Initially looks quite good on the ground... But take to the air after having put my HTC Desire into 'Airplane mode' - to comply with flight regulations your application which once worked perfectly on the ground now tells you it is 'unlicensed for this device' and promptly closes when you hit 'ok'... So if you have any intention of using this in the air - for fun purposes - think again it does not work thanks to this rather major licensing restriction! Update May 2017 - it is slightly better, you can now launch it 3 or 4 times but as the licensing has no internet connection (usual if flying!) - it will then switch to unlicensed and you cannot run it anymore - until you have landed and have internet again.. It has been this way for many years now so I guess the author is in no hurry to fix this rather fundamental issue!
Not working on new equipment. This app has worked well on my Samsung Note 4, but crashes on opening on my new Google Pixel C running Android 6.0.1. It seems the new Android is giving it problems.
Nexus 7 Its affected by airplane vibration
Nexus 7 I have tried a few of these and most are useless but I flew today with this app using a Nexus 7( in VFC conditions) and it appears to work very well. Both Pitch and Roll are responsive . Accurately represented my pitch and roll and orientation for over 30 mins of testing. Bert Barrott
GPS Info very good, heading,alt, AS. Pitch - about 4 , Roll - 3 at best (all over the place) Like the airport frequency at the bottom of page
Nexus 7 An excellent and well thought out app. It tracks in lock step with my attitude indicator. Would highly recommend it.
Further improved Kalman filter, fusing gyro, accelerometer, GPS and magnetometer information for better stability.
