Go to Settings->Face Gesture Settings and make sure "Use ARKit for Gesture Detection" is turned on. That will use the most battery life due to the processing required, but it will also be the most accurate. I'm guessing that forScore is using ARKit in the same way to do the facial gesture detection, so you should get the exact same result in MobileSheets. Page turns for me are instant when using that on my iPad Pro, so I'm not sure why you are saying the page turns are slow.

I suppose you could also try turning the "Use ARKit for Gesture Detection" off to use the other approach which requires less processing power to see if that works better on your device.
