Current status
I currently disable any login feature since security is the most major concern in any "non-official" app. Taken Hive account@ned's advice, I'm currently debugging the local transactions signing and will re-enable these features after security tests and the code review are done by third-parties.
Distribution of the app
I have applied for Google Play Store, but because the app is still in early beta, it will be distributed through Early access and beta testing program from Google.
Please leave me your email here in the comments if you want to test the app. I will add you in the beta list and you could get the app from Google Play Beta Channel.
