Dive Plan vs Superior Dive Log & Planner

Dive Plan is a dive planning and logbook app for recreational scuba divers. Plan single and repetitive no-decompression dives, work out Nitrox mixes, keep a complete logbook, and check the weather and water temperature at your dive site — all from your iPhone or iPad. PLAN YOUR DIVES • Plan first dives and repetitive dive chains using standard recreational no-decompression tables — pressure groups, no-decompression limits, and surface intervals • Repetitive dives carry each dive's pressure group into the next, with the surface interval pre-filled from real elapsed time • Clear safety-stop guidance (required or recommended) for every dive • The planner won't produce a dive that exceeds no-decompression limits — it tells you instead • Metric or imperial, switchable anytime NITROX / ENRICHED AIR • Set your oxygen fraction (FO2) and partial pressure limit (PPO2) • See maximum operating depth (MOD) and equivalent air depth (EAD) for each dive DIVE LOGBOOK • Record depth, bottom time, date and time, location, tank pressures, air/surface/bottom temperature, gas mix, and notes • Automatic, continuous dive numbering • Review your history on the dashboard: total dives, total bottom time, deepest and longest dives, plus today's dives and your last ten AT-A-GLANCE DASHBOARD • No-Fly countdown based on the DAN Flying After Diving guidelines — 12 hours after a single dive, 18 hours after multiple dives or consecutive days • Readiness: whether your next dive plans as a fresh first dive or a repetitive one, with a live surface-interval timer since your last logged dive • Current weather and sea-surface temperature for your location WEATHER & WATER CONDITIONS • Local forecast — current conditions, highs and lows, wind, and precipitation, powered by Apple Weather • Map view with search and dropped pins to check conditions anywhere • Sea-surface temperature from NOAA satellite data CERTIFICATIONS & CHECKLISTS • Keep your certification cards, with front and back photos, on your device • Build pre-dive and gear checklists and run them before every dive PRIVATE BY DESIGN • Your dives, logs, and photos stay on your device and in your own iCloud • No third-party analytics, no advertising, no tracking DESIGNED FOR IPHONE & IPAD • Universal app, all orientations • Light, dark, and system appearance, with optional background themes DIVE PLAN BASIC & PRO Dive Plan is free to use: one dive plan per day, a 20-entry logbook, one certification card, one checklist, and full weather access — free, forever.

Always dive within the limits of your training and certification, verify every plan against your own dive tables and dive computer, and never rely on a single tool. Calculated results are estimates. You are responsible for your own safety in the water. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Superior 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 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/
