Essentially it took me around 1.5 minutes to figure out how to login on the app. You tap buttons and it says login required. Why not just open up the login interface? Or provide an easy link or ask immediately after first run.

Or on the sidebar, have an obvious banner that says “Login”.

Just too many taps to get logged in to add your first account, and too difficult to figure out where to do so. And no help when the app prompts you to login. Make it super easy to do that!

Edit: I have developed modern UX/UI, so if even I found it confusing, I know non-expert or unfamiliar users are going to fail to ever use this app, which would be a shame. It’s really great!
