DiveOne

Shallow dive log & depth data

Free

Log dives on the Apple Watch you already own. Automatic shallow depth logging, import your deeper dives, and export your whole logbook anytime. DiveOne turns the Apple Watch you already own into an honest dive logbook. WHAT IT IS DiveOne records your dives and keeps a clean, exportable logbook. On Apple Watch it logs shallow depth automatically; your deeper dives come in from Apple Health, UDDF, or Subsurface. Every dive reads like an instrument — depth, time, temperature — not a lifestyle feed. ON-WRIST DEPTH LOGGING Start a session on Apple Watch and DiveOne logs your shallow-water depth and time hands-free. It is a depth logger — a calm, honest instrument for the water you actually reach on the wrist. BRING IN YOUR REAL DIVES Import deeper dives from Apple Health, or from any UDDF / Subsurface export. Your history lives in one place, in your own hands. OWN YOUR LOGBOOK Export everything to UDDF or CSV whenever you want. No lock-in. Your dives are yours to keep, move, and back up. READ YOUR DIVE LIKE AN INSTRUMENT A single, legible depth gauge and a clear profile. Max depth, duration, temperature, and site — the numbers that matter, nothing that doesn't. DIVE SITES & OPERATORS Browse dive sites and the centres and boats that run them, so you know where you're diving and who's behind it. WHAT DiveOne IS NOT DiveOne is a dive logger and logbook. It is not a dive computer: it does not provide decompression, no-decompression limits, ascent-rate, or safety-stop guidance. Always dive with, and follow, your own independently certified dive computer and your training. Free to use. Works with Apple Health: completed Apple Watch dives are saved as underwater workouts, and dives can be imported from Apple Health.
