2019-10-30	A *****	I looked on the net to find the rpm of the trex 150 was 7500 according to align with 8200kv motor. This app read my rpm at 7700 and i have the 9000kv motor so it's well within the ballpark. Crazy enough for a cheap app

2019-08-30	A *****	Very accurate. This app treats your copter as a musical instrument and listens to the quadruple harmonics of your copter's noise, about the frequency of piano tuning fork A4=440hz, which is the frequency humans are most sensitive to and the phone's microphone most sensitive to. Then divide this frequency by 4 to get the blade frequency, and then divide it by the number of blades. This is basically a guitar tuning app repurposed.
