My banking app ಠ_ಠ

Bitwarden. Most people think that their application is open source, but more and more of their code has shifted from the GPL/AGPL licensed code to code in their SDK, which is under a proprietary license. This led to their new Android app being disqualified from being hosted in F-Droid repos.

Keyguard was supposed to be an open source Bitwarden client, but the dev chose to use a custom proprietary license, so that is source available as well.

Pedantic, but Google Messages' RCS. And it's all Google's fault because they are holding the API hostage, probably because they want to create familiarity with the app so that people don't switch once they finally open up.

Google Pay/Wallet

Right now tap and pay is completely and hopelessly corporate

Google Play Services

Dating apps.

We need an open source completely free dating app.

No paying for matches, no limits ...just they're in your town, you look at their photos, you can talk, anyone can block anyone.

A keyboard with swipe typing, multilingual autocorrect and speech to text support that actually works.

Other than that, my only proprietary apps are from commercial services I use and pay for (banking, Spotify, Carsharing and public transport). I'd love for them to become open source, but it's probably not ever gonna happen, cause they rely on verifying my identity.

There are so many. By usage however:

Smart Audiobook Player: None of the apps I tried had all the features in one, like reading my complex audiobooks folder structure and auto grouping the books based on that. Timer to pause audiobook that is automatically reset by moving the phone.

Maps: No foss solutions work better where I live than GMaps

YTMusic: So this is a tough one to beat because of the nature of the platform itself.

Notes: I am looking for a P2P syncable note app that can also have a web interface or atleast a Linux version of the App. Allows drawing your notes on an android phone or tablet using stylus, and other usual features. Can also use cloud storage as a backup or sync source. I know this one is a really tall order.

I'm not sure if this fits but here is mine:

I want to get away from Samsung but the "Sound Assistant" app let's me control the volume of every app, kind of like a mixer. Sometimes an app doesn't have a mute option, I can set the volume of that app to 0 without effecting the volume of whatever music I'm listening to.

I also like to listen to my local police scanner and music at the same time. I can set the volume of the scanner app low enough to not really bother the music but loud enough that if something happens I can still hear it and pause the music.

I can't believe Samsung and their app is the only way, but I haven't found an alternative.

Symfonium. There are plenty of music apps, and I've used a lot of them, but none combine the UX and functionality that Symfonium offers to anywhere near the same quality :/

Tasker: I haven't used it, but I've seen useful automations over the years from people online and I would probably use a good FOSS alternative.

Honestly, Google Keep notes. Trilium server runs as a UWA on Android but it's pretty ass. And things like Obsidian are way too much for something me and my (non-technical) SO use to share notes

File Manager Plus:

It connects to all my SFTP servers effortlessly, and it's an absolutely stellar file Manager.

JuiceSSH:

Manages all my SSH servers and identities, and has an extremely usable terminal. It's got extensions too.

Nova launcher.

I Haven't found one that works so well with KLWP or has good app drawer organization. I like having folders and tabs to split everything up. Having one big list of apps (70% I dont use often and another 10% bloat) isn't useful.

Whatsapp. I know signal, simplex, matrix, (a billion other things), etc exist that are much better, but where I live, no one uses them, for context, basically everyone, like if you have a phone, you use whatsapp, some government things even happen through whatsapp bots, when people say the word message here, they mean whatsapp. There are about 20-30% (among younger folks) who use telegram, but that is mostly for easier piracy, and larger file sharing (before whatsapp allowed 2 GiB, now they do it habitually). My mom has about a 1000 contacts, and less than 10 of them actually use signal (there are many more who signed up(there was another thing, basically when elon said "just use signal"))

At this point it is not worth getting everyone to switch, the best i have done, is just reducing the number people i communicate with (on whatsapp), and try to just meet in person

People have hit on most of them here, but here is another big one:

Fitness apps. Mainly calorie tracking, workout tracking and heart rate tracking

Health app

Sleep as Android

(No, gadget bridge is not a replacement for 99% of cases and doesn't even support the gold standard for heart rate tracking, polar H10)

For calorie tracking, the massive food databases required, barcode scanning, and crowd sourcing are generally not compatible with the open source community's privacy ideals. OpenNutriTracker has promise though!

For workout tracking, none of them have any device support and most of them are dead and abandoned. Not to mention heart rate zones, stats and training trends, etc... FitoTrack and Opentracks are good starts though.

And then a google fit alternative. Something that can integrate sleeping, workouts, heart rates, sensors, etc.. Data all in one aggregates place. It is a huge task and it makes sense that there is no open source alternative for it. Especially when the components aren't individually there to aggregate.

Tasker, because there's no alternative.

MiXplorer (file manager), because even if not counting the features that should be a different app, it's much better than material files.

OpenCamera is good, but could do better. But I'd say video editing is the biggest void.

Also, gesture typing keyboards are an empty niche of foss alternatives. HelioBoard requires loading some proprietary blob unfortunately.

I guess the most heavy machine learning use cases are not filled in.

Obsidian

Poweramp

There's nothing else out there that's really an equal, foss or not. The closest it gets is neutron, and that's a hot mess of an app.

It's the sound quality that's standout. It doesn't hurt that it's a decent player in every other way too, but even apps built for audiophiles don't match it in real use, in every situation.

None of the foss players are worth a damn sound wise; might as well use whatever comes with the device on that factor alone.

Bank clients. Taxi aggregator clients.

I would like to find alternative to Garmin app. It is bad if you don't want to use the cloud features, also you can't plan routes without internet connection like wtf that's the only reason I bought it for.

I really need a libreoffice calc on my android phone. Not just opening (where currently only Microsoft Excel on Android works for me) but also editing and saving to my connected nextcloud (where I have also problems with Excel)
