Does it work better on iOS? Because for me the app is very slow and sometimes just never loads anything

Yes. The Android app has some serious problems right now. Pixelix is probably the best Android app for now - though it has it’s own rough edges. It’s $2.99 in the Play store but free on F-Droid.

Using them together, however, does make for one complete (but inconvenient) app.

Alright I’ll check it out. Next I just need SDF’s instance to work because I love SDF and want to use them but the validation email won’t send
