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:

:: Atomic Aquatics
:: ScubaPro/UWatec (IrDA, USB, and BLE)
:: Suunto (USB and BLE)
:: Shearwater Research (Standard and BLE)
:: Liquivision
:: Pelagic Pressure Systems (Aeris / Aqualung / Genesis / Oceanic / Sherwood / Tusa)
:: Mares
:: Heinrichs Weikamp
:: Cressi
:: Ratio
:: Divesoft
:: Garmin

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.

If you have any questions or feedback for us, please email - we always reply.

Awesome Software

This software was the answer I was looking for! The ScubaPro support software is very limited on the Mac and has zero integration between devices. This allows me to keep track of my dives in detail while also getting rid of my traditional log book. In addition, their customer support is fantastic! Thank you!

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!

the real puce navel ,

Finally found it!

I tried a few other free apps and programs, including Suunto’s own software. They all sucked.

This one rocks!

Integration was fast and easy from both dive computers that my daughter and I have (Zoop and D4i).

I love the fact that I can use the iOS app or the desktop to get pretty much the same edit/entry capability.

I was even able to import dive log from one of those other applications (one of the ones that you have to have a degree in UNIX to actually get data off the Zoop).

Loving this app! Interface is clean and easy - printing is intuitive and has readable, appealing layout.

Would love to see the following improvements:

Remembered inputs on more fields (like you do for Site, Trip, etc.).
Hover over information on the graph
Option to copy Environment & Equipment data from another dive (since the weather, my equipment, diving partner, etc is likely the same on a dive an hour later)
Faster (one-click) integration to iOS device once it’s paired
How about an online catalog of equipment that you can search to fill in the details (yeah, I know that’s a reach)
