Awesome Thank You!

The app is great easy to use, all values are correct, great functionality. It would be awesome if mod 1.5 was available.

KISS principle at its best

"Simple stupid" apps which does exactly what it should. No bothering ads, no weird user interface, fast and easy Nitrox calculation every time. Most simple app but best compared to other diving apps available in store.

Nitrox buddy is my buddy!

Love this little app. I use a variety of concentrations so it makes it easy to plan dives.
