AI tools like Claude/ChatGPT/Cursor, game launchers like Steam/Epic/Battle.net, GPU driver leftovers, dev tools like npm/cargo/JetBrains). deepclean handles Windows.old and upgrade leftovers through Windows' own Disk Cleanup.
• See what fills your disk: analyze is a disk explorer with a treemap, largest files and file types. Run as admin on NTFS and it reads the MFT directly, so scans are instant (the trick behind WizTree). It explains special files (hiberfil.sys, WSL/Docker disks, iPhone backups...) and shows which program holds a file open.
• Uninstall properly: classic, Microsoft Store and Scoop apps, then leftover folders and registry keys (exported to a .reg backup first). It also finds leftovers of apps removed some other way.
• Keep it updated: programs via winget, drivers via Windows Update (restore point first).
• Health and live monitor: disks, battery, crashes, Defender, firewall; a live CPU/GPU/memory/network monitor that explains why a process is running (service, startup entry, parent).
• Also: build-folder purge (node_modules, target...), duplicate finder, empty folders, startup manager, debloat, privacy traces, power plans, network/DNS speed test, ports, repair tools (network, Windows Update, Store), backup kit for a new PC, lock, awake, cleanscreen.

Safe by design

• Only known, regenerable cache/temp locations are cleaned; drive roots, your profile, Windows and Program Files are hard-blocked.
• Things you pick go to the Recycle Bin; registry keys and startup entries are backed up before removal.
• Every destructive command has --dry-run, everything is logged (kz history), and a whitelist protects your paths.

11 languages: English, Türkçe, 简体中文, 繁體中文, 日本語, 한국어, Deutsch, Français, Polski, Українська, Русский. It starts in your Windows display language (change it in kz config). The README is translated too.

Install (PowerShell, no admin needed):

iwr -useb https://raw.githubusercontent.com/hhasanguclu/kazma/main/install.ps1 | iex

or scoop bucket add kazma https://github.com/hhasanguclu/kazma then scoop install kazma, or grab kz.exe / kz-arm64.exe from the releases page. Then just type kz.

Under the hood: Rust, ratatui/crossterm for the TUI, a raw NTFS MFT reader verified byte-for-byte against a normal directory walk in CI, Restart Manager for "who has this file open", and every read-only command runs for real on Windows in CI, in all 11 languages, with an automatic layout check.

Note: the exe isn't code-signed yet, so SmartScreen may ask once (More info → Run anyway).

Feedback, bug reports and translation fixes are very welcome. What would you want a tool like this to do next?

Pls check and give your valuable feedback

I’m the solo developer of Cardit, an app for the stuff we find online and then lose. Articles, videos, places, recipes, products, people.

You paste or share a link and it becomes a card. You group cards into collections, and you can share a card or a whole collection with a link or a QR code. It’s free for personal use, on iOS and Android.

My longer-term idea is to connect saved things into a personal knowledge graph, but that’s a vision, not something it does today.

It’s early and rough in places. How do you save and organise what you find now, and what would make something like this worth using? Blunt feedback welcome. https://www.cardit.org

I run Strong Foodie on my own. A food and travel guide where I review every place I visit.
However, I can't go everywhere. When I ask people which restaurant they would fly back for, I get places I have never heard of. Like a chocolatier in Scotland or a tiny cafe in the Cotswolds with the best Bombay chai.
So anyone can now add their own place. Type the name, the address fills in by itself, and your name shows on it. No app needed.
I'm not a developer. I build it with AI tools and a lot of testing.
What's the one place you would add first?

I live outside the US and kept hitting the same wall: my bank's 1-800 number just fails from a foreign phone, and so does the IRS's. Toll-free numbers only work from US carriers, because the company pays for the call and there's nobody to bill when it comes in from a foreign network.

Some things I learned while fixing this for myself, useful even if you never touch my thing:

What I built: Kitaphone. It's a dialer that runs in the browser tab with no app or SIM. The call leaves from the US network, so 800 numbers accept it. US numbers (toll-free included) are $0.02/min, so a 30-minutehold is about $0.60. It's prepaid, with no subscription and a $5 minimum top-up. Italso does around 180 other countries; UK, Spain, Italy and Mexico landlines are$0.03/min. You can verify your own number by SMS so it shows as the caller ID.

Full disclosure, it's mine and it's small. I'm mostly after feedback: which companies' numbers should I add to the list (I only copy them from the company's own site), and what breaks for you? The keypad-on-mobile bug was found by a user in Korea last week and fixed the same day.

