Phone sensors required - do we need others besides compass now?

[Lesley Binks]

Hi

I'm confused about the sensors required for this app to work.

The app's page in the Play store says we absolutely need a compass but doesn't mention gyro or accelerometer.  

There have been commits in March this year that indicate some 'fun' with gyro sensors - are these important to the useful functioning of the app?

Would love to know what the best set of sensors are to have to get this app running well.

Kind regards
