Dashboard Air - Speedometer

Very excellent app for aeroplane fans. But it seems that cannot correctly sense the roll, (maybe the sensor cannot soley detect). Is there any other way (e.g. with the help of horizontal acceleration sensors) to calculate the real roll？ In addition, i think it's better do add the acceleration indicator of speed and attitude.

I believe, Android seriously needs long battery portable or inbuilt screen projectors for phones, in near future. Just like Daydream Headsets, they are less costlier than others but does there job brilliantly....

I use an older version(15.20) , works perfect, But it would be even better with a built-in movement map and log. App is Tested and runs on Xiaomi Redmi3s, Xiaomi POCO M3 and Samsung tablet A7/2022.
