Diveplanner Tec & Rec vs mvPlan

Plan your technical or recreational dives in seconds on your iPhone, iPad and Mac ! Diveplanner is a full featured planner for technical and recreational scuba diving. It features various modules to quickly plan one or multiple dives including gas contingency and oxygen toxicity. Diveplanner was designed as a safe and reliable tool for divers. It helps plan technical and recreational dives quickly and easily and to share the schedule instantly with your dive buddy. Dive planning module: • Open Circuit / CCR, multi gas, decompression dive schedules up to 300 m/985 ft deep in fresh water or saltwater (including E​N13319) at sea level or altitude • Uses Bühlmann decompression model ZH16L-C with user selectable gradient factors as conservatism • Multi level dive instructions • Full automatic gas switch (from the list of selected gas for the dive) or manual gas switch or a mix of both • Full automatic contingency plans computation (lost decompression or travel gas) and ++ (too long/too deep) plans • Automatic bailout plan computation in CCR mode • Various information, caution or warnings for deep END, high or low PPO2, Setpoint, ICD, vestibular DCS due to ICD on gas switch • Computation of gas requirement and gas weight • Account for up to 6 consecutive dives with surface interval to account for residual saturation at start of the current dive • Works in Metric or Imperial units Dive table module: • Open Circuit / CCR, multi gas decompression dive table up to 66 m/210 ft deep and 60 min bottom time, in freshwater or saltwater (​including EN13319) at sea level or altitude • Uses Bühlmann decompression model ZH16L-C with user selectable gradient factors as conservatism • Account for up to 6 consecutive dives with surface interval to account for residual saturation while computing the dive table • Works in Metric or Imperial units • Translated in English, French and German

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.