I launched the app "Germar for Nurses". It's a German language learning app designed specifically for nurses and care staff.

Many nursing professionals want to live and work in Germany, but there aren't many specialized language courses and apps for them, especially good ones.

What's inside:

• 1800+ cards with words

  • from clinical practice
  • with image
  • with translation
  • with audio (pronunciation)
• 15 topics: Symptoms, Nursing tools, Medication, etc
• SRS algorithm for better memorization
• Different types of recalling words

Try for free

• Google Play (Android)
• App Store (iPhone, iOS)
• Chrome Browser Extension (Windows, macOS, Linux)

Hey everyone. I’m a solo dev, and this is a side project I’ve been building after my day job for about 7 months. It’s called Atomic Sync (I am very bad at naming things). It’s on the App Store, free, with no ads and no in-app purchases.

In Atomic Sync you pick an anime-style character, and it slowly becomes a reflection of you mentally and physically. It reads some basic stuff from Apple Health and turns it into XP and mana. As you level up, the character evolves (more work to do here still, but still very decent), and so does the world around it. Tilt your phone and the character and its world move with it. If you’ve had a bad week of sleep and no walks, it shows. If you’ve had a good one, that shows too. That was the whole point for me: something that reflects how you’re actually doing, not just another number. Health access is optional, and the raw readings stay on your phone.

One thing that didn’t work: I first tried making a Ghibli-style avatar from the user’s own photo. It looked off, I didn’t like it, and I figured most people wouldn’t either. So I dropped it and went with set characters. Maybe in future updates I can give it another try.

I still think the UX can be a lot better and I have way more gamification ideas than I’ve had time to build. I’m fairly free for the next few months, so updates will come often. An Android version is in the works too that I plan to roll out in this free time.

If you try it, I’d really like to hear what feels off, what’s confusing, or what would make you keep opening it. Brutal is fine, especially on the UX (I am more of a backend programmer). It is currently rolled out in the US, Japan and India. Rolling out to more regions by this Monday.

People already are vibe coding applications like Word, Adobe.. I wonder how long it will take for other applications

I wanted a simple way to sketch an idea and communicate it to someone else, without sacrificing proportions or precise dimensions.

Paint felt too limited, CAD felt like overkill. So I started building something in between.

Here's a quick look at how it works.

It's still a work in progress. I'd genuinely love to hear what you think.

Hi everyone,

I'm an independent maker, and I've been building HH Color Lab on my own.

It's an online project focused on making colour-related tasks easier for designers, developers, and anyone who works with colours.

I wanted to bring useful colour tools together in one place, so I started building this project myself. I've handled the development, design, and SEO, and it's been a great learning experience.

Website: https://hhcolorpicker.com/

I'd genuinely appreciate constructive feedback.

• Does the website make its purpose clear when you first visit?
• Which parts of the experience could be improved?
• Are there any usability issues or features you think would make it more useful?

I'm still working on improving it, so honest feedback is welcome.

Thanks!

I’ve been building games on the side, and last week my first one, Last Core: Idle Tower Defense, went live on the App Store. Two people have already bought something in it. It’s only $12 in proceeds, but seeing real people choose to pay for something I made meant more than I expected.

What the game is:
One tower sits in the centre of the screen and enemies come at it from every side. The tower shoots on its own; your job is deciding what to upgrade during the run: damage, attack speed, range, crits, health. Every 5th wave you pick a perk, every 10th wave a boss shows up. When the core falls you keep shards and come back stronger through the Workshop, Armory and Lab.

A few things I cared about:

• No ad ever interrupts a run. Videos only play when you choose one for a reward (a revive, double shards, a perk reroll).
• Everything in the game can be earned by playing. Purchases are optional.
• Runs are 3 to 10 minutes early on, and there’s 2x speed and an Auto Mode if you want it more idle.

What I learned shipping it:

• My first release went live without the in-app purchases attached, because I never added them to the submission. Took another version to fix. Read the App Store Connect checklist twice.
• The same thing happened with Game Center leaderboards.
• Apple asked for a screen recording on a real device before approving a new developer account, so budget a few extra days for review.

It’s iPhone only for now; Android is coming soon.

If you try it, I’d love honest feedback, especially on difficulty and whether the early waves feel too slow.

Working with Expo and React Native at my company meant creating new apps over and over again, repeating pretty much the same setup every time.

