## What is mvPlan?

Plan your dives with confidence. mvPlan is a full-featured decompression planner for recreational and technical divers, built on the proven Buhlmann ZHL-16B and ZHL-16C algorithms with gradient factor conservatism.

OPEN CIRCUIT & CLOSED CIRCUIT
Plan dives on standard open circuit or CCR rebreathers with fixed or dynamic setpoints, multiple diluents, and full bailout planning with stress gas consumption.

ALL GAS MIXES
Air, Nitrox, Trimix, Heliox, pure O2 -- use any combination with automatic MOD, END, EAD, gas density and ppO2 calculations.

MULTI-LEVEL PROFILES
Build complex dive profiles with multiple depth changes, gas switches, and diluent changes. mvPlan computes the optimal decompression schedule for the entire profile.

SAFETY MONITORING
Track CNS and OTU oxygen toxicity, narcosis exposure (END), gas density alerts, and isobaric counter-diffusion (ICD) risk. Configurable alerts keep you informed.

GAS PLANNING
Calculate required gas volumes for each mix with configurable RMV rates for bottom, deco, and stress phases. Tank capacity checks ensure you carry enough gas.

BAILOUT PLANNING
Full worst-case bailout calculations for CCR divers: configurable bailout delay, stress RMV, and independent bailout gas selection with complete decompression schedule.

VISUAL DIVE PROFILE
Interactive depth/time graph with ceiling overlay, gas change markers, and pinch-to-zoom. Tap any segment to inspect tissue saturation across all 16 compartments.

PDF EXPORT & SHARING
Generate print-ready dive tables with all parameters, deco schedule, and gas requirements. Share plans directly from your device.

SAVE & ORGANIZE
Save unlimited dive plans, import/export as JSON, rename and manage your plan library.

FULLY CONFIGURABLE
Gradient factors (with presets), ascent/descent rates, last stop depth, altitude compensation up to 4000m, salt/fresh water, metric or imperial units.

6 LANGUAGES
English, French, German, Spanish, Italian, Polish.

Dark and light themes for comfortable display in any conditions.
