## Description

Dive Planner is a comprehensive tool designed for recreational scuba divers to safely plan their dives using PADI or SSI air dive tables. It supports both metric and imperial units, allowing precise input of dive depth, underwater time, surface intervals, altitude, and breathing gas mixes including Nitrox. The app calculates essential dive parameters such as end pressure groups, partial pressures (ppO2, ppN2), CNS, OTU, minimum surface intervals, and NDL using the Buehlmann ZH-L16B algorithm.

Additional features include gas mix calculators for Nitrox and Trimix, maximum operating depth (MOD), theoretical ocean depth (TOD) for altitude diving, equivalent air and narcotic depths, and a gas blender calculator for blending dive gases. Users can save and share dive plans, and pro users enjoy ad-free experience, backup via Google Drive, surface air consumption calculators, equipment checklists, and theme customization. Dive Planner is an essential tool for safe recreational diving, with a focus on no decompression dives only.
