A budget app. I’m tired of all the good ones being web apps that spy on you. Multiple accounts, recurring expenses, ability to set goals, there’s a lot of features you can implement (or not) depending on how far you take it.
Currently I use https://play.google.com/store/apps/details?id=com.onetwoapps.mh which gets the job done but I want similar functionality outside of android.
Fedora Kinoite exists already. It’s my daily driver for dev and gaming and works great for me.
