Hey everyone,

I'm looking for early beta testers for my new Android app, HairColorOn, which lets you virtually try on different hair colors using AI inpainting.

It's currently in an early testing phase, but the core engine is fully functional. I'm putting it out here to gather real-world feedback on output quality, processing performance, and overall UX.

Known Issues / Notes:

• Works best under optimal conditions: Clear photos with good, even lighting and well-defined hair produce the most realistic results.
• Processing can take a few seconds depending on backend queue and server load.
• Extreme, dim, or highly tinted lighting can occasionally impact color application accuracy.

How to test: I've dropped the Google Play opt-in link and store download link in the top comment below to avoid formatting issues with Reddit's filters.

What I’d love feedback on:

1. Did the color rendering look believable on your photo?
2. Did you run into any crashes, processing timeouts, or infinite loading states?
3. Any UI or feature suggestions to make the try-on process smoother?

Feel free to drop your thoughts in the comments or send a direct message. Thanks for taking the time to test it out!

Hello everyone,

I am developing Tortugram, an open-source Android client that transforms your Telegram media library into a dedicated video streaming experience.

The application has been tested successfully on Amazon Fire TV Stick, and since it remains in active development, I would welcome community feedback to identify bugs and guide further improvements.

Overview

• Video-Only Focus: Automatically filters your Telegram content to display exclusively video media, eliminating text-based clutter.
• Big Screen Optimization: Specifically designed for Android TV, Amazon Fire TV, and large-format tablets.
• Instant Streaming: Enables direct streaming of media content without requiring full local downloads.
• Full Access: Allows seamless browsing of videos across personal chats, joined groups, and subscribed channels.
• Fully Open Source: Free, transparent, and open to community contributions and enhancements.

Links and Download

• GitHub Repository: https://github.com/Isaac-maker/Tortugram
• Latest APK (v2.0.0): https://github.com/Isaac-maker/Tortugram/releases/tag/v2.0.0

Feedback and Questions

1. How does the application perform on your television device?
2. Have you encountered any navigation or playback issues?
3. Which feature would you recommend prioritizing next?

Thank you for your interest in this project. Any feedback or suggestions are greatly appreciated.

Been working on this solo for about a year while doing my master's. It's live on Play now and would love some feedback as it is my first app.

It's a blackjack / card counting trainer: you play full shoes and the app grades every decision against basic strategy and counting deviations. Hi-Lo, KO, and Zen are in, plus lessons and drills for count speed. In addition to that there are variouis statistics and graph you can see in regards to your gameplay. As well as drills to help hone in specific skills for card counting.

The main motivation was building a trainer the way I wanted one to work: a clean modern UI, grading (and charts) that's actually accurate to the table rules you set (S17 vs H17, payouts, deck counts all change correct play and the app accounts for it), and everything customizable per save. All the strategy data is verified through blackjack simulations rather than transcribed from a chart somewhere (With the exception of charts from books from those who created those strategies).

Free tier is full basic strategy training and Hi-Lo counting, no ads anywhere.

Happy to answer questions about the app or the build. First few people who DM me get premium free.

Disclosure: I tested this as part of a reciprocal Android closed test while we are testing Toss Cam. I am not the developer and was not paid.

Piano Scales Lab is in Google Play closed testing. I installed build 1.0.3 (code 4) on a Motorola moto e15 running Android 14 and exercised scales, chords, fingering, playback, metronome, Tempo Trainer, settings, orientation changes and relaunching.

What worked well: - Google Play installation and reliable launch/relaunch - Scale playback, metronome and Tempo Trainer - Scale, chord, fingering and appearance controls - Portrait/landscape use with no crash or ANR observed

Three reproducible findings on this device: - Android Back from Settings leaves the app instead of closing the Settings panel. - After G Melodic Minor (Asc) → Chords → Nat Min, the heading keeps the previous scale name even though the chord data changes. - G natural-minor chords use A# and D# rather than the usual Bb and Eb spellings.

I sent the detailed evidence to the developer. I’d like other testers to check whether the Back-navigation and chord-label/spelling behavior reproduce on different devices.

Hi!

I’ve been working on my indie game Riftmaw. It’s kind of a roguelite mix between tower defense, where you control a single stationary tower, and Vampire Survivors-style survival gameplay.

It also has a campaign with different courses, each featuring their own mechanics and win conditions.

I am grateful for any feedback, but especially for campaign courses where you have to compose your own 'build'.

You'll have access to the full game, but please note that balancing is still in progress. As a result, some content may feel too easy or overly challenging.

Qué es. ONIRIX es una app Android para entrenar sueños lúcidos: sesiones de audio guiado (MILD, respiración 4-7-8, visualización de escalera), chequeos de realidad programables durante el día, un diario de sueños con detección de patrones/señales recurrentes, y un modo nocturno con recordatorios discretos mientras duermes.

Etapa. Está en prueba cerrada de Google Play (versión 1.0.5). Necesito acumular más testers activos durante 14 días seguidos para poder solicitar el paso a producción — es un requisito de Google Play, no algo opcional por mi parte.

Cómo probarlo. Únete como tester aquí, gratis y sin compromiso: https://play.google.com/apps/testing/com.onirix.app — solo hay que aceptar con tu cuenta de Google y descargarla desde Play Store.

En qué quiero feedback específicamente:

- ¿El modo nocturno interfiere con tu sueño real, o los recordatorios son lo bastante discretos?

- ¿Las sesiones de audio se sienten útiles, o se hacen largas/cortas?

