A Twisting Phone

My son pointed me to this iPhone App, that twists a phone on its long axis, to enable automated panorama images. It was featured recently on Shark Tank.   An example where devices in a phone can be used via their unintended consequences.   I do note that there are many 'it doesn't work', comments in the  Reviews, and its stability on an on end phone are suspect.  And, what if Apple slightly changes the physical specs of the phone operation and the effect goes away?  Also there are competitive solutions.   So what are its realistic applications, beyond a 360 degree selfie?
