Ever had one of those "huh, I've always wondered how that actually works" moments during the day, and then it just goes nowhere? Ever wish you could replace doomscrolling with learning something fun?

I do. This is why I built Erudity.

Bite-sized facts on anything you can think of. You type in a few words describing what you want to learn, or explore hundreds of ready-made subjects. Seconds later, Erudity turns it into a proper little course: a deck of cards you swipe through, with a Deep Dive behind every card when you want the longer story. No source material to upload, no curriculum to choose, no 40-minute video. Just the thing you were curious about, explained well and actually enjoyable to get through.

What it does:

✅ Create custom decks with just a few words describing what you want to learn ("History of the World Cup", "Why cement is everywhere", "Untranslatable feelings named in other languages")

✅ Explore hundreds of ready-made subjects

✅ Swipeable card decks instead of walls of text

✅ A Deep Dive behind every card for when you want to go deeper

✅ Available in 8 languages: English, Spanish, German, French, Brazilian Portuguese, Russian, Japanese, and Simplified Chinese

Perfect for:

🎓 People who miss learning something just because it is interesting

📱 Anyone trying to swap ten minutes of doomscrolling for something that leaves them with a sense of satisfaction

🧠 The "I have always wondered about..." crowd

🎁 The giveaway (open for the next 48 hours):

3 months of Erudity Premium, free. Full access to the whole app, normally $69.99/year.

To claim one:

1. Upvote this post so more curious minds can spot it
2. Comment below with something you've always wondered about but never got around to learning
3. DM me, and I'll send back your promo code. Starting the chat on your end actually gets the code to you faster, so do not be shy 🦉

To redeem: open the Play Store, tap your profile picture, tap "Payments & subscriptions", then "Redeem code", and paste in the code I send you. Small print: it redeems as a subscription, so if you would rather not keep it after the 3 months, just switch off auto-renew in your Play Store subscriptions and you will never be charged.

I would really love to see what you are all curious about, so do not be shy in the comments. And once you have had a play with it, if it made you smile even once, a rating or even a quick review on the Play Store makes a tiny team's day.

Thanks everyone 🖤

I wanted a task manager that was simple.

No account. No cloud requirement. No subscription pop-ups. No AI trying to manage my life.

Just a clean app that helps me remember things like buying groceries, calling my parents, paying bills, or keeping track of everyday tasks.

After trying countless apps, I realized I couldn't find exactly what I was looking for.

That eventually became Tasky.

My goal wasn't to build another productivity platform. I simply wanted an app that stayed out of the way while still offering the features I actually use every day.

Features:

✓ Works completely offline

✓ No account required

✓ Voice input

✓ Smart reminders

✓ Recurring tasks

✓ Subtasks

✓ Home screen widgets

✓ Material design with beautiful themes

✓ Tablet and landscape support

I'm finally at the point where I'm comfortable sharing it beyond friends and family, and I'd love to hear what other Android users think.

I'm not looking for praise. I'd much rather hear what frustrates you, what feels missing, or what you'd improve. Honest feedback is incredibly valuable at this stage.

As a small thank you, I'll send a Google Play redeem code that unlocks Tasky Premium for life to anyone who provides thoughtful feedback. Just leave a comment or send me a DM after you've tried it.

Google Play:

https://play.google.com/store/apps/details?id=com.cleanlabs.tasky

Whether you end up using Tasky or not, I'd still love to know what your ideal Android task manager looks like.

I created this app called OneLink Universal Remote which turns your phone into a powerful Bluetooth remote for PCs (Windows, Mac, Linux, Chromebook), TVs, projectors, and media devices. Unlike traditional Wi-Fi remotes, It uses Bluetooth HID technology. There is no server software to install and no additional hardware required. Your all-in-one control companion includes a full keyboard, a precision trackpad, an air mouse, media controls, and a customizable macro deck. It’s a Swiss Army knife for your digital devices.

I believe most of you will find it really useful.

Hi, sharing my app.

Diktafon is a voice recorder built around cassettes: each topic gets its own tape, memos land at its end, and the cassette plays as one continuous recording. Every memo is transcribed, every cassette summarised and titled; tap a word in the transcript and playback jumps there. Everything runs offline on the device (Whisper + a small LLM) — no account, no cloud, no analytics, no ads. Free and open source (MIT): https://github.com/jaromiru/diktafon

I built it because nothing quite fit how I use voice notes. Apps like WalkWrite or Notely Voice turn speech into text notes; here the recordings stay the main thing, with the text attached.

