Three stars for potential
The possibilities of this are amazing!! Bought the pro app to support you guys. But you need to iterate fast or this will become a nice try pretty quick.
You must make the app update mail faster. Each time I demo this to people, the "cool" factor wears off quick because email wont update quickly.
When Im notified for mail you havent even downloaded yet? Not good, Daniel-san. Not good.
Finally, you need to manage notifications. I added ideas to your help pages that you need to copy either VIP/thread notifications for messages from Apple mail or use gmails inbox management features so Im not being notified of EVERY message.
