## What is RSC Nitrox?

RSC Nitrox is a fast, focused enriched-air (Nitrox) dive planner for iPhone and Apple Watch. Dial in your mix and depth and get the four numbers that matter - instantly, offline, in a clean underwater interface.

CALCULATORS
• MOD - Maximum Operating Depth for any EANx mix
• Best Mix - the richest usable mix for a target depth
• EAD - Equivalent Air Depth for a mix at depth
• PPO₂ - partial pressure of oxygen, with a clear safe / caution flag

BUILT FOR DIVERS
• Fully offline - no account, no ads, no tracking
• Metric or imperial, salt or fresh water
• Adjustable max PPO₂ (1.2–1.6) and max O₂ content
• Live results as you drag - or spin the Apple Watch Digital Crown
• Seven languages: English, Deutsch, Français, Italiano, Español, Українська, Русский

APPLE WATCH
Plan on the reef without your phone - the independent watch app carries every calculator on your wrist.

Accuracy cannot be guaranteed. Always confirm your mix with an analyzer before entering the water and dive within your training and limits.
