About NitroxCalc

The NitroxCalc app is a straightforward tool for Nitrox/Enriched Air divers who want to plan their next underwater trip. They say you should never make rough estimates when diving – so be on the safe side with NitroxCalc!

Doing your calculations by hand are a thing of the past! Our app is ideal for divers who want straightforward operation and fast calculations. With the control via a simple slider, calculations according to the MOD, Best Mix and Blend models can be performed in real time. At any time, you can switch between imperial and metric units.

The NitroxCalc app offers you:
- iPad and iPhone version
- MOD calculation (maximum dive depth)
- Best Mix calculation (maximum oxygen percentage at a given target depth)
- Blending calculation
- Imperial and metric units
- CNS display for selected ppO2
- No-decompression time calculation based on DECO2000 table

Maximum depth is 60m (180ft) and maximum O2 percentage is 90%. The filling pressure has a fullness of 0 to 300 bar (0 to 4000 psi).

NitroxCalc does not replace a in-depth dive planning and should be used only after an authorized Nitrox course!

Feel free to contact us with suggestions for improvement and errors via the support address. We have an open ear for our customers and want to develop NitroxCalc further.
