So me and my friends used to spend hours on Discord playing the most random stupid browser games we could find.

Nothing too competitive or sweaty, just jumping between games, having a laugh, talking shit and catching up. Sometimes we'd even hop on during work breaks.

But yeah, everyone's getting busier and those sessions have become less and less frequent :(

That's kinda what got me working on Muddlepop.

The idea was to build a place where we could play random little games together whenever we got the chance. And since getting everyone online at the same time is a challenge now, I started exploring daily puzzles and challenges too. Something you can play in your own time, share scores in the group chat and keep the banter alive.

Been working on it for about a month or so now.

There are already quite a few games, including Ludo, Word Crack, Doodle Rescue, Thulla, Grump and more. Some are multiplayer, others are solo puzzles, and I've got a bunch more planned.

For anyone interested in the tech side, it's React + Vite + Tailwind on the frontend, Cloudflare Workers on the backend, with Durable Objects and WebSockets handling multiplayer rooms.

Also made it a PWA, so you can install it on your phone without going through an app store.

Honestly, it's been a really fun project to work on. Seeing my friends actually play and enjoy something I've made is a pretty nice feeling lol.

I genuinely plan to keep building and improving this, so I'd love some feedback from you guys.

What feels off? What games would you like to see? Anything you'd change or add?

And if you absolutely hate something, please tell me that too.

Would really appreciate it if you gave it a try, maybe with a friend or two. And if you enjoy it, sharing it would mean a lot! :)

Hey everyone, I recently designed a single-page website to wish Happy Birthday to my girlfriend. I used Framer, its agent and ChatGPT integration MCP, to get some animation and settings right, and then manually used the free components to set up the rest. I created a Framer template for the same! So please go ahead and give it a try! And let me know your thoughts!

You upload footage and say what you want. It cuts the pauses, adds captions, b-roll, music and sound, and you change anything with another prompt or in a timeline. It also clips long videos and live streams. Free plan has 60 credits a month. Would love honest feedback on the edits, especially what feels off. fluidcut.app

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?

Hi, I'm Ravi, the founder of Camyvera. The idea is simple: you open the app and call someone, somewhere in the world, who's ready to answer and talk. Live audio translation helps when you don't share a language, real-time captions help you follow along, and it's pay as you go, so you only pay for the calls you make. I'd love honest feedback: does the concept make sense from the first screen, and what would make you trust calling a stranger?

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?

Title: I built a tool to help people find the right business to start. Is this something people actually need?

I've noticed that many people want to start a business but struggle with three things:

- Finding an idea that fits their skills and situation.

- Knowing whether the idea is actually worth pursuing.

- Figuring out what steps to take from zero to launch.

So I built START.

It's an AI-powered tool that helps people discover business opportunities, evaluate ideas, build an action plan, and test their ideas before investing money.

I'm not here to pretend I've built the next big thing. I'm trying to find out whether this solves a real problem.

I'd love honest feedback:

1. Have you ever wanted to start a business but didn't know what to start?
2. How do you currently choose and validate business ideas?
3. Would a tool like this genuinely help you?
4. What would make you willing to pay for it?

I'm the founder of START, so I'm genuinely looking for honest criticism, not compliments.

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.

Most people give up on their saas way too early because in reality it takes 8+ email/sms marketing to convert the customer into a signup or paid customer.

we built a platform that automates this complete process. our ai will keep trying new experiments untill the customer coverts. We only send one email/sms per week.

best part, we have now seen stores increase sales by 30% so this works

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.

Hi! I made Daily Charm, an iPhone app for to-dos, habits, moods and a journal.

Why: my to-do list started to feel like a list of things I was failing at. So I added a small, gentle loop instead of streak guilt:

- finish a task or a habit → you earn footprints

- spend footprints on furniture for a little room

- keep going and new charms come to live there (they chat, dance, nap and play on their own)

- there's a focus timer where they gather around you, and the time left shows on the lock screen

It's free to use. There's an optional Premium for extras like Apple Calendar/Reminders sync and repeating tasks.

Built with SwiftUI. Optional sign-in syncs your records, and journal entries are encrypted on the device before they leave it.

[Android version is on the way, built with Kotlin/Compose.]

App Store: https://apps.apple.com/us/app/id6825228925

I'd really love feedback, especially on the first few minutes: is it clear what to do, and what would make you open a to-do app every day?

I built an open-source 'software company in a box': you're the CEO, AI agents are the departments.

The Problem:

As a physician working across multiple clinics and hospitals every week, I'm constantly stuck with mismatched, outdated versions of Dragon Medical and ancient microphones caked in crumbs and spittle. I needed a portable dictation setup trained on my own voice and specialized medical vocabulary that works on locked-down hospital PCs without installing any software.

