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.

Apple Watch Ultra (AWU) Divelog reads your recorded dive data from the Apple Watch Ultra and displays your dives. For this purpose, AWU Divelog is integrated with the Health App and the HealthKit framework and accesses the depth and temperature data stored on the phone. Your dives are listed along with the most important data, such as duration, depth and temperature, sorted by time. You may sort and group your dives by different metrics. Detailed data can be displayed for each dive. In the detail view depth and/or temperature are graphically displayed and can be shared (e.g. by AirDrop). In the detail view it is possible to swipe through the dives. In addition, overall statistics of all or selected dives are automatically displayed in the upper area of the list view. After a dive, the data is read from the Apple Watch Ultra and added to AWU Divelog. Manual updating of the list is also possible. Short surface breaks during the dive are detected and are not interpreted as separate dives. Dives can be exported as Universal Dive Data Format (UDDF) XML file (e.g. by AirDrop). The UDDF file can be imported into common dive software (e.g. Macdive and Subsurface). AWU Divelog is available in English and German. It will use your iPhone's regional units of measurement for depth and temperature (metric vs imperal). Hard Facts: - Reading recorded dive data from your Apple Watch Ultra. - List your read dives immediately after diving on your iPhone. - Statistics about your dives. - Graphical display including export for dive depth and/or water temperature. - Select individual dives. - Sort and group your dives. - Share the chart as PNG/JPG (e.g. via social media). - UDDF export of the dives
