Features
Read full description

Dive Converter allows users to retrieve their Oceanic+ and SSI/mares dives and export selected dives in Universal Dive Data Format (UDDF). The app works on iOS (iPhone and iPad) and on macOS. We have taken special care of making sure that all information of your dive that is also supported by UDDF is translated correctly. The generated UDDF files have been tested with multiple dive log programs on iOS and macOS. Features: - support for downloading dives, referenced equipment, user profile, buddy information from Oceanic+ - reverse geocoding of longitude/latitude to also get an address (at least country and region) where your dive took place - calculation of surface time (not contained in Oceanic+ data) - export all information according to latest UDDF standard - backup and restore of all dives in JSON and UDDF format - import of 3rd party UDDF files - filtering of dives by category, time frame, rating, type, and text - merging of dives - deletion of dives (a restore is not possible because Oceanic+ does not allow overwriting of deleted dives) - conversion of DataTrak, TravelTrak, and Logtrak logbooks to UDDF logbooks (UWATEC and ScubaPro dive computers) Please note: You have to have an Oceanic+ account with email/password.
