Cover automatically recognizes when you’re at home, work, or in the car and learns which apps you use most in each context. So when you’re in the car, maps are right there. At work, your calendar and documents are at your fingertips. You can set a custom ringer volume and wallpaper for each location.
Cover is built exclusively for Android - it couldn’t have been built on any other mobile platform. Android’s openness allows Cover to rethink how a phone should behave and improve core features.
