Tests in flight
The disclaimer rightfully says it is NOT intended to be relied on as a PRIMARY flight instrument, and as its reliability DEPENDS SOLELY the internal gyros of your iPad or iPhone, I wouldn’t say it was a bulletproof backup AHRS. Plus, I did NOT TRY to make it tumble, by performing a very steep turn.
But, if you lost your vacuum in IMC, and needed to get your wings level in a hurry to start a gentle decent from the soup, imho, you would be pretty happy to hav this little app onboard.
It performed as advertised. I’ve been told that iPhone internal gyros do tumble in extreme attitudes, so let the buyer beware.
Personally, I really like this little app, for what it MAY do to save your bacon, when you are out of other options. Just my opinion.

Thanks a lot for this fair review!
