RSC Nitrox

RSC Nitrox is a fast, focused enriched-air (Nitrox) dive-planning calculator for divers. Drag a slider and every number updates live over an animated underwater scene - no menus, no clutter, no sign-up.

FOUR 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 safety flag

BUILT FOR THE WATER
• Live results as you drag - or drag the diver up and down to set depth
• A nitrox tank that shows the O₂ / N₂ split at a glance
• Depth ruler, drifting light and rising bubbles - readable and calm
• Meters or feet, sea or fresh water
• Configurable max PPO₂ (1.2–1.6) and max O₂ ceiling (40 / 50 / 100%)

MADE TO TRUST
• Works fully offline
• No ads, no tracking, no accounts - your inputs never leave your device
• Free. Optional tips help development, but every calculator stays free for everyone
• Interface in English, German, French, Italian, Spanish, Ukrainian and Russian

A companion for planning enriched-air dives on the reef. Accuracy cannot be guaranteed - always confirm your mix with an analyzer before entering the water and dive within your training and limits.