Honest caveats: models are downloaded once on first run (Wi-Fi recommended) and 4 GB RAM is recommended for the defaults. Quality is what on-device Whisper gives you — solid, not magic.

Fun fact: despite being a long-time programmer, I mostly vibe-coded it with Claude as an experiment — and it did as I expected: very well.

I use it daily and figured others might want it too. I'll be glad for any feedback!

Don't worry there is no catch because i want this app to be useful for me because i am using it too😂. You don't have to create an account and you can export your data if you want to change the device and import it there too. You can track your maximum weight each time too.

Key Features: Premium UI: Clean, frosted glass design with adaptive Light and Dark modes🌙

Smart Tracking: Easy workout scheduling, quick set/rep logging, and auto-generated progress charts 📈

100% Private: Entirely offline with built-in data backups and zero tracking 🛡️

Peerly is a free, ad-free offline messenger that works without mobile data or internet access. It uses Bluetooth and Wi-Fi Direct to connect nearby Android devices directly, making it useful at festivals, in remote areas, crowded venues, or during network outages. No account, phone number, or central server is required. I know there are already a few apps with a similar idea, but this type of communication is still not widely used. I think it is worth giving Peerly a try and seeing how useful offline messaging can be in real situations.

Link: https://play.google.com/store/apps/details?id=com.peerly.app

What it does: You describe a conversation you're dreading — telling someone no, asking a friend to pay you back, a boundary with family, something awkward at work — and Candor writes three ready-to-send versions of the message:

• 🫶 Warm — kind and gentle
• 🎯 Direct — clear and neutral
• 🧱 Firm — a hard line, still respectful
• 💵 Free Trial — Use it for 7 days without having to pay for it

Pick the one that sounds like you, tweak it, send it.

Key features:

• 6 categories: Saying No, Conflict, Money, Workplace, Relationships, Family
• Two input modes — Quick (free-text) or Guided (a few questions)
• 7 wallpaper themes, light + AMOLED dark mode
• No account, no sign-up — nothing stored on a server
• Native Kotlin + Jetpack Compose; AI runs through my own backend proxy (no keys in the app)

Why I built it: I'm the person who rewrites a text fifteen times before sending it — or never sends it. I wanted something that just hands me the words. This is my first app, self-taught, built solo over the last 7 months. Went live on Google Play last week.

Feedback I'm looking for: Does the tone of the three variations feel right? Is the Guided flow worth it or would you only use Quick? Anything in the UI that felt clunky?

Hi all! Excited to announce Mechanly - my most ambitious project yet.

Over the years I've built some Android firsts (IJP apps): Energy Ring, the battery indicator that wraps around punch-hole cameras; Access Dots, which brought camera and microphone privacy indicators to Android before they became a native feature; and CoverScreen Apps, along with several experiments pushing what cover screens on Flip phones could do. And now super excited to share with another firsts for Android, a super app - Mechanly!

Mechanly ^ _ ^

Mechanly lets you describe an App you wish existed or a Task you want your phone to handle.

For example:

Check my Gmail Spam folder every few hours. Find messages that may have been caught by mistake and let me move them back to my inbox.

Or,

Every weekday morning, compare my two routes to work. Notify me only when one saves more than ten minutes.

You don’t have to build a flowchart or connect a dozen blocks. Describe the result you want, review the access it needs, and save it.

Mechanly can create two kinds of experiences:

• Tasks work for you on demand or in the background. They can check something, process information, send a notification, or produce an interactive visual result.
• Apps give you a custom interface with its own storage, icon, and home-screen shortcut. An App can be a simple personal tool or stay connected to Tasks that keep its information updated.

Why Android-first?

A modern Android phone is already a powerful, always-connected computer that stays with you throughout the day.

However, many agent-style tools still depend on a desktop computer, server, or open browser window.

Mechanly is built around a different idea: your phone itself can be the home for your personal Apps and Tasks.

A Task can run while Mechanly is closed and the screen is off. When it finds something useful, it can notify you or open an interactive result directly on your phone.

You don’t need to leave a PC, Mac, or VPS running just to check a website, prepare a briefing, or watch for something important.

