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.

Best Nitrox App Ever

I use this app all the time while doing dive planning and essentially makes my math simple to do, especially when checking out my Nitrox tanks and filling out my tank labels.

Thanks again Nitrox Buddy!

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.
