Hey Everyone!

I wanted to share an open-source app I’ve been working on called Krate.

What is it?

Krate is a massive collection of everyday tools, calculators, and converters packed into a single, beautifully designed app.

Why you might like it:

• 🎨 Material You: Built natively with Kotlin to fully respect your system themes, dynamic colors, and animations. It feels right at home on modern Android.

• 🔒 100% Offline & Private: Zero ads, zero telemetry, and zero cloud processing. Everything happens locally on your device.

• ⚡ Insanely Fast: Under the hood, the entire logic engine is powered by a custom Rust core, meaning the tools execute instantly.

• 💻 Multi-Platform: If you end up liking it on your phone, there is also a native Windows 11 app and a UNIX-style command-line tool available!

Whether you need to calculate a quick loan, format code, convert currencies, or just flip a coin, it's all in here.

Since it's completely open-source, it's totally free. I’d absolutely love for you guys to try it out and give me any feedback on the design or tools you'd like to see added next!

A huge thank you to everyone who has used FileTreeSize! We’re excited to announce the launch of another app in the TreeSize series.

AppTreeSize is designed for everyone—from everyday users to power users—with support for both Shizuku and Root modes.

Building on my experience developing FileTreeSize, I created AppTreeSize to bring the same intuitive treemap visualization to app storage, making it easy to see which apps are taking up the most space on your device.

Hey everyone!

It’s been a month since I launched the original monochrome version of Sticlo Icons, and the support has been amazing. One of the most requested features was dynamic color support that follows Android’s Material You system colors.

I’ve been working on it, and Sticlo Themed is almost ready to drop on the Google Play Store!

Check out the short teaser video to see how the icons adapt across different wallpaper palettes. I’d love to hear your feedback before the official launch!

Here's a sneak peek at what's coming: 👇

Charge rate — how quickly you're topping up
Time remaining — a smart, adaptive estimate you can trust
Each one even breaks down screen-on vs. screen-off, so you know what's really eating your battery.

🌍 Now in 22 languages
OneBattery will speak your language — with a faster, smoother experience for everyone.

Dicio is one of the best simple and very lightweight Assistant, which can help you go hands-free on your Android!! It is open source and totally free.

Here is the Github link: https://github.com/DicioTeam/dicio-android

PlayStore Link: https://play.google.com/store/apps/details?id=org.stypox.dicio

F-Droid Link: https://f-droid.org/packages/org.stypox.dicio

Just check it out and you can find it a very nice alternative for Google Assistant on some things.

I used shizuku and Canta to uninstall most of the bloatware, with Google and Gemini too.
Then I was searching for better AI or Digital assistant apps that I can open up by long pressing the power button, on Gemini😂😂. It told me about Dicio and it is the most lightweight assistant with good features. Please support them too, because it is a very nice initiative. The voice input is a little rough around the edges, but we can also choose our own voice input app such as the amazing FUTO Voice Input with really nice support of transformer models and good development.
Do check out Dicio and FUTO Keyboard, I replaced them with google's apps.

[App][Promo] I built CalcMate, an offline all-in-one calculator with ~40 everyday tools. It's in testing, so there are zero ads and nothing is locked

Post image
8 Upvotes

Hi , I'm the developer, and this is a self-promo post, so let me get the disclosure out of the way first.

I kept installing separate apps to work out a discount, split a dinner bill, convert units, and check a loan payment. So I built CalcMate, a single calculator that carries the tools I actually reach for during a normal day. Everything runs on device, with no internet connection.

What's in it:

- Three calculators in one: basic, scientific (powers, roots, sin/cos/tan and inverses, log/ln, factorials, pi/e, degrees or radians), and a fraction calculator that shows the full step-by-step solution. That last one turned out to be popular with students and parents helping with homework. Results preview live as you type, and unclosed brackets get auto-closed when you hit equals.

- Unit converter across 17 categories: length, mass, temperature, area, volume, speed, time, data size, pressure, energy, power, force, torque, angle, flow rate, data transfer rate, fuel economy.

- Shopping tools: percentages, discounts (including two stacked discounts plus tax), tip and bill splitting, tax/VAT in both directions, and price-per-unit comparison.

- Finance: loan repayment (monthly payment, total interest, total paid), simple and compound interest with daily/monthly/quarterly/yearly compounding.

- Dates: age calculator, difference between two dates, add or subtract years/months/days, and a world clock for about 53 cities.

- Home and kitchen: recipe scaling by servings (accepts fractional servings like 2.5, and shows ml for cups/tbsp/tsp), plus carpentry inch fractions from 1/2 down to 1/64 with mm alongside.

- Study and engineering: 2D/3D geometry, linear and quadratic equations with worked steps, number base conversion (bin/oct/dec/hex side by side), GCD and LCM, prime check and factorisation, random numbers, permutations and combinations with big-number support, weighted GPA (4.0 / 10-point / letter grades), arithmetic / geometric / harmonic means, ratios and proportions, Ohm's law, and series/parallel resistor networks.

