Do not purchase!
Paid a while back and the app worked fine. After I upgraded to iPhone 6s+ I reinstalled the app on my new phone. Tried restoring purchase and it never restored. Ive emailed their support twice now and never got a response. Dont waste your money, there are other apps out there.
Other observations, the motion gestures dont work well and the weather fails to update regularly. Also, the display doesnt reliably turn as you rotate the phone and will sometimes turn bit not recenter and looks off.
You can find better products for free on the App Store, just take a few more minutes and scroll down.