What Mechanly can do

• Run Tasks in the background Tasks can run on demand or on a schedule, including while Mechanly is closed and your phone’s screen is off.
• Work inside your logged-in browser Mechanly has a built-in browser. Sign in to a website once, and a Task can later use that same on-phone session. This is useful for information behind a login, especially when the website doesn’t provide a convenient API.
• Use app connectors Tasks can work with supported services such as Gmail and Google Calendar.
• Use Android notifications - with permission Mechanly can optionally read your phone’s notifications. This makes experiences such as notification triage and overnight summaries possible.
• Notify you only when something matters A Task doesn’t have to bother you after every run. It can notify you only when it finds an important email, a delayed delivery, a faster route, a price drop, or another condition you define.
• Produce interactive visual results A Task can return more than a sentence. Tapping its notification can open a visual briefing, workout, inbox, report, or another custom experience.
• Create Apps for your home screen A Mechanly App can have its own interface, storage, generated icon, and home-screen shortcut. It can be something small and personal that no developer would normally build as a standalone app.
• Connect Apps and Tasks An App can display information prepared by background Tasks. For example, a Task could check your orders periodically while an App presents them as a delivery and spending dashboard.
• Share and import creations Apps and Tasks can be shared through an import link. The person importing one can review the required access and connect their own accounts.

I am sharing few Tasks and Apps that I created on Mechanly for your inspiration below, but it's practically limitless, super excited to hear what you guys come up with or any unique use cases that you would like me to support!

Hello everyone!

My Android app was just approved!

It's called DrinkTick a simple drink tracker for water, coffee, tea, alcohol, and more. No typing: just tap a tile and it's logged. It features a progress ring showing how close you are to your daily goal, plus streaks, stats, and a heatmap (pro only) to track your consistency over time.

Everything works offline. No sign-up, no account, and nothing leaves your phone.

To celebrate the launch, I'm giving away 100 lifetime Pro codes! Unlocks all drink types, custom drinks, extra reminders, heatmaps, and backup/export, forever, with no subscription.

Promo codes are available (51 remaining)!

Google Play: https://play.google.com/store/apps/details?id=com.jaironlanda.drinktick

The promo will run from July 20 at 7:00 AM (GMT) until July 25 at 12:00 AM (GMT).

Thanks for reading, and I'm happy to answer any questions!

I've always wished Google Maps had a timeline that simply showed every drive I actually took.

Not the route it suggested.

The route I ended up driving.

So over the past few months I built DriveTrack.

It works by pairing with your car's Bluetooth once. After that, whenever your phone connects to your car, it automatically starts recording the trip, and stops when you disconnect. No buttons to press.

Some things it tracks:

• Full GPS route

• Distance, duration and average/max speed

• Moving vs stopped time

• Elevation changes

• Weekly, monthly and lifetime stats

• Favourite routes

• All data stays on your device

I originally built it just for myself because I enjoy driving and wanted a history of everywhere I'd been. It ended up becoming something other people found useful too.

I'd genuinely love to hear what features you'd want in an app like this or any feedback on the idea.

Play Store:

Hey everyone!

I've been building an Android launcher that replaces icons with "cheat code" gestures, and I'm looking for beta testers.

CheatCode Launcher is built around using combinations of gestures (up, down, left, right, tap) to create "cheat codes" that open apps, run shortcuts, tasker tasks, and pretty much anything else. The design direction is extreme minimalism with maximum speed. The more you use it, the more muscle memory you build.

Some key features:

• Assign gesture codes to open apps, shortcuts, run tasker tasks, control media and more
• After shortcuts: assign linked actions to a specific app that show up for a short time when you close it. For example, when closing the Camera app, you can have links appear for: Google Photos, Instagram, Lightroom, or whatever other apps or actions you want to appear.
• Highly customizable theming that can be saved, shared and imported.
• Auto-theme switching: Have the look and feel change based on what's happening on your device. Set a custom theme for specific days, dates, notifications, media playing, etc.

Most features are free with generous limits. Premium features are available, but anyone who provides constructive beta feedback is welcome to a lifetime promo code.

What I'm looking for:

• Different Android devices (especially OnePlus, Xiaomi, Motorola, tablets, and foldables)
• Feedback on usability
• Bugs and performance issues
• Feature suggestions

To test:

1. Join the following group: https://groups.google.com/g/cheatcode-launcher-beta
2. Become a tester: https://play.google.com/apps/testing/com.pantsninja.cheatcodelauncher

Thanks for taking a look! I'd really appreciate any feedback.

