June 13, 2026 - There are many open source music players I can point you toward. I used Auxio for years, and I've since been quite impressed by Symphony, but Lotus is my current go-to. This deceptively simple app fully embraces Android's Material 3 Expressive design language, offering large buttons and plenty of white space.

r/opensource on Reddit: Essential Open Source Android Apps?
April 23, 2025 -

Hi, I'm new of r/opensource and I'm curious to hear from the community about open source Android apps that you've discovered (perhaps not available on the Play Store) that have become absolutely indispensable to your daily life. Which FOSS Android apps have reached that "can't live without them" level for you? What makes them so essential? I'm not talking about cracks or mods of Spotify/youtube ecc

Since you are new to it: it starts with the opensource (and it has more) playstore called F-Droid. Apps: Newpipe: Youtube KDE Connect: connect various devices, share url's, files, notifications, and so on Syncthing-Fork: Sync files and folders across devices (this and KDE make a cloudless multi-device life possible for me) KeepassDX : Password store and more Compass DuckDuckGo Foss Browser Privacy Browser (yes, I use a lot of browsers; beyond those mentioned here too. A browser with a custom homepage is almost like an app for that site, but with much better privacy management!) FlorisBoard: Keyboard Fossify Gallery (an updated fork of Simple Gallery) G-Droid (F-Droid client with some stars) Imagepipe: Remove image metadata Liberia Reader: PDF reader, and many more formats. LocalSend: File sharing (at times, KDE and Syncthing have issues, so this is a good simple backup; also for devices where you might not want to put those big-guns) TrackerControl: Firewall with good configs - Worth a look for anyone serious about privacy (Netguard with more configs) URLCheck: Fantastic url stripper to remove trackers. Has automation too (though needs some json knowledge) Signal Messenger SimplyTranslate Mobile: Frontend for Google Translate VLC Media player The list could go on, but those are the better ones, I thought. Look up F-Droid, there is a big world in there. Edit: Minor improvements (descriptions etc)
