TurTur Dive Log vs Puffin

TurTur is a personal dive logbook and planning companion built for recreational scuba divers who want a clean, fast, and capable tool on their iPhone. LOG EVERY DIVE Keep a detailed record of every dive — site name, location, date, depth, duration, water temperature, and personal notes. Add a dive manually in seconds, sync wirelessly from your TurTur-compatible dive computer over Bluetooth, or import dive files from Garmin, Shearwater, or Suunto. DEPTH PROFILE CHARTS Visualise your dive with a full depth profile chart pulled directly from your dive computer's sensor data. See your maximum depth point, safety stop position, and mid-ascent rate highlighted in the chart. Toggle between the depth profile and water temperature graph for a complete picture of each dive. DIVE EVENTS & SAFETY ANALYSIS For every synced dive, TurTur automatically identifies key moments: maximum depth, safety stop, and ascent rate. Ascent rate is colour-coded green, amber, or red so you can instantly see how the dive compares to recommended limits. MARINE LIFE LOGBOOK Log the marine species you spotted on each dive and build a personal life list over time. Browse your sightings by rarity, track what you've seen, and explore the species you're yet to encounter. MULTI-DIVE PLANNER Plan repetitive dives with the built-in planner. Set your target depth and bottom time for each dive, track your surface interval, and see your projected no-decompression limit (NDL) update in real time. The planner uses the Bühlmann ZHL-16A decompression model — the same scientific framework used in professional dive computers — for informational guidance. Note: The planner is a reference tool for recreational divers. It is not a substitute for a certified dive computer, professional dive training, or on-site judgment. Always dive with a certified dive computer. SHARE YOUR DIVES Create beautiful dive summary cards and share them directly to Instagram Stories, save to your Photos library, or share via any iOS app. Choose from multiple colour themes and card layouts — depth profile, gauge, or stats-only. WIRELESS SYNC & IMPORT Connect to a TurTur-compatible dive computer via Bluetooth and transfer your full dive history automatically. No cables, no desktop software. Already diving with a Garmin, Shearwater, or Suunto? Import your dive files directly — Garmin .FIT and Shearwater/Suunto .UDDF formats are supported. UNITS & CUSTOMISATION Switch between metric (m / °C) and imperial (ft / °F) units at any time. Your preference is saved and applied throughout the app. PRIVACY FIRST TurTur stores all your dive data locally on your device. Nothing is sent to external servers. No account required. No analytics. This is just the beginning. More features to support the dive community and island goers are on the way.
