FPV Racers Chrono

This app is mainly useful to keep track of progress in FPV racing, expecially when you fly alone.

Usual problem is that you don't know how to trig a timer ad your fingers are busy on sticks so..
This app allows different trigger methods.
You can use the play/pause button of the earplugs, for example putting it between your teeths or DIY a simple cable using a foot pedal, or you can 'learn' the app to detect a fast movement to let it trig the lap repeating the movement later. For example you can fix your phone to a leg and learn a fast up/down movement so you can use this to trig

If someone is helping you, tapping on the screen or pressing the volume+ button does the same job.
App saves lap time sessions together with propeller type and battery time, to be analyzed later.

A useful feature is vocal synth of time so you can hear in earphones, with customizable messages for lap and best lap. if you set the track lenght you will also have the km/h mean speed.
