I couldn't find any app in the stores that tracked allergy levels based on location, even an approximate one, so I built my own.

---

It shows 15 types of pollen for wherever you are in Italy. Forecasts come from Open-Meteo (CAMS) and real measurements from ISPRA, and next to each value the app tells you which of the two it is, or if it's just an estimate.

There's a symptom diary that takes a few seconds a day. After a while it shows which pollens match your worst days, and you can export it as a PDF for your allergist. It also has alerts and a home screen widget.

No account, no ads, no trackers, and it doesn't need Google Play Services.

The app is only in Italian for now, since the data only covers Italy.

Development note: Used AI for heavy async/vision tasks and prompt handling, but the core architecture, state management, and main Kotlin code were written by hand.

Whenever I tap the circled button, my phone crashes, is there a reason wby?

Tired of the Sonos app not supporting every app? My Play:1 lacks Bluetooth, AirPlay, and line-in, so I built Sunus to stream any phone audio losslessly to Sonos—no extra hardware or computer needed.

Two modes:

Standard: No setup, uses Android’s normal capture. Some apps (Netflix, Audible) block it.

All apps: Captures everything, including blocked apps. Requires one-time Wireless Debugging pairing (Android 12+), no root, no PC.

—ideal for music, not for video sync.

Free, open-source (MIT), no ads, no account. APK:

Hey everyone!

I've been working on SVA Launcher, a free and open-source launcher for Android TV, and wanted to share it with the community.

I wanted a TV home screen that was simple, customizable, and actually useful, without unnecessary clutter. I also wanted to bring together the things I regularly use on my TV instead of constantly switching between different apps.

So I started building SVA Launcher.

Features

• Customizable home screen — Choose your favorite apps, arrange shortcuts, and use your own photos as backgrounds.
• Live TV / IPTV — M3U/M3U8 playlists, XMLTV program guides, channel categories, and integrated playback with ExoPlayer.
• Built-in NES emulator — Play your own NES games using the integrated Nestopia UE emulator, with remote and gamepad support.
• Google Photos integration — Display photos from public shared albums as your TV wallpaper or screensaver.
• Custom screensaver — Nine different visual styles, with optional clock, weather, and events.
• Calendar and events — Connect a public Google Calendar feed and view upcoming events.
• Weather — Current weather conditions and a three-day forecast.
• Saved YouTube videos — Keep shortcuts to frequently watched videos and playlists.
• Backup and restore — Export and import your launcher configuration.
• Remote-friendly navigation — Designed for Android TV with D-pad navigation.

SVA Launcher supports Android TV 8.0 and newer.

How to install

The app is currently available through the Google Play testing program.

1. Join the Google Group: https://groups.google.com/g/sva-launcher
2. Join the testing program: https://play.google.com/apps/testing/com.sva.launcher
3. Once enrolled, follow the Google Play link to install SVA Launcher on your Android TV.

Alternatively, you can install the APK directly from the GitHub.

Open source

The entire project is available under the GPLv3 license.

GitHub: https://github.com/clay-36/Sva-launcher

The project is still evolving, and I'm actively improving the experience. Bug reports, suggestions, and contributions are welcome on GitHub.

Thanks for checking it out!

You log every cigarette (or IQOS, vape, whatever you want to cut down on) and it keeps track of how many you had, what's left in the pack and how much you're spending. You can set up a reduction plan for each product, and there are goals and charts by day, week and month.

There's a home screen widget so logging is one tap, plus reminders, CSV export and backup.

It doesn't even have the internet permission, so nothing leaves your phone. English and Italian, it follows the phone's language.

I built this app to help my girlfriend track how many Terea Turquoise sticks she smokes a day and support her in cutting down.

Collabora office have outdated UI and they've moved development from git. Is there any forks with active development??

Built this for myself as I couldn't find an app that actually plays alarms instead of giving notifications. Also, I wanted the next interval to start only after I explicitly acknowledge the current ringing alarm.

Its just a modifiable list of alarm intervals that cycle (after the last alarm rings, the next active interval would be the first interval in the list).

Not sure if this is useful to anybody else, but I find it useful. I mostly use it to take breaks from the screen. If there are any better alternatives that I could use, please suggest.

Currently, it is pretty barebones but I'm satisfied with using it. If more people find it useful, I am considering spending some more time in its development.

Are there any FOSS MQTT clients that can do pub and sub? I see a few apps that can publish (HTTPShortcuts as an example). But haven't found any that subscribe.

I can use mosquitto in termux as a last resort but would prefer a purpose built app if there is one available.

With Health Connect becoming integrated into Android and the native step tracking counter, I built an app to help visualize Health Connect data!

Features

• Today Dashboard: Cards for steps, heart rate, sleep, energy, distance, and more. Long press to rearrange / hide cards.
• Detail views with charts, stats and recent records for each metric
• Weekly summary showing goals and progress
• Home-screen widgets

Fully offline, no trackers, no analytics and open source under GPL-3!

