KineStop - After Apple announcef Motion Cues, I went looking on Android because I cannot use my devices in a moving vehicle. KineStop is all I found. I went ahead and bought it because it helps (doesn't completely get rid of motion sickness). I would gladly switch to an open source alternative if one were available.

Make an Android app for Redlib please :)

I can't find an equivalent replacement for Musicolet. There are plenty of open source music players out there for Android that just don't have the little features that Musicolet does. Such as multiple queues, lyric editing, metadata editing, format conversions, stop after the track finishes, easily reorder songs and clear queues, etc.

A delivery tracking app would be great, ideally with Widgets and Material You. On iOS I used to use Deliveries or ParcelTrack, but after switching to Android and primarily using open source software, I couldn't find a good alternative.

I don't use it much since I've already got it active on the apps I wanted it for, but on Samsung's Galaxy Store there is an app I've never found an alternative to anywhere from my limited searching: Sound Assistant.

On desktop/laptop, turning off individual app/program sounds is super easy, but this is literally the only app I've ever seen that allows you to turn off the sound for individual apps on android. Don't know if other versions of android from other brands or android 14 has that feature natively, but it's a feature I wish was native to all versions of android regardless of which large brand has made their own alterations to android.

A minor problem, though, as I assume most people probably don't give a rats ass about this.

I was going to write "a decent comic reader", but I've recently discovered Kotatsu and it has literally changed my life.

The Transit app, used for bus/train route info and buying tickets. I imagine the ticket buying part would be difficult to OS, but I just want the live transit routing info. A few apps exist for other cities, but not mine. Worst part is Transit relies on Google Maps.

Any image/video editor in Android. I've been trying Image Toolbox, but sometimes it doesn't work or crashes :(

Fitbod, a fitness app that monitored my progress and health data and auto generated appropriate workouts taking muscle group fatigue into consideration

I want to crop screenshots easily :(

"Pixels" mood tracker. I love it but I also love self-hosting all my services.

Mixplorer ?

I don't have any idea of how conplicated it would be, but a phone app would be a nice option. The stock dialer that comes with FOSS ROMs is OK functionally, but visually looks like it was from 2010. Plus it's not available through F-droid or other open source app store. Koler is the only serious dialer alternative I've seen, and while it looks nice it has always been super buggy.

If you're interested in something that doesn't even exist, and should be more-or-less straightforward:

Music/podcast app that will accept VST plugins (there are many FOSS ones, as well as non-FOSS ones) so that we can compress/limit the sound range on podcasts while in the car. Or even a built-in compressor/limiter that's based on FOSS compressors.

I was listening to a hysterical podcast episode between three people, but one of mics was way louder than the other two. I had to take it into Pro Tools and fix it myself before listening to it.

There are apps that allow EQ, but none that do actual compression, from what I can tell.

I can't wake up or a similar app.

I would've wanted an alarm clock app with 'tasks' you need to do before turning it off.

A lightweight office suit

Something that comes up a lot but probably can't be made open source is a wallet app. But if we ignore the payments part, Google wallet has some really nice features when dealing with plane tickets which I'd love to see in a standalone open source app.

Would like to get an effective metadata eraser, this one is pretty good https://f-droid.org/packages/com.jarsilio.android.scrambledeggsif/ but cannot saved to device, that's really awful... If you could get something as strong as this and saved it to device that would be pretty nice

Xplore file browser

It's trivial to replace the independent pieces of xplore, but it has so many features in one app that I just can't let it go. It's got dual pane file browsing, disk usage chart, smb, ftp, and many other cloud storage connections. It also handles many types of compression.

It's become my main offline music player as well, because it has the simple ability to shuffle a folder of music, which is all I really need.

It can also view installed apps, export them to apk, and view and modify appdata (as non root!).
