The turn and bank indicator was exchanged for GPS ground speed.
The wind speed reading source was changed from cellular data to GPS data to allow the app to work at all altitudes.

The pitch can now be adjusted to match the mounted angle on the dash.
Here’s how:
Mount the device.
Tap the pitch indicator quickly three times. A message pops up.
Tap the message 1 time fast, then tap and hold the pitch indicator for three seconds until the pitch shows zero.

Changed the compass from magnetic to GPS sourced data. This provides greater directional accuracy, irrelevant of device position, but it only works when the device is in a steady motion.

The accuracy of the pitch indicator has been improved so the analog and digital readings match.
The direction of the ball in the turn co-ordinator has been adjusted to react more to centrifugal force for greater accuracy.