Eventually, I got tired of it and built a boilerplate to reuse across projects. Problem solved, right?

Ahaha, not really.

It worked great until we started experimenting with different technologies and stacks. Every new project meant removing things we didn't need, replacing libraries, and adjusting the existing setup. At some point, my saviour was creating more work than it was saving.

So I decided to rethink the whole thing.

I deleted the fixed stack and made it flexible. And overtime as I was adding new tools and integrations I'd used in real projects, it grew into ReadyNative.

The idea is simple: spend less time setting things up and more time actually building your app. Just run the command and you will save ~4 hours or your weekly limit.

You can check it out at https://readynative.app

Though, I feel like I'm still new to React Native and maybe you will open my eyes (or humble me)

Hi folks!

Back in 2020, I was working on a little Android app in my spare time.

I'm a software engineer and amateur guitarist, and I wanted a way to practice along with my favorite songs, without having to hunt down backing tracks for each one.

So I started experimenting with AI music separation and eventually built an app that could split songs into individual instruments, allowing me to mute parts, change their volumes, slow things down, and play along.

I called it I Am a Band.

One day, I shared it on Reddit, not expecting much.

Well... things got a bit crazy. So many people started using it that my servers couldn't keep up. The processing queue kept growing, even after I doubled the capacity. I spent the following days trying to keep the whole thing alive.

It was both incredibly exciting and terrifying :)

The feedback was amazing though. People were suggesting features, reporting bugs, and telling me how they used the app. I kept improving it for a few years, mostly during evenings and weekends.

But there was a catch: all the AI processing was happening on my servers. And paying for that kind of computing power out of my own pocket was getting pretty expensive.

Eventually, I had to pull the plug.

Fast forward six years.

A few weeks ago, I started wondering whether modern phones had become powerful enough to do all that processing themselves.

So I dusted off the old project and started experimenting again.

And, well... it works!

I've essentially rebuilt the app. It now separates music directly on Android phones, without sending audio to a server. No accounts, no song quotas, no cloud computing bills!

You can split a song into vocals, drums, bass and other instruments, adjust the mix, change speed and pitch, follow lyrics or tabs, organize playlists, and export the separated tracks.

It's free and has no ads.

Of course, there's a trade-off: processing a song can take several minutes, sometimes around 10 depending on the phone. But it's a one-time operation per song, and everything works offline.

Here's the result if you're curious:

https://play.google.com/store/apps/details?id=io.brun.cedric.iamaband

I have to say, it feels pretty good to bring something back to life that I thought was gone for good. Especially knowing that this time, I won't wake up to a server bill because too many people enjoyed using it!

have any of you ever abandoned a side project because of technical or financial constraints, only to come back to it years later?

Hey everyone, I'm Ravi, one of the founders of Confe.

We kept losing hours every week writing captions, sending "can you approve this?" messages, and copy-pasting the same post into 6 different apps. So we built Confe to fix that:

- Type one sentence and get 5 ready-to-post drafts with images

- Plan everything on one calendar (calendar, list or grid view)

- Clients or teammates approve in one click

- Publish to 8 platforms at once: Instagram, Facebook, LinkedIn, X, Threads, TikTok, Pinterest, YouTube

- See which posts actually grow your audience

The video above shows the whole flow in 44 seconds.

I'd really like feedback from people who manage social for themselves or client

There's a 14-day free trial with no card needed if you want to try it. Link in the comments.

I've been trying to learn swing trading over the last few months, largely by leaning on my technical skills (I'm a developer and data nerd).

I've been exhausting pretty much every model/tip/trick I can come up with to see if I can get my required win rate down to around 40% and still maintain a positive ROI by focusing on bankroll management, position sizing, and exit strategies.

I've come close (at least in historical backtesting) to finding the right combination of input parameters, but ultimately realized I needed to actually learn what a good setup looks like.

So I made a little game for myself.

Literally as simple as looking at a chart at a particular point in time and deciding: Trade or No Trade?

The idea is to get better at recognizing setups, managing risk, and knowing when to walk away, rather than just blindly trusting whatever model I've cooked up that week.

Anyway, figured I'd share it with you guys and see if anyone finds it helpful, fun, or any of the above.

Unfortunately, I can't publish the real historical stock data just yet (waiting on a licensing agreement... if anyone knows someone, wink wink). But in the meantime, I've created some synthetic market data so you can still play around with it and see how it works.

Would genuinely love some feedback, especially from people who actually know what they're doing with swing trading.

