Import

All your dive data, in one place

Works with major dive computers. Differences in data and processing between makers and models are absorbed as much as possible — so every dive gets the same analysis.

* Dives can’t be imported straight from the dive computer — export the data from each maker’s app or website first. * Questions about importing or data handling? Feel free to get in touch. Sharing sample data also helps us improve the app.