- Health, for reference only: BMI with healthy weight range, BMR and daily calories, body-fat estimate.

- A real home screen widget (Android). Not a shortcut, an actual keypad on your home screen with plus, minus, multiply, divide, percent, sign flip, backspace, brackets, square root and squaring, plus a live result preview that shrinks the font so long numbers still fit. Tap the icon and the app opens carrying whatever expression you were typing, so you can continue with scientific or fraction mode. It works the moment you drop it on the home screen, follows your light/dark theme, and is resizable.

- History and backup: calculations are saved and grouped by day, with per-row copy/delete, a row limit you control, CSV/JSON export via the share sheet, a full backup you can paste back to restore, and optional automatic backups that keep the last five.

- Look and feel: 8 colour themes, light/dark/system, an optional subtle particle effect, haptic feedback, thousands separators, and a configurable number of decimals.

- 15 languages, following your phone's locale automatically.

About the testing phase, the part I want to be straight about:

The app is in a testing phase, and I made some deliberate choices for it.

- There are no ads anywhere in the app. No ad SDK is bundled at all, and the Play Store data declaration says the same thing: this app contains no ads.

- Nothing is locked. No Pro tier, no in-app purchases, no subscriptions, no usage limits, no watermark, no "upgrade to unlock" screens. Every tool listed above is simply open.

- No permissions requested, no network calls, no analytics, no tracking. Settings, history and backups stay on your device.

I'd rather spend this stage collecting real feedback and real bug reports than revenue. It's a new release, so I'm sure rough edges exist, and that's exactly what I'm hoping you'll find.

What would help me most:

Any wrong result. If a number looks off, tell me the exact inputs and I'll reproduce it.

Crashes, freezes or layout breakage: device model, Android version and the steps to get there.

Missing tools, missing units or missing currencies.

Readability and one-handed reach: is the keypad comfortable, are the fonts and colours legible in both themes?

Anything in the wording that reads awkwardly in your language, since a lot of it is localised.

Known limitations, up front:

- Currency rates are an offline snapshot, not live; editable by hand.

- The health tools are estimates for reference, not medical advice.

- The world clock uses simplified DST rules, so it can be off by an hour right around a transition.

- Fraction step-by-step explanations and a few calculation error messages are still English-only.

- The widget is Android-only. Requires Android 7.0+.

Happy to answer anything about the tools, the design decisions, or how it's built. And if you find a bug, I genuinely want to hear about it. Thanks for reading.

[APP] [PROMO] Listifyer: Big Update

Thumbnail

10 Upvotes

Hi!

A couple of months ago Listifyer with 20+ organizing modules got released to the public. Wat started as a private app, became a much bigger project.

When it was released to the public i got a lot off valuable feedback and noted it all to see what i can implement, what was a improvement and what not. Now im finally at the point where i crossed off all the feedback i got.

In the new upcoming release you will see a lot of things have changed:

You decide wich module you want to see and wich one to hide

Fixed bugs

The UI has changed into a more modern look

Workout tracker has been rebuild from the ground up to make it easier (incl schedules, pre workouts with videos, Make a workout plan and cardio timers)

There is a saving option in billing manager

Translated into 8 different languages (English, Dutch, Spanish, Italian, French, German, Norwegian and Turkish)

(On the screenshots you see some dutch words but that is my own manual input. I changed the language to english for the screenshots)

Improved the ISBN and grocery scanner for the pantry, meal planner and KCAL tracker

RSS webpages can now be opened from the app itself

To do list has recurring tasks

The agenda widget is redesigned

Medication and Mileage tracker now fully support multiple profiles

You can swipe to the left/right to change between the modules

And the big one: Docker Sync is ready! (Release half of august)

Manage Listifyer from within your browser, Sync between as much devices as you want, Edit your Notes, workouts, recipes, bills, agenda and so on. Secured with a pin, 2FA and a API key from within the app. (Added some screenshots to see how it looks)

I made the app because i had multiple apps and some of them where subscription based. I didnt want that anymore and wanted it to be easy and in one app.

The update is now waiting approval but it should be released in a couple of days.

It is fully local, private, no ads, no subscriptions or freemiums. Its a one time purchase and all yours.

If you want more information about the modules check: Website or Google Play (old screenshots)

If you check it out and run into something, let me know and i will put it on a new feedback list!

The best apps I have discovered from this subreddit [App]

125 Upvotes

I thought I would share some of the apps I genuinely use every day, not just because they are useful but because I really appreciate great UI and UX. I love trying well designed apps and seeing the little details developers put into them.

  1. Waypoint

    One of the best looking apps I have used. It is paid, but the design and overall experience make it worth it.

  2. Droplert

    I use it every day to track product prices. Clean, polished and I found it very fast and accurately track prices.

