Reserve Gas app for iPhone and iPad

This is a "easy to use" tool to calculate the amount of reserve gas / bail out gas you need to make a dive.
just fill ind the parameter and you will get the,
* accent time from bottom to the first gas switch,
* the amount of gas needed to get you and your team safe to the first gas switch, in case of an "out of gas" both in litter and in bar
* and finely how lang dive time you have on the bottom, if you are not using your reserve gas

The program can be used both fore Tec and Rec divers.

The algorithm for the calculation is bases on the classic DIR method to calculate the reserve gas.
