What apps would you love to have open-source alternatives for? - Lemmy.World

It seems like the FOSS community is continuing to grow, and FOSS apps keep getting better (Immich reallh blew my mind recently), which is a big win 😎 but there are still many apps I use that I would kill for an open source alternative. I am curious what you guys think? Are there any apps you’d love alternatives for?

Plain banking apps for smartphones. Having those developed in the open would hopefully make it possible to have forks that work on rooted devices without hiding magisk and whatnot.
i learned about GNU Taler the other day from one of the OS communities
GNU Taler - Taxable Anonymous Libre Electronic Reserves

A payment system that makes privacy-friendly online transactions fast and easy.

Sure, I guess. Not what I was after but it has potential in its own right.
