Dive Calculator vs Dive Kit

A wide variety of scuba based calculations for all levels of divers. Basic Calculations Include: -ATA -SAC / RMV rates -Tank volume / Pressure rating -Basic unit conversions Nitrox Calculations Include: -EANx best mix -Integrated top-up and bleed down mix calculations -What if top–up -EANx mix planning Trimix Calculations Include: -Integrated top-up and bleed down mix calculations -What if top–up -Trimix planning -Best Trimix -Heliair All blending and top up pages include gas volume and cost calculations. Trimix gas fill orders can be changed by simply dragging the icons to select the fill order. Oxygen can be selected as narcotic / non-narcotic on the appropriate calculation pages. Results can be copied to the clipboard in a text format for use in E-mails, messages or other forms of documentation. All pages support metric and imperial units. Many pages include both metric and imperial units.

Dive Kit is a decompression planner for technical divers, and a set of dive tools for every diver. The Deco Planner covers open-circuit, nitrox, trimix and CCR dives on Bühlmann ZH-L16C with gradient factors. It is the only paid tool: a one-time lifetime purchase or a subscription. The other eleven tools are free, with no ads and no account. Large text for direct sun and large buttons for wet hands. Works offline. Deco Planner - Multi-level profiles, with stops between levels when the plan needs them and gas switches where the PPO₂ allows - Gradient factors, last stop, ascent rates, oxygen breaks, stop rounding (1 min, 30 s or 1 s) and PPO₂ limits per gas, all set per plan - Contingency tabs: deeper, longer, lost gas, or your own. Each shows the change in run time, TTS and CNS against the base plan - Modifiers: working and deco SRMV and a delay at depth, on the base plan or on one contingency - CCR: setpoint schedules by depth, diluent switches, dilout, and open-circuit bailout from the end of the profile, after any level, at a run time or on ascent - Gas per cylinder: remaining pressure at each stop, a reserve per cylinder, ascent pressure, and what happens when a cylinder runs dry - Warnings with the number and the limit: PPO₂, END, gas density, CNS, OTU, hypoxia, reserve - Repetitive dives, with tissue loading carried over the surface interval - Plan variants, overlaid on one graph - Share by QR code or link; anyone can open a shared plan without paying. Export the table or a slate as PDF, image or text, ready to print How the engine was checked Dive Kit's engine is an independent implementation of ZH-L16C, written from the published papers. It was cross-checked on 33 dive profiles. The method and the differences found are published at divekit.app/docs/engine/how-it-works/. Agreement shows the math matches. It does not show a plan is safe. Free Tools - Best Mix: nitrox and trimix by MOD, helium by END, with narcotic and density limits - Gas Specs: EAD, PPO₂, END and gas density, with warnings at your limits - Gas Usage: multi-level consumption, turn pressure, thirds to sixths - SAC/SRMV: your breathing rate from a real dive - Buoyancy: weighting from suit, body, gear and water, with lift and overweighting checks - Blend Planner: partial-pressure and continuous blending with real-gas corrections and expected analyzer readings - Mix Result: what a top-up or a decant gives you - Checklists: your own pre-dive routines and rebreather presets, with timers that keep running when you close the app - Cylinders, Converter, Dive Signals: 90+ illustrated, searchable signals and 35+ cylinder specifications Learning Tutorials on gas physics, decompression theory and trimix, and help on key results. Certification Wallet 25+ agencies and 190+ certifications. Add photos of your cards and show one full screen at the dive centre. Your profile holds your dive insurance details. Options - Offline, on phones and tablets - Eight languages: English, German, Turkish, Swedish, Russian, Polish, Simplified Chinese, Korean - Five styles, each in light and dark, and a choice of two app icons - Automatic backup to your own iCloud Drive or Google Drive, if you turn it on No account. Your data stays on your device unless you share a plan or turn on backup. Analytics and crash reports can be turned off in Settings. Warning and Disclaimer Dive Kit is a reference and planning aid for trained divers, and that covers all its tools. It is not a dive computer and not a substitute for training. The deco planner is for divers trained in decompression diving, and gas blending is for trained blenders. Results can be wrong, so check every result against a second source. Dive Kit is provided as is, and you use it at your own risk.