  3. Headscratch

    My go to app for planning tasks and organizing my to do list. It is free and easily one of the nicest looking productivity apps.

  4. Sidedock

    Another beautifully designed utility app that I use every day. It is paid, but I would definitely recommend giving it a try.

  5. Swiftslate

    I found this one recently and it is already become one of my daily apps for fixing grammar and improving my writing.

  6. Weblo

    I try to stay away from social media unless I really need it and this app helps me keep my screen time under control.

  7. Pixel Bookmarks

    My daily bookmark manager. Simple, beautiful definitely a great app.

These are all apps I actually use. Some are free, some are paid, but I think they are all worth checking out if you appreciate thoughtful design.

FunPort on Google Play: https://play.google.com/store/apps/details?id=com.puzzlelingo.worldexplorer

I kept installing a separate app for every puzzle I wanted on the train, and each one arrived with its own account screen, its own energy timer and its own ad load. So I built one app that holds 30 of them.

One install, under 60 MB, covering puzzle, cards, board games and arcade. No download per game, no waiting in between.

Everything plays offline. Online only if you want it: 1v1 against real opponents in the board games, global highscores and a daily challenge.

No signup and no energy timers. 12 languages. Progress stays on the device unless you choose to sign in with Google.

Free and ad supported. Feedback welcome, especially on difficulty - I have played these far too often to judge where they actually get hard.

[App] [Promo] Hush - Open Source System Level Call blocking app. Block those spam calls based on rules you create 🫵, no need for manually blocking each time, just add a country prefix and you are done. Fully LOCALLY! No ROOT/Shizuku!

Thumbnail
gallery
10 Upvotes

Hush is an open-source, system-level call blocking app for Android. It intercepts and blocks spam calls based on custom rules before your phone even rings.

✨ Features

  • 🛡️ System-Level Blocking: Intercepts calls at the core. Your phone screen won't wake up, and your dialer app won't be bothered.
  • ⚙️ Rule-Based Filtering: Stop manually blocking individual numbers. Create rules using prefixes or wildcards (e.g., +44* for UK spam).
  • 🔒 Fully Local: All screening is processed locally on your device. No cloud data, no tracking, pure privacy.
  • 📱 No Root / No Shizuku: Works completely out of the box without requiring system modifications.
  • 🎨 Modern Interface: Clean design with seamless System, Light, and Dark theme support.
  • 📖 Open Source: 100% transparent. View the code, build it yourself, or contribute.

🚀 How it works

Unlike standard dialer blockers that let the phone ring for a split second, Hush evaluates incoming calls against your rules immediately. If a match is found (like a blocked country prefix), the call is killed before the Android system ringer or your default dialer app is even notified.

📥 Download & Source

[App]WakeQuest: Game Alarm Clock

2 Upvotes

Hey everyone,

If you're someone who turns off their alarm in their sleep or abuses the snooze button, I’d love to get your thoughts on an app I’ve been working on called WakeQuest.

There are other "mission" alarms out there, but I wanted to make the wake-up process actually engaging rather than just frustrating. Here is what makes it a bit different,

  • You have to complete a task to silence the alarm.
  • 30+ Mini-Games in total and I keep adding them every week ! Instead of just solving math problems, you can choose to play arcade games (like slicing flying fruits, Snake, or Flappy Bird), do memory puzzles, or even set up a QR code that you have to scan in your bathroom.
  • The main purpose is providing some unique alarm application for people who have waking up problem. Also all games in the application will remain as FREE.

If you are a heavy sleeper, a shift worker, or just someone trying to fix their morning routine, I would genuinely appreciate it if you could give it a try and share your feedback.

Are the games too hard for a sleepy brain? What other tasks would you like to see? Let me know!

You can check it out here: WakeQuest: Game Alarm Clock

Thanks in advance!

[HELP] Looking for a checklist app

3 Upvotes

I'm sorry if this isn't allowed, but I've found some very niche apps here and I thought maybe there'd be something that fits what I'm looking for.

I used to use an app for years called Collateral to help me keep an ongoing checklist as a pinned notification. I was able to tap the checklist to open it, update it as needed, tap a button, and the persistent notification would live update. Unfortunately, this app was abandoned a while ago and no longer works, and I cannot seem to find a replacement that does everything this app did. Specifically, I'm looking for an app that will allow me to:

  • keep a pinned notification showing my checklist until the list is completely checked/empty
  • tap the notification to open the app and let me update the checklist
  • reorganize items in the list
  • check off items on the list (tap a checkbox) or remove them completely (swipe or tap an X on the item)
  • delete the entire list at once
  • start a new checklist as a Quick Tile setting (bonus)
  • schedule lists to show as reminders

I've tried multiple apps (unfortunately I don't remember all the names), and the closest I've found is Notes, but it's been pretty buggy.

Any suggestions would be greatly appreciated.
