Orientation will not lock in landscape

[moto316]

Trying to get landscape locking to work. Holding my iphone4s in landscape orientation with laptimer open, swipe up and hit orientation lock button and the app immediately reverts to portrait mode even though I'm holding the phone in landscape. It stays locked in portrait mode fine however. iPhone4s and iOS 9.2

True, and probably a bug. Why do you want to lock it? LapTimer automatically locks itself once you start driving.

I bought this to be used on a motorbike. So does it need to complete a full lap to lock or does it lock once it detects movement?

It locks when detecting movement.
