Frequently asked questions
Everything you need to know about DiveOne, from device compatibility to data privacy.
What devices does DiveOne support?
DiveOne 1.0.2 supports Apple Watch Series 10 and later and every Apple Watch Ultra model, including Ultra 3. DiveOne records depth to 6 m. The Apple Watch Ultra sensor range is 40 m; DiveOne records to 6 m on every supported watch.
Is DiveOne a dive computer?
No. DiveOne is a recreational dive tracking and logbook tool. It records available depth, time, and temperature data but does not calculate decompression, NDL, gas, ascent, or safety-stop guidance. Use a dive computer as your primary instrument.
How much does DiveOne cost?
Dive recording and logging and at least one open export format are free forever. DiveOne has no subscription or in-app purchase today.
Do I need to create an account?
No. An account is optional. You can record dives on your watch without one.
Where is my dive data stored?
Dive recordings stay on your iPhone and Apple Watch by default. If you sign in on version 1.0.1, the app may copy your logbook and attached photos to DiveOne servers; this is off from version 1.0.2. Dives you add or import on the website are stored in your DiveOne account and appear only there. Imported dives are labelled and read-only, and reconstructed estimates are excluded from website totals. The app does not sync with the website.
Can I export my dive data?
Yes. Export a CSV summary or create a JSON backup at any time from the app settings. UDDF export is in the app from version 1.0.2.
What dive modes are available?
DiveOne has three modes: Scuba, Freedive, and Snorkel. All three are in the app today, and each records depth to 6 m.
Does DiveOne work with the regular Apple Watch?
DiveOne 1.0.2 supports Apple Watch Series 10 and later and every Apple Watch Ultra model, including Ultra 3. Models without a depth sensor are not supported.
Is DiveOne safe to use while diving?
DiveOne is a tracking tool, not a safety device. Always use a certified dive computer, dive within your training limits, and follow all standard diving safety practices.
How do I install DiveOne?
Download the current release from the App Store. DiveOne is not offered in the European Union. The status page lists supported devices, current limits, and where the app is offered.
How do I close my DiveOne account?
Use Close account under Account on the website or Delete account in the iPhone app. Self-service closing stops access immediately and schedules deletion after the 30-day grace period. Or email privacy@diveoneclub.com from your account email. We close the account and delete its data within 30 days of your request.
Can I import a logbook on the website?
Yes. Import CSV in the DiveOne logbook column format, or a UDDF file, into the website logbook. Imported dives are labelled and read-only. Reconstructed estimates are excluded from dive count, bottom time and maximum depth. The app does not sync with the website logbook.
DiveOne is a recreational dive tracking and logbook tool. It is not a dive computer and does not replace professional diving equipment. Always dive within your training and certification limits.