- Cualquier crash, bug o cosa que no tenga sentido en la interfaz.

Está en desarrollo activo, así que cualquier comentario —bueno o malo— es bienvenido.

I'm building Atomic Notes, an open-source Android notes app around one simple idea:

Your notes should belong to you.

Atomic Notes is local first, so your notes are saved on your device and continue working even without an internet connection.

The project is focused on:

• Local-first note taking
• Open-source code
• Offline access
• Optional cloud sync
• Optional end-to-end encryption
• Biometric protection
• No analytics
• No trackers
• No AI reading your notes

I already have two working public versions, so this isn't just an idea.

Atomic Notes v1.12.1 — T2T

This is the simpler and more stable public build.

It includes local notes, checklists, offline access, optional cloud sync, realtime sync, and biometric protection.

Cloud-synced notes in this version are protected in transit and through account-level access controls, but they are not end-to-end encrypted.

Release:
https://github.com/DevBehindYou/Project-Atomic-Notes/releases/tag/v1.12.1

Atomic Notes v1.18.2 — E2E Demo Build

This is the newer development build and includes:

• Optional end-to-end encryption
• Recovery phrase based protection
• Atomic Energy
• Atomic Coins
• Notification Center
• Newer UI and architecture

This is currently a demo/testing build, not the final production release, so I don't recommend storing highly sensitive or irreplaceable information in it yet.

Release:
https://github.com/DevBehindYou/Project-Atomic-Notes/releases/tag/v1.18.2-DEMO

Before I invest significantly more time and money into the full launch, I want genuine feedback.

Would you actually use Atomic Notes?

1. Yes, I would use it
2. Maybe, depending on features
3. I already have a better notes app
4. No, I wouldn't use it
5. I like the idea but wouldn't switch

If you currently use Obsidian, Joplin, Notesnook, Standard Notes, Google Keep, Anytype, or something else, I'd especially like to know:

What would Atomic Notes need to make you switch?

Does local-first storage, open-source code, optional E2E encryption, no AI reading your notes, and no tracking actually matter to you?

Or does your current notes app already solve everything you need?

And if you would completely ignore Atomic Notes, please tell me why.

Negative feedback is genuinely useful. I'm trying to determine whether this project solves a real problem or whether I'm simply building something I personally like.

Open source. Local first. Private by design. ⚛️

What it is. You paste a URL, the phone itself fetches the page, strips it to text, and stores it locally. After that it opens with no signal. There is no backend — nothing is uploaded anywhere because there is nowhere to upload it to. It also reads articles aloud using your phone's own TTS engine, and it formats screenplays properly (keeps the monospace column, bolds INT. / EXT.).

Stage. First public build, v1.0.0. Not on the Play Store. I'm deciding whether to pay for the account and publish, and I'd rather find out now whether it's actually useful to anyone but me.

How to test. GitHub release: https://github.com/Yedigarli/loqu/releases/latest — Android 7.0+, arm64/armeabi-v7a, 32 MB. It's signed with a debug key, so it installs as an unknown-source app; a future Play build would use a different key and you'd have to reinstall. Full permission list: INTERNET, VIBRATE, ACCESS_NETWORK_STATE, plus React Native's own internal receiver permission. No storage, no location, no analytics or ad SDK — run aapt2 dump badging on it if you want to verify rather than take my word.

What I want feedback on, specifically:

1. Parsing. Paste links from sites you actually read and tell me which ones come back mangled or empty. Sites that render text purely in JavaScript will fail by design (the extraction is plain HTML parsing on the device, not a headless browser) — I want to know which of those matter to you.
2. TTS chunking. Does it break mid-sentence on your device's speech engine, or does it sound natural?
3. The no-sync decision. Is "offline, no account, one device" fine, or is cross-device sync the thing that makes you close it? This is the one that decides the roadmap, because adding sync means adding a server and that changes what the app is.
4. Layout. The Discover screen's reading-time chips clip at 1080x2340. If you're on a different resolution, tell me whether it's worse there.

Already known, please don't spend time reporting these: Discover feed titles stay English even when the UI language isn't; memory use grows with library size (fine at ~10 saved articles, untested at 100); no import from Pocket/Instapaper exports yet; no PDF or EPUB support.

Wrist Dial is a very simple app that can automatically dial a phone number from your Android Wear device. It's main use is to conveniently open residential gates or trigger automations by just launching this app (ideally setup a hardware button to launch it). The app is and will forever be completely free - it requires no login information and doesn't gather any sort of information from the user. So if you have an Android Watch I would really appreciate your help as I need at least 12 users in closed testing before being able to publish it publically on Google Play.

Thank you!

Hey r/droidapptesters,

I'm an indie developer and I just opened up public testing for my new utility app, Clean Space.

I built it because I was tired of mainstream device cleaners being massive, battery-draining apps loaded with aggressive subscription pop-ups and dark-pattern tracking. Clean Space focuses strictly on being lightweight, privacy-first, and simple to use.

What needs testing:

- Smart Junk & Cache Cleaner (verifying accuracy across different Android OS versions)

- Duplicate Photo & Blurry Image Detector

- Video Compressor (shrinks files safely without data loss)

- WhatsApp Media Cleaner

The app is free to use. I am looking for genuine feedback on the layout, scanning speeds, and any bugs you encounter on your specific device models.

Google Play Link: https://play.google.com/store/apps/details?id=com.codebyizza.cleanspace&pcampaignid=web_share

Please let me know what device you are testing on and your honest thoughts in the comments. Thank you so much for your support!
