Thanks, I am on iOS so this is helpful. All I really care about is notifications, step tracking, and music control. It would also be nice to look at my calendar and check the weather, but those are not critical.
Devs are currently working on notifications, and you can help too if you are so inclined, but they aren't there yet. I am still on the BLE / GATT / ANCS learning curve, so I have not been much help.
