This app enables access to the AON2 Brilliant Pebbles audible skydiving altimeter. It can set up to 20 alarm altitudes, choose alarm tones as well as change units between feet and metres. A USB-OTG cable is required to connect the Brilliant Pebble to the Android device.

NOTE: For people on Samsung phones with Android 5.1.1 - there is a permissions issue which prevents the app from getting permissions to use USB! Unless Samsung fix this issue, or you upgrade your Android version unfortunately this app is will not work (despite Play Store saying it's compatible). Our apologies but this is outside our control, the AON2 team.