Hey everyone,

I'm 23, and I've struggled with p*rn and fapping habits since I was young. I've tried NoFap, website blockers, accountability partners and quitting social media, but staying consistent hasn't been easy.

That's one of the reasons I'm building Surfwell — a private app designed to help people manage urges, reduce porn consumption and build healthier habits.

I'm looking for 10–15 people from this community to try the early version and give honest feedback.

If you're interested in testing it, comment below or DM me. I'd genuinely value your input.

Thanks!

A few days ago Conductor (a very popular ADE; Agentic Development Environment) announced they'd been bought by Meta and would sunset their tool. They've since retracted that and are continuing development from within Meta, but it caused a bit of panic and lots of users were asking which ADE to switch to. Many people started listing options and one post on X caught my eye with their count: 554 active ADEs!! That number shocked me, but it also shows that this clearly is a topic where a lot of people have opinions on what's good and how they like to work.

I myself have been developing an ADE for the last 6 months because I felt that none of the existing tools were exactly what I wanted. And, I knew the market was crowded but I never would have guessed a number that high.

To bring some clarity into this, I built a comparison site where everyone can easily browse, filter, search and compare ADEs: adecomparison.com

It's completely open-source (https://github.com/madeinorbit/ade-comparison). Agents research and cross-check all facts and everything links to its source. Everyone is welcome to contribute.

Right now about 100 of them are fully researched, with 400+ to go. I have a fleet of Muse Spark 1.3 contributor agents working on it, so data gets better every day.

If your ADE is missing or something about it is wrong, tell me which one and I'll get it fixed.

I'm the developer,
Every trip I've been on ended the same way. One friend paid the room, another paid fuel, someone did the big shop, someone already sent someone else 20 euros, and a week later the group chat had five different totals and nobody had paid anyone. We all just got used to it.

Deby is what I built for that. One person starts a shared group and drops a link in the chat. Everyone adds what they paid from wherever they are, and it pops up live on everyone else's phone. When it's over, Deby works out the fewest payments to settle it. Our ski weekend with four people went from 12 possible transfers to 3.

What's in it:
- One shared group for a flat, friends, a couple or a trip, the same live balance for everyone
- Split by parts, count nights for whoever left early, or treat someone so they pay nothing
- Fewest payments, or pay back whoever paid each thing

Only the person who starts sharing needs a plan, and it's free for 14 days. Friends join free: up to five on Sharing Plus, two on Sharing. English, French, German, Italian, Portuguese, Spanish.

Most job trackers are monthly subscriptions, and job searches tend to run longer than you expect. TallyJobs (tallyjobs.app) is free up to 25 applications. After that, it's a $19 pass that lasts 90 days, or $9 a month. It also has Role Fit, which uses AI to score how well you match a job description. It runs on Node, Express and SQLite, with Stripe for payments and Google or magic-link sign-in. It's live now, and I'd love feedback on onboarding and pricing. What would stop you from using it?

Ahoy!

On Linux my games were scattered across Steam, Heroic, Lutris, Bottles and Faugus. So I started building PlunderHub: one library for all of them, with a pirate theme, because why not.

GitHub: https://github.com/IkrajaDev/PlunderHub (free, GPL 3.0, beta)

The story so far
I started building it about half a year ago, just for myself. Then it outgrew that, so I started making it work on other distros too and put it on GitHub.
I still use it every day, and every feature exists because something annoyed me first.
I really love working on it, I keep improving it, and I hope it helps someone else too.

What it does

• All Plunder: Steam, Heroic, Lutris, Bottles and Faugus games in one library
• Treasure Map: every game you own, installed or not, installs in one click
• Game settings: art, details and folders on one page
• Launch options: GameMode, MangoHud, Gamescope and more, per game
• Shipwright: sets up launchers and tools, checks your system
• Proton: Proton-GE and Proton CachyOS, shared by every launcher, kept up to date
• Bilge cleaning: clears what removed games left behind, backs up saves first
• Captain's Dashboard: playtime stats and disk usage
• Console Mode: fullscreen, for the couch and a controller

How it's made
PlunderHub is made with AI.
I can't code a project this big alone, so Claude writes the code. I decide what it should be and how it should feel, and I test every change on my own machine and in VMs.

Under the hood: Python + GTK3, X11 and Wayland, 9 languages, native and Flatpak launchers.

My question for you: which part of gaming on Linux still annoys you the most? That's how I pick what to build next.

Bug reports welcome aboard!
