Does anyone have personal experience with a key tracker like #Tile, #AirTag etc, which:

- has a FOSS client for Android (bonus marks if there is a Linux one too)

- doesn’t require registration / creating an account / signing up

?

(Obviously not expecting it to have network connectivity through other people’s phones)

Thank you!
