Diveplanner Tec & Rec vs mvPlan

Diveplanner Tec & Rec plans recreational and technical dives, on open circuit or closed circuit rebreather (CCR), in a few taps, and keeps your logbook. PLAN • Bühlmann ZH-L16C decompression model with your gradient factors, or the Thalmann algorithm of the U.S. Navy: VVal-79 for air and nitrox, XVal-He-9 for heliox CCR dives; compare a plan with both • Open circuit and CCR, down to 300 m / 985 ft, in salt, fresh or EN 13319 water, at sea level or at altitude • Multi-level dives, multi-gas decompression with automatic or chosen switch depths • Contingency plans computed for you: deeper, longer, lost deco gas, GF 100 and the CCR bailout • Warnings for ppO2, END, gas density, isobaric counter diffusion, CNS and OTU • The decompression chart of each plan: the profile, the tissues' ceilings at GF 100 and at your gradient factors, the leading tissue • A dive day of as many repetitive dives as you need, with their surface intervals • Saved plans in folders, shared as files GAS • Describe your cylinders: the plan gives the pressure at the end of the dive, the turn pressure, the rock bottom and the maximum bottom time your gas allows • Gas needed by volume and weight, per gas TABLES • Dive tables by depth and bottom time for your own gases, gradient factors and conditions, with the previous dives of the day • Share or print the table as a PDF TOOLS • Gas blender: partial pressure blending of nitrox, trimix and heliox from what is left in the cylinder, ideal or real gas; the best mix for a depth from your ppO2, END and gas density limits, and the cylinder label • Tides: the tide of a day anywhere at sea, from the nearest NOAA tide station or the EOT20 global tide model, its high and low waters, and the tidal currents and slack waters of a nearby current station, read to the minute on the chart • Photo colors: restore the true colors of your underwater photos and videos, their blue or green cast, haze and missing red corrected, with the depth of your logged dive; compare before and after, then save or share LOGBOOK • Log your dives by hand, from a plan, or download them over Bluetooth from a Shearwater dive computer (Petrel 2, Perdix, Perdix AI, Nerd 2, Teric, Peregrine), with the profile, stops, gases and sensor values • Photos, dive sites on a map, statistics, tags, search and filters • Synchronised between your iPhone, iPad and Mac with iCloud • Export to UDDF, Subsurface, CSV, a PDF logbook and .divelog archives; import UDDF and Subsurface SHARE • Ready-to-cut dive schedules as a PDF, for your buddy or your slate: every plan, the gas and cylinders, CNS, OTU and warnings EVERYWHERE • iPhone, iPad and Mac • Metric or imperial units • In 12 languages, each with its user guide LICENCES • Rec, free: one gas, air or nitrox up to 40 %, down to 66 m / 210 ft • Tec Basic: up to 3 gases, nitrox up to 100 %, normoxic trimix and triox • Tec Advanced: unlimited gases and depth, hypoxic trimix • Try every feature free for 2 weeks Diveplanner is a planning aid. It does not replace training, experience, a dive computer or your own judgement: always dive within the limits of your certification.

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.
