With this app, it is possible to make Caches in which a Chirp was used.
Either you use the built-in chip of your smartphone or you use a USB ANT+ adapter via an OTG cable.
The name of the Chirp is displayed and since each cache uses a different coordinate notation, I show you the three most common. As well as of course the hint to is needed most.
By clicking on the various values, you can copy them to the clipboard to store on another place.
Now you can also write on chirps with this app, as long as you are the owner and know the pin ;)
The app is developed in learning programming, should not all work quite, I'm trying to fix that. So just write and I do my best.
