I need an app (for Android) that can follow the latest followers from the Twitter users that I define/select.
1. I open the App
2. I fill in the username of the Twitter user(s) (can be multiple)
3. The app follows the latest followers (that are not followed by me yet) from the Twitter user(s) that is defined in step 2.
I think there should be a possibility to log into my own Twitter account.
