Dear certified NitroxDiver

"Never rely on rules of thumb for diving" they say.

Well, we trust the rule of your thumb when it comes to calculating enriched air for diving with our NitroxCalc.
Squeeze out just that one last meter on your MOD? We tend to say: why not?

Optimizing your BestMix with pen and paper must be pretty dull. Why not finetune in real-time?

Can you swipe your thumb across the screen? Well, congratulations, you already know how to calculate then. Leave your manuals at home, they´d get wet anyways.

It´s never been easier. It´s never been fun before.

- calculate MOD*
- calculate BestMix*
- calculate Blending**
- Supports Imperial and Metric units (depends on your iPhone settings)
- No deco calculation based on DECO2000 table

* Maximum depth is 180 ft. / 60 m, Max O2 90%
** Pressure between 0 and 4000 psi / 0 and 300 bar

Please, write reviews for our app. And contact us directly with feature requests. We´re still going to improve NitroxCalc.
