DiveLogDT is a full desktop digital Scuba Log Book and a companion application to Dive Log for iOS. DiveLogDT allows you to edit and manage your digital scuba diving logbook as well as Download a select number of dive computers. Currently we support downloading some dive computers from the following manufacturers:

:: Liquivision
:: Pelagic Pressure Systems (Aeris / Aqualung / Genesis / Oceanic / Sherwood / Tusa)
:: Mares
:: Heinrichs Weikamp

Many models require a manufacturer specific cable or dongle in order to download it. Dive computer models supported change frequently so please check our website to determine if your model is supported. If it is not, please drop us a line and let us know which one you would like added.

If we don't support downloading your dive computer, you can import dive computer profiles and other dive information from several other logbook formats, and sync your logbook to your mobile device using Dive Log for iOS. (See website for supported 3rd party applications and file formats)

DiveLogDT works in both metric and imperial, shows statistics about your diving history, keeps track of all your scuba equipment, shows buddy and personal information, and dive site details. View all your Dive Site Locations on a world map if GPS locations have been entered. Lookup and fill in the GPS locations of your dive sites using the web - lookup via the Dive Site name with 2 different web services, or use a world map to point to it's exact location. Keep details about your dive trips and the shops that you dive with. Categorize each of your dives by any "type" of your choice. Know how many dives you've done with each piece of Equipment and when it should be serviced. Remember which pieces of your photography equipment you used for each dive too!

Extensive Statistics are available for your logbook including dives by Site, City, Country, Buddy, Type, Equipment, Shops, and Trips. Also get a chronilogical view of your dives by year and by month. Select more than one dive at once and compare the dive profiles between dives. If your dive computer supports it, you can also view Temperature, Tank Pressure, No Decompression Limit, Remaining Bottom Time, and Heart Rate profiles. Tech divers will be able to view tank switches and decompression obligations on the profile. Enter tank pressure and size information to be able to view your SAC or RMV rate for the dive.

If you don't want to take your desktop computer with you on a dive trip, then just take your mobile device with you on the boat and log all your dives using Dive Log for iOS. Use it to add your site GPS information, take location photos and save your weight and tank information etc, and enter buddy details (including signature) right away. Then when you get home, use DiveLogDT to *merge* your dive computer information into what you have already logged! Then sync your logbook back to your iOS device. Full synchronization is supported so that if you make changes in both places, they will all be preserved (per dive). You can also sync your logbook using a Cloud based service between your iOS devices and your macOS devices.

You can also Import dives from many other formats and merge the information into what you have logged. Export your dive profile information into DL7 format for importing to other websites. Many places support our logbook format so you can export to them directly as well.

We cannot reply to reviews so if you have any feedback for us, please email - we always reply.

Ratings and Reviews

Best app for UWATEC Galileo sync


To the best of my knowledge, this app is the only one for Mac to sync Galileo DCs via IRD.
Work seampless with USB 7780 dongle.
Unlike other apps, it is also compatible with Os 10.9+
Owner is very supportive with technical assistance and general guidance.
Thanks for nice app!

Working well now


Update fixed Pelagic crashed, so returning to 4 stars. I wish there was more statistics, but otherwose very good log system.

Developer Response

Yes, you are right, the App did crash for a very small number of users - those Downloading Pelagic dive computers and were *not* using the FTDI kernel device driver. (Most Pelagic users do). There was a new version out the following day that fixed this problem. I hope you will consider changing your review to reflect the "overall" quality of the software and support and not a "1 day" problem.

Finally a Mac app than can download my Uwatec Computers!


Ok, so the interface still needs some help, but I finally have an app that can download my Uwatec computers natively in OSX. For too long I was using VMWare Fusion and Windoze software to download my computers, with this app, all that is not needed. I have a MOSCHIP MCS7780 IrDA device and it works fine with this app and with Mountain Lion.

I love the fact that I can sync it with my iPad and iPhone, in fact I have been using the iOS version of this app for a while now. It has been a great way to have my logbook with me all the time and store my c-cards as well.

I can't give five stars at this time because there are some things that could be better. I would love a little more flexibility in printing and layouts. There are some clunky things when editing log entries, but over all, the fact that I can use this will all of my computers makes me really happy.
