2 because it used to be good
with the latest hardware and software updates the motion doesnt work on my devices any more. probably more apples fault with changing hardware and coding all the time.
The solution they will give you for the app is that you can turn off the motion part. Which seems like buying a car and only sitting in the drive way with it.... But hey who am I.
so in the short it may not work with you ios with motion control. But hey it just might.
