I have been trying this app both on PC and on Android, and man they are great!
As for Android, I have a suggestion - could you make the notification bar a little bit more customizable, or at least show some extra information.
For example, currently when you switch the notification bar to show only your daily usage, you can’t see the data remaining for the plan. It could be quite useful
If possible also, it would also be nice to make it cleaner! (not only show it in plain text).