Hey all — built an Android app called WalkOrLose. You join a step challenge, put down a small entry commitment, and whoever actually hits their daily goals through the challenge splits the pot funded by the people who didn't finish. Right now the welcome challenge has a €100 pool split between everyone who completes it — good way to try it risk-free-ish since finishing gets you a share instead of just your money back. Built with Health Connect for step tracking and some anti-cheat checks so GPS-spoofers/bots can't game it. https://play.google.com/store/apps/details?id=com.walkorlose.app Happy to answer questions about how the tracking/verification works.

App Name: AR DrawKit

Every AR Drawing app has a premium gate for most resources, too many ads, or the price is too high. So, I built my own. Very few ads and a very low-priced plan with premium features that most of the apps are missing.

Link: https://play.google.com/store/apps/details?id=xyz.devnerd.ardrawingkit

How it Works:

1. Pick an image from the app / Gallery / Browse from the internet
2. Select how you want to draw (with camera or on screen)
3. Complete your drawing
4. If you are new, my app has over 200 step-by-step guided drawings.

Exclusive features:

Art Wall - for sharing your drawing

Community Drawing - People can share art for others to draw

P.S: I am constantly updating the app as my wife is using it daily to draw. As I have a real user in my home, so the features are and will be user-friendly.

If you want to try or want to share it with someone, please comment; I'll share a promo code with you.

I’m a dad, and like a lot of parents, I ended up with piles of drawings and school artwork that I didn’t want to throw away.

So I built Kid Art Museum — an Android app that lets parents save, frame, organize, and turn their children’s artwork into a digital museum and art book.

I’d really appreciate any honest feedback, especially from parents, teachers, or anyone who deals with lots of kids’ artwork.

Google Play:
https://play.google.com/store/apps/details?id=com.appasty.kidartmuseum

I’m also happy to give a few lifetime Pro promo codes to people who genuinely want to test it.

I love listening to music, but I wanted a simpler experience:
• Background playback without interruptions
• Synced lyrics while listening
• Music videos and audio in one place
• A lightweight Android experience

So I built SimpMusic.

I’m sharing it here because I’d love feedback from people who care about music apps:

• What features do you wish your music player had?
• What annoys you about existing music apps?
• What would make you switch?

Always looking for ways to make it better.

Title: Beave - Focus with Friends - Free

I have built a gamified focus app where you can block distracting apps or flip your phone face down to focus. you can focus together with your friends too and there is a leaderboard. the idea is that you collect sticks as a beaver to build dams on real-life river maps and focus. the more sticks you have, the more higher you rank in the leaderboard. it makes focusing fun and social.

I was frustrated with social and smartphone media addiction so I thought of making this app so other people who are facing the same problem can benefit from it.

Have you ever tried losing weight to better your future self, downloaded a calorie-tracking app, then quit altogether after a few weeks because it was too much of a hassle, or because it was too expensive? Your personal health and well-being shouldn't have to deal with all this.

As someone who's lost 65 lbs and is super into fitness, I find that tracking my calories and macros is an essential practice to lock in on my progress to further improve myself. But I had to go through this same struggle, painstakingly tracking every food and spending 5-10 minutes every day tracking everything I ate that day, consuming my life. Or on the flip-side, spending 12-15 dollars a month for the comfort of ease, draining my wallet. So I decided to change that.

I built an app called Macro-Fit, a calorie-tracking app that is designed around the ease of the user, completely free to use, with optional premium features for just $3 a month, a quarter of the price of the other brands. FIRST 100 USERS GET 1 YEAR FREE (DM me about your installation, and I'll give you premium access for a year, currently at 45 users so slots are filling up quickly!).

With Macro-Fit, I can now log my entire day in 15-30 seconds, making tracking effortless, so I can stay on top of my goals without having to slave over logging and tracking every day. If you guys are interested, here's everything Macro-Fit has to offer:

• Massive food-search database
• Manual food entry (enter custom calories and macros for a food)
• Customizable progress targets just for you
• Meal Creation to group multiple food items together and log alltogether
• A Library to save your favorite/most used foods to for quick logging
• Weekly & Monthly progress reports and charts
• PREMIUM (FREE FOR 1 YEAR FOR FIRST 100 USERS):
• Barcode scanning
• Nutrition Label Scanning
• Voice Add
• Recipe scanning for instant meal creations
• Online recipe URL pasting for instant meal creations

If you want to take your fitness to the next level without having to jump through hoops or burn a hole through your wallet, or if you just want to help a small developer, then join Macro-Fit today!

