Hmm, I checked that one out and it is indeed pretty nice but I don't think I can log in to my account with it. Just lets me view the public interfaces.

I login on the iOS app every day. There's a login option in the settings menu near the bottom.

Ah, I was using the webapp which doesn't have that functionality. Hmm, it appears the Android app is no longer in the play store. There's a dead link and a GH issue with no comments for two years.

I'll try to build the APK myself when I get some spare time.
