About the App
Nitrox Helper is a professional Enriched Air Nitrox (EAN) calculator for SCUBA divers. It provides four essential calculations that qualified Nitrox divers use when planning dives with oxygen-enriched breathing gases: Best EAN Mix, Maximum Operating Depth (MOD), Equivalent Air Depth (EAD), and Oxygen Partial Pressure (PPO).
The app supports both salt water and fresh water calculations, recognising that different water densities produce different pressures at the same depth. This makes it suitable for ocean divers, lake divers, and quarry divers alike.
With 8 languages, 16 colour themes, metric and imperial units, and configurable decimal precision, Nitrox Helper is designed to be accessible and personal for divers worldwide.
