## Description

Nitrox Calculator does the published gas-mixture arithmetic for enriched-air (nitrox) diving - MOD, EAD, best mix, and cylinder blending, shown with the formula on screen.<br><br>This is a gas-mixture calculator, not a decompression planner or dive computer. It implements no tissue/compartment model, no no-decompression-limit table, and no dive-plan or ascent schedule - it answers what a gas mix does at a depth, never how long you can stay down or how to ascend. Enriched-air diving requires specific training and certification; this tool does not replace training, a dive computer, or analyzing your own cylinder.<br><br>MOD<br>- Enter an oxygen percentage (or pick a common mix like air or EAN32) and a ppO2 limit<br>- See Maximum Operating Depth for that mix and limit<br>- See the actual ppO2 at your planned depth, flagged if it exceeds your limit<br>- See Equivalent Air Depth (EAD) for logging against an air table or air-calibrated computer<br>- See Equivalent Narcotic Depth (END) - oxygen counted as narcotic or nitrogen-only, both conventions used by different training agencies<br>- Switch between metric and imperial depth, and salt or fresh water<br><br>BEST MIX<br>- Enter a planned depth and ppO2 limit<br>- Get the richest whole-percent nitrox mix that keeps ppO2 at or below your limit, always rounded down for safety, with the actual ppO2 it produces<br>- Blend a cylinder: enter starting pressure and mix, target pressure and mix, and a top-up gas<br>- See how much pure oxygen to add first, then how much top-up gas, using the partial-pressure blending method - or a plain explanation when the target cannot be reached by adding gas alone<br><br>DIVES<br>- Save named dive presets (oxygen percentage, depth, ppO2 limit) and reload them into MOD<br>- Keep a history of calculated results and favourite the ones you want to keep<br><br>BUILT FOR THE BOAT OR THE DIVE SHOP<br>- Fast entry with minimal taps<br>- Works offline<br>- No account required<br>- Saved dives and history stay on your device<br><br>This app is ad-supported. The calculators are available to use; watching a short ad unlocks saving results, calculation history, and saved dive presets.<br><br>If you need a straightforward MOD calculator, EAD calculator, best mix calculator, or nitrox blending calculator for enriched-air diving, this app gives you the numbers with the formula shown - always alongside the training and certification you already need to use nitrox safely.
