Dive Toolbox vs Super Dive Log & Planner

DiveToolbox — Professional dive planning and gas calculation tools for recreational and technical divers. DECOMPRESSION DIVE PLANNER Plan single-level and multi-level dives using the Bühlmann ZH-L16C algorithm with configurable gradient factors. Get detailed ascent profiles, gas switch schedules, and comprehensive safety analysis including CNS, OTU, gas density, and END monitoring. GAS BLENDING CALCULATOR Step-by-step fill instructions for Nitrox and Trimix blending. Supports partial pressure and continuous flow methods with real-time MOD calculations. MOD / EAD / END CALCULATOR Instantly calculate Maximum Operating Depth, Equivalent Air Depth, and Equivalent Narcotic Depth for any gas mix. GRADIENT FACTORS EXPLORER Visualize how GF Low and GF High affect no-decompression limits and decompression schedules. SAC RATE CALCULATOR Calculate your Surface Air Consumption rate from dive data to improve gas planning accuracy. ROCK BOTTOM CALCULATOR Determine minimum gas reserves for safe ascent, including emergency scenarios with configurable safety margins. SUCCESSIVE DIVE PLANNER Plan repetitive dives accounting for residual nitrogen and helium tissue loading from previous dives. UNIT CONVERSIONS Convert between metric and imperial units for depth, pressure, volume, and temperature. KEY FEATURES • Multi-gas support with automatic deco gas switching • Save and organize dive plans in folders • Save tank presets for quick planning • Share plans via link or QR code • Export plans as PDF • Customizable diver profile (GF, SAC, PPO2, speeds) • Dark and light themes • Available in 7 languages: English, French, German, Spanish, Italian, Polish, Russian Terms of Use: https://divetoolbox.com/en/terms Privacy Policy: https://divetoolbox.com/en/privacy

Super Dive Log & Planner combines all of the features of a first-class dive log with an integrated world-class dive planner that learns from the dives you log. It is simple enough for recreational divers on their first open water dives, but grows with you through technical and DIR diving. THE LOG • Integrates with all popular dive computers to display your complete profile • Record dive sites with GPS, or lookup from the built-in database of thousands of sites • Marine life sightings with lookups from iNaturalist, OBIS and WoRMS, and a live list of what lives near any site • Track what you wore, the gear you used, and how it all made you feel • Draw in your narrative — a site map, the route around a wreck — with Apple Pencil, a finger, or the mouse. • Conditions fetched for every logged dive: the tide, weather, water column and currents that were actually running • Embed your photos • Gear tracking with service reminders; statistics across your whole history • The log correctly handles diving with drysuits, sidemount, CCR/SCR, trimix, stages, etc. THE PLANNER • Helps you balance your rig by estimating how much lead you’ll need based on your gear and dive history • What to wear, learned from what actually kept you warm at that temperature • Bühlmann ZH-L16 A/B/C decompression planning with gradient factors, tested to match Decoplanner • Recreational no-deco limits, Technical mode, and a DIR mode implementing GUE procedures — standard gases, minimum gas, staged ascent rates, oxygen breaks — tested to match Decoplanner • Helps you plan your dive with information about the current, expected visibility, expected wildlife, tides, and weather • Nitrox, trimix, SCR and CCR with setpoints • Lost-gas contingencies and deeper/longer what-ifs, priced into gas requirements • Altitude, water type and salinity handled throughout SITES AND DIVE SHOPS • A directory of thousands of dive sites worldwide, plus your own • Surroundings: charted depth, protected areas, wrecks with their history, today's reef reading • The site on a nautical chart (NOAA, EMODnet, GEBCO). • Dive shops, fill stations and clubs near you or near a site, with hours and directions YOUR COMPUTER, YOUR OLD LOGBOOK • Bluetooth downloads from all major dive computer brands • Imports from Subsurface, MacDive, Diving Log 6.0, Shearwater Cloud, divelogs.de, Ratio, DAN DL7, UDDF, Garmin FIT, Suunto, CSV, and Apple Watch Ultra dives from Apple Health • Two-way with divelogs.de: import your dives, and send new ones back to your account • Export your dives to DAN in DL7 format, the file DAN's dive-data tools read • Manage up to six logbooks at a time AI INTEGRATION • On Mac, a built-in MCP server opens your log to Claude, ChatGPT or any MCP client • Use AI to maintain your logbook, fix import errors, and plan your dives EVERYWHERE YOU DIVE • iPhone, iPad and Mac with iCloud sync • Twenty-eight languages • Local-first storage; your logbook stays yours • No account required Logging is unlimited and free. Premium planning features are free for your first week. Dive planning software is a tool, not training. Always plan and dive within the limits of your certification, verify schedules against your training and tables, and carry a dive computer. No algorithm can guarantee you will not get decompression sickness. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