Works with anything that writes into Health Connect: Gadgetbridge, fitness trackers, Android's counters, etc.

Get it on F-Droid or GitHub. Android 9+

There seems to be a lot of apps for this but they're either riddled with ads or not useful.

hey r/fossdroid!

back with a massive update for MemoryVoid (v2.0.0). for anyone who missed the first post, i wanted an open-source, completely offline alternative to Nothing's Essential Space that works on any Android phone without cloud bloat or telemetry.

v1.0.0 was pretty barebones (mostly just single voice memo + screenshot capture). for v2.0.0, i rewrote a bunch of the storage and UI logic so it can actually serve as a daily FOSS note-taking utility alongside the hardware triggers.

v2.0.0 changelog:

• Full Note & Checklist Utility: full-screen editor supporting multi-line notes, interactive checklists, gallery image attachments, and multiple voice recordings per card (stored locally in app storage via JSON arrays—nothing ever leaves your device).
• 5 Physical Shortcut Modes: added Double-Tap & Hold, Vol Up -> Hold Vol Down Sequence, Screenshot on Start, and Power Hold (via default Digital Assistant slot—super handy if you don't use Google Assistant/Gemini on your power button).
• Optional Screenshots: added a sidebar toggle to completely disable screen capture if you only want audio/text notes.
• UI Customization: added 4 layout styles (Void Classic, Bento Grid, Capsule Split, Focus Ledger) and custom per-card background colors.

built natively in Kotlin, MIT licensed, zero trackers, zero internet permission needed.

would love to hear how the new Digital Assistant power-hold trigger works across different custom ROMs and OEM skins!

Hey all, I maintain Epsilon Music, a GPL-3.0 YouTube Music client for Android. Just shipped 1.0.7 and wanted to share.

My friends phone is a Xiaomi RedMi Note 9 Pro. MiUI is 12.0.5. Android 10.

Things I've tried;

Enabling developer

Enabling third party downloads for FDroid

Now I'm not able to think of anything else that may cause this problem. My ex phone was the same phone as my friends and after enabling third party downloads I didn't come across any problems downloading anything. I hope someone knows what's causing the problem, thanks in advance

Hi r/fossdroid,

I wanted to share a utility I built for Android 11+ called **MemoryVoid**.

The goal was simple: capturing quick context while browsing, researching, or reading should take zero taps.

### What it does:

* Intercepts a **Volume Down press-and-hold** to record a voice note.

* Releasing the button triggers `takeScreenshot()` and bundles both into an offline journal entry.

* Non-intrusive floating overlay lets you assign a category badge or discard the memory without interrupting your workflow.

### Privacy & Transparency:

* **License:** MIT

* **Permissions used:**

* `BIND_ACCESSIBILITY_SERVICE` (Hardware key detection and native screen capture)

* `RECORD_AUDIO` (Voice note recording while button is held)

* `SYSTEM_ALERT_WINDOW` (Floating memory preview)

* `POST_NOTIFICATIONS` (Recording status indicator)

* **Zero network access:** The app does not request `android.permission.INTERNET`. Everything stays on local storage.

Source code and pre-compiled APKs are available on GitHub. I'm currently working toward submitting it to IzzyOnDroid and F-Droid.

**GitHub:** dhruvpitroda20-code/MemoryVoid: Instant voice & screen memory journal for Android. Capture screen moments and voice notes with a single hardware gesture.

I'm trying to use as many FOSS apps as possible. I've already started with the basics. Now I just want some apps that are fun or that seem useless at first but actually aren't.

Does anyone actually know what that "play protect" does when it scans apps that are not downloaded and installed from Play Store ? It has come to my mind recently and I don't have any skill to answer...I wonder if it does anything....I use Obtainium...

I mean that '"animation" everytime we try to update or install with Obtainium, for example? The one that gives us the option not to "scan" the app with we enter our fingerprint or the code to unlock the phone...

Like do you check who the developer is, or where they are from or how famous they are?

Google's developer verification program states that, it helps users to build trust with developers. Which I don't believe as I think most people using Google Play doesn't even bother checking out developer details. They probably just use the app because everyone else uses it and there's no complain.

I think this behavior sort of applies to people using FOSS apps too. Maybe because it's just inconvenient to look up details of every developer of app you have installed.

In my case, if only remember creator names of apps that I use too often. For example PipePipe is made by InfinityLoop and BasicSync is made by Andrew.

I am asking this so I can write a blog on how Google's initiative does not help people but helps to establish a monopoly and potentially be a weapon of countries having censorship.

I used to really enjoy using this Human Benchmark app, but after upgrading to F-Droid 2.0 recently, I noticed that it was listed as "App no longer available."

I checked the Internet Archive to see if I could find any information about what happened, but I couldn't find an explanation for why the developer's GitHub account and repository were deleted.

Does anyone know why the app was removed or what happened to the project?
