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/
