We incorporate the newest features from the used APIs. It is time to make use of the powerful hardware that we walk around with eveyday.
As few permissions as possible. What the user does is his own business. We make it our mission not to log any of the users activities or personal data.
We aim for a clean design. No more ugly grey UIs. If it is pleasing to the eye, it can serve its purpose.
Gestures must feel natural and intuitive. If a user can't figure it out in less than 1 minute, then it is not well designed.
