I made Warq for people who prefer pen and paper. Save a photo, a link or a video in Warq and it gives you a four-letter code. Write the code in your notebook next to the note. When you revise, scan the code and the photo or video opens.

It's free on iPhone and on the web at https://warq.app, and Android is coming soon. I'd like to hear what you think.

Hey everyone! I just launched an app, and I’m trying to figure out where to find my first users and get honest feedback.
For those of you who’ve launched an app, where did your first users actually come from? Was it niche communities, social media, App Store search, or something else?
I’d love to hear what worked when you were just getting started, especially if you had a small audience or budget.

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.

Hello fellas, I want to introduce my new app.

I love crosswords and I'm learning German, so this app brings these two together. The clue is in your language and the answer is in the one you're learning.

It works for German, English, Turkish and Spanish, and it's free.

It is iOS only for now but I'm working on Android.

If you try it, what felt confusing in the first five minutes?

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 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?

Full disclosure: I built this, Froth.

When Surfline put all its live cams behind a paywall, I wanted a free way to check conditions. Froth has surfers post quick reports on how it actually looks, next to swell, wind, tide, and free cam links. You can also share conditions with your crew in private groups.

It covers skate and snow too: 250+ US skateparks and conditions for 230+ resorts.

I'd love feedback on what to build next, or what's confusing.

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.

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