Google Play Store

I built FidgetDrop as a focused Android fidget app for quick tactile interactions without the ads, virtual currencies, accounts, and clutter found in many similar apps.

The app includes several interactive fidgets that use animation, touch input, haptics, sound, and device motion. I am continuing to improve the physics-based interactions, including fidgets that react to the phone’s gyroscope.

Current features:

• Multiple tactile and physics-based fidgets
• Haptic feedback and optional sound
• Gyroscope-controlled interactions
• Local activity and usage records
• No account required
• No ads
• Optional one-time Pro upgrade

I would appreciate feedback on a few specific areas:

1. Which fidget feels the most satisfying?
2. Which interactions feel repetitive or should be removed?
3. Do the haptics feel strong, weak, or inconsistent on your device?
4. Do the gyroscope-based interactions feel natural?
5. Is it immediately clear how each fidget should be used?
6. Are there any visual, performance, or accessibility issues on your phone?

Google Play: https://play.google.com/store/apps/dev?id=8067447984067693441

I am the developer, so technical feedback and bug reports are welcome. I would rather improve the strongest interactions than add dozens of low-quality variations.

What it is:

A calorie and food tracker for Android. All food logs, weight, and settings live in a local database on the device.

Why I built it:

A friend wanted a simple way to track what she eats for a weight-loss diet, and every popular option wanted an account or a subscription, or had a really convoluted setup just to get your calorie target.

It's also my first real solo app — built in Flutter, with AI help as a learning project.

Features:

- Calorie + macro tracking, with per-nutrient goals you can toggle (protein, carbs, sugar, fiber, fat, saturated fat, sodium, cholesterol).

- Barcode scanner via Open Food Facts — and if a product's data is missing or wrong, you can fix it or add it from the app, and the correction goes back to the open database.

- Recipes: build a meal from ingredients and it calculates the full nutrition.

- Weight tracking + optional BMI

- Starting with currently 285 whole foods preloaded with USDA values.

- Metric/imperial, dark mode, four themes.

- Works offline — the only network calls are the barcode lookup and the ad.

Monetisation: Free with a single banner ad. No subscription, no paywalled features, no IAP.

Link: https://play.google.com/store/apps/details?id=com.tomic.calorie_counter

Genuinely after feedback — it's new and first complete finished app of mine, so if something's clunky or broken I want to hear it.

Here are a few things that make HabitSet different:

- Flexible streaks that actually make sense

Track habits weekly or monthly (like 3x/week or 8x/month) without fake daily streak pressure.

- Your history stays intact

Changing a goal won’t automatically destroy your existing streaks and progress.

- No random streak losses

Time zones and DST are handled properly, so your progress stays reliable.

- Reminders that aren’t annoying

They stop once you complete a habit and return only if you undo it.

- Fast home screen widgets

Complete habits instantly without opening the app.

- Fully offline & privacy-first

No account, cloud sync, or data collection. Your data stays on your phone.

There’s also a compact layout for tracking many habits, plus lightweight stats that stay useful without becoming overwhelming.

Every review genuinely helps 🙏

Hey everyone, I am the developer of Omni.

Omni is an experimental Android agent that uses the Accessibility API to understand the current screen and complete tasks by tapping, typing, swiping, navigating, and opening apps.

I originally planned to release it as a regular app, but Google Play restrictions around general-purpose Accessibility automation made that difficult. Instead of abandoning it, I decided to open-source the complete project.

The repository includes:

• A native Kotlin Android app

• A self-hostable Elixir/Phoenix backend

• Support for Gemini, OpenAI, Anthropic, and Groq

• Optional Deepgram voice recognition

• A community build without Google sign-in or store billing

• Complete installation instructions

It is still alpha software and should not be used for banking, passwords, payments, or other sensitive tasks.

App Name: Upikd

What it does: Upikd ends the "where should we go?" argument. Everyone in your group swipes on nearby venues at the same time, and when you all land on the same place, that's your match.

Key Features:

• Real-time group sessions plus a solo mode for deciding on your own
• 16 venue types across moods like eating out, drinks, night out, family day, and get outside
• Spin Wheel and Crowd Has Spoken tie-breakers when the group can't agree

Goal: Launch