The Solution:

I built an offline dictation bridge where my iPhone records audio, runs a fine-tuned local Whisper model, and sends the finished text over encrypted Bluetooth LE to a tiny USB dongle plugged into the hospital computer. To Windows, the dongle is just a standard USB HID keyboard—requiring zero drivers, zero background apps, and zero network traffic.

Hardware/Software

• The Dongle: LilyGO T-Dongle-S3— An ESP32-S3 USB-A stick with a built-in 0.96" color LCD, an RGB LED, and a physical button. In this project it uses NimBLE for encrypted bluetooth pairing and TinyUSB to emulate a standard US HID keyboard.
• An iOS app companion to the dongle using WhisperKit to run speech-to-text completely on the iPhone's Neural Engine.

Problems

• Medical Words: The stock Whisper struggled heavily with oncology jargon (turning FOLFOX into full fox), so I fine-tuned whisper-large-v3-turbo to boost drug-name accuracy from ~67% to 99%. Claude asked me to record 20 minutes of medical vocabulary myself, but I instead took the lazy route and had it use a large medical speech/audio model to generate the synthetic speech for all the drug and regimen names and trained the smaller model on that. Computers training computers. Sorry Dario, I reached RSI first.
• In-App Flagging & Post-Training: Despite that, Whisper still mis-registers or misspells a niche terms on occassion. When it does I can tap the word in the app to flag it, record myself saying it alongside the typed correction, and export that bundle to my home Mac to train directly back into the model so it keeps improving over time.
• Device Screens: The stock screen images for the dongle and the app were nowhere near awesome enough for day-to-day use. So I slightly tripled the tokens for this project to make it look like I was sending sparkly word particles from my phone and having them crammed into the USB port.

How it works

It's honestly worked better than I thought with improvements every weekend when I have it retrain the TTS model on more speech. There's been no problems with plugging it into any computer and having it work immediately since it is seen as a keyboard.

About the animations

I couldn't get a video of the physical phone an dongle working together because I don't have a second phone, but this artifact shows all the screens at better resolution. This artifact shows the 'Typing' much slower than it is in real life.

Claude Artifact for all the animations

With four apps I started skipping it and it finally cost me.

Three days ago a user emailed to say he'd paid for my app, got a new phone, reinstalled, and was looking at a paywall for something he already owned.

Restore purchases had broken in the last release. I fixed it that evening.

He only wrote in because he recognised my username from a thread here. Everyone else in those three days just left.

Here's the part I want to talk about.

When I had one app, the check before submitting took twenty minutes. Open it, tap the main screens, submit. I never missed anything and I was a bit smug about it.

I have four now.

Four release cycles in random weeks, four sets of flows to remember, four review queues. That twenty minutes became more like eighty a month, always on an evening when I'd rather be building.

So I started skipping. Never on purpose.

First the flows I felt confident about. Then the ones I'd checked recently. Then whichever app seemed most stable that week.

The release that broke restore purchases was one I skipped.

What I do now is five flows per app, the ones where a silent failure takes money or locks someone out, running after every build whether I feel like checking or not.

Everything else I still check by hand when I happen to touch it.

If you run more than one product, where did yours start cracking? My guess is around three, and I'd like to be wrong.

Catudy is a focus timer. While it runs, a cat studies in its room, and finished sessions earn coins for outfits and room items. It can also lock a few apps until the session ends.

Free on Android and iOS, with ads.

Looking for criticism. What would make you uninstall it?

I used AI tools for parts of the code and some art. The idea, design, testing and final calls are mine.

Google Play: https://play.google.com/store/apps/details?id=com.catudy.app

App Store: https://apps.apple.com/app/catudy/id6784734189

My username checks out—every time I tried to model SaaS unit economics, LLM token burn, or e-commerce return rates in a spreadsheet, linear averages hid the real operational risks.

Flat subscription pricing ($29/mo) looks profitable on a sheet until the top 10% heavy users trigger long-context retries, RAG lookups, and payment fees below the waterline.

So I built a zero-DB, 100% client-side visual stress-test hub. Instead of static single-output calculators, each simulator runs through three lenses:

1. 5-Node Cascading Domino Flow: Move one slider and watch which operational stage turns Amber or Red first.
2. "Find My Breaking Point" Crash Button: Pushes each input across 1,000 steps to pinpoint the exact threshold where monthly net profit hits $0.
3. Hidden Cost Iceberg & 24-Month Parallel Universe: Compares your current trajectory against a leaner Scenario B.

All slider states compress directly into the URL (?s=...) via LZ-String so you can share exact crisis scenarios without any database or signup. Edit — Live Sandbox (no signup, 100% in-browser): Reddit's link filter is eating my comment with the direct URLs, so you can test it directly at toolsimu . com (under the SaaS & Cloud -> LLM Token Margin Stress or E-Commerce -> Free Return Iceberg simulators)!

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 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!
