If you want a proper journaling app :

Inner Ink

Linked

Rednotebook seems solid

Having markdown means you can use it in a variety of apps but I’m not sure how many have encryption (obsidian and joplin maybe?)

You could also try Trilium Next

I also found Darkwrite. Can export as HTML

I recently found this on github : Muzik-offline

I’m also keepin an eye on this as it has flac support : Wora

There are more on this list : Alternativeto

foobar and musicbee are not open source afaik

Is this AI generated ?

Paisa was open source. The developer then removed it I guess. The repo you linked doesn’t host the app. The developer said it’s used for reporting issues. Edit : The repo is private

Cashew is open source GPL licensed. But it uses Google libraries which I guess prevents it from being on f-droid. Last time I used Cashew, the premium features notifications could be ignored and the app could be used completely for free, I’m unsure if that was changed though.

I found another app but it’s not on f-droid, you’ll have to use Obtainium - Monekin
