Material-You-app-list VS TapTap

Here is a big list

also, you can find more material you apps here: https://github.com/nyas1/Material-You-app-list

Anyway, here's a list of apps that used Material Design 3, Material You and Both

List of Material You apps. There is a tag for FOSS apps.

Consider taking a look at this list of MY apps. Lots of great implementations in there, my personal favorite probably being TachiJ2K which I use daily.

I was also using that app, as it has a nice UI as i learned from this list(featured on best MU apps on that list) and it mentions it as Nonfoss app (maybe before it used to be foss app). So, with a sad heart i left that app as i prefer foss apps more although it has the best UI. We normal people can't find out what can be tracked...

Material You App List

Tap, Tap (version 1610): double tap on back of device

This app has double tap with sensitivity adjustment, works perfectly for me with no noticeable battery drain. https://github.com/KieronQuinn/TapTap

Just a quick shout-out of an app I discovered, it's a backport of quick tap for older android versions, but also has sensitivity adjustments and works great for me. Always triggers when I double tap (unlike the originl) and I've never had it accidentally trigger. https://github.com/KieronQuinn/TapTap

That said, some apps do use Material Design 3: Sync, Simple File Manager, Auxio Tap, Tap

Github

Tap Tap provides customizable tap routines

Tap, Tap (version 1600): double tap on back of device
