I previously tried a similar app by Obut, it did not work at all. This app actually does work! Im using it on a pixel 7 pro. Make sure to position the camera straight above the jack and use the accelerometer/gyroscope setting, it totally works. Anytime I forget my tape measure when playing petanque, I will make use of this app in the future. Really really usefull.
