Hello,
I'm currently working on a mobile app that give you a look at the steem wallet.
This is a very simple app that currently only displays the wallet data.
You can also transfer over SteemConnect (in future direct from the app without SteemConnect).
The only information this app need is the username and nothing more.
The Wallet data is stored on the phone, so you can see anything even without internet connection.
Current features:
Wallet history view
Transfer via SteemConnect
Storage on the phone
basic functions
Future features:
Transfer without SteemConnect
Regular payments (like each month)
payment requests
View in Euro and USD
and more
It's my first Android app in Playstore:
