Skydiving audible altimeter and log book. Using pressure sensor built into your phone Altidroid works just like your regular audible playing sound alarms during freefall and recording a log of your jumps. Simply activate the application while on the ground, connect your headphones and jump.

Features include:
+ Background operation: turn it on and forget about it for the rest of the day.
+ Flexible alarm settings:
- configure any number of freefall or canopy altitude alarms,
- use any sound file for the alarm, choose one of the built-in sounds or make the app read a message.
+ Supports both imperial (mile/foot) and SI (meters) units.
+ Powerful logbook.
+ Automatic music silence: if you listen to music on the way up Altidroid will silence it as as soon as you exit the plane.
