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.
