Great little App!

This is a great tool to easy calculate your MOD or find the best mix for a specific dive depth. As a Florida-based weekly Nitrox diver I use this app all the time. My local dive shop has been having trouble with their bank fills lately, so I’ve been using Nitrox Buddy to double check my MOD. If you dive Nitrox, then you need this easy to use app!

Must have

This app is straight forward and quickly allows me to determine my depth levels. Other day first tank was 31% and second was 40% — this quickly let me feel comfortable knowing my limits.
