Frequently asked questions
Everything you need to know about DiveOne — from device compatibility to data privacy.
What devices does DiveOne support?
DiveOne 1.0.1 supports Apple Watch Series 10 and later and every Apple Watch Ultra model, including Ultra 3. Native recording is limited to 6 m in this release; Ultra hardware has a 40 m sensor range.
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?
Unlimited dive recording and logging, core safety features, 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?
Account creation is optional for on-device dive tracking. Planner, support, and beta-program flows are separate consented features.
Where is my dive data stored?
Dive recordings stay on your iPhone and Apple Watch by default. Account and web-planner cloud features store data on DiveOne servers only with explicit consent.
Can I export my dive data?
Yes. You can export your complete dive history in CSV format at any time from the app settings.
What dive modes are available?
DiveOne is developing three modes: Scuba (recreational dive tracking), Freedive (breath-hold tracking), and Snorkel (surface session tracking). All modes are currently in development.
Does DiveOne work with the regular Apple Watch?
DiveOne 1.0.1 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.
