I’ve recently decided to switch out my Playstore apps for Open Source Apps as they’re usually Ad Free and much less bloated. Can we use this thread to help people find open source android apps?
I’ll start
K-9 mail, a great email alternative that let’s you have multiple users logged in
Red Moon - A customisable night light app which lets you adjust the colour and settings including Colour, opacity and Darkness
Swift Notes - Note taking app
Aard 2 - translator that takes you to wikidictionary
andOTP - offline OTP with easy option to encrypt your backup with your PGP key
AnyMemo - very nice flashcard app. Creating your own (with Tatoeba for example) is very easy
Carnet - simple notes app
FairMail - great mail app. IMO better than K-9
Feeder - RSS watcher
Ghost Commander - file manager. UI is a little bit clunky but much better than enything else
KeePassDX - password manager
Librera Reader - IMO the best PDF/epub/mobi reader there is
monocles translator - nice translator similar to DeepL
NewPipe - youtube and bandcamp
Ning - local network scanner
OCR
Odyssey Music Player
OpenCamera
OpenKeychain - PGP
OsmAnd~ - navigation and maps in general
CV Project - Mozilla projecton capturing voice recordings
QKSMS - for sms
RCX - cloud client
Shelter - the “work profile” manager
Simple Calendar - calendar with very nice widgets
Sky Map - you can point your phone in the direction of a star and see it annotated
Weather Widget - for the weather
WebMediaShare/WebApps - discontinued unfortunately, but it’s great at appifying an URL, so you don’t have to use official app
I use more, but these are the ones I think might be most interesting to others. I don’t know if all of these are absolutely 100% open source (and that depends on definition) but all of these are in F-droid.
