Help build the honest dive log
DiveOne is a dive logbook and directory, built with the diving community. Divers, instructors and ocean lovers can help in three ways.
Three ways to help
Do as much or as little as you like. Every contribution makes the log and the directory better for everyone.
Fill & verify dive-site data
Add missing dive sites, correct depths and coordinates, and confirm the details you know first-hand. Accurate data is the backbone of the directory.
Send feedback from real dives
Use DiveOne 1.0.2 from the App Store on your dives and tell us what works and what breaks. Your feedback shapes what we fix next.
Create content
Share photos, video and writing from your dives. Good stories and images help other divers discover sites, with your name on them.
DiveOne 1.0.2 is on the App Store. It records depth to 6 m on a supported Apple Watch. It is not a dive computer and gives no decompression or safety-stop guidance.
