I have tested 1.3. It’s promissing app however some issues and propsals if I may.

-COG not working. Old version however it does!
-SOG would be OK with one decimal only.
-AWA – would prefer needle instead of boat. Plus, at the same gauge TWA would be appreciated since it can be easly calculated using SOG and COG.
-position scale to move after other gauges.
-Screen looses all the data everytime I minimase the app, reconnection required.
