Dive Log is designed to work either as your primary SCUBA diving logbook application or in conjunction with compatible 3rd party desktop logbook applications. You can use Dive Log at the dive site or on the dive boat to capture the information about the site while it is fresh in your mind (or your dive guide's mind). You can even capture the GPS coordinates of the dive site using the built in location services of your iOS device. Details about your actual dive can be added immediately after your dive or at the après dive event and later be saved to your desktop computer. The dive buddy feature is fully integrated with Contacts on your iPhone or iPad, letting you capture information about your newest dive buddy or quickly add an existing buddy to a particular dive. The dive data and statistics features let you have an immediate answer the next time your dive guide asks how much weight you used on your last dive or have all the information you need about your dive history when you fill out that next dive waiver. Metric and Imperial values are supported for all appropriate logbook fields. You can easily enter values using the appropriate units for the situation and view them in your preferred measurement system. You can even explore detailed dive profiles from popular dive computers that you download with your desktop software and later upload to Dive Log on iPhone/iPad. Dive profile data can also be transferred directly from certain dive computers directly via Bluetooth or using a supported Bluetooth accessory and an associated in-app purchase.

On Windows, Diving Log 6.0 (www.divinglog.de) is fully integrated with Dive Log on iPhone/iPad and has built in synchronization. Diving Log 6.0 has extensive support for importing data from dive computers and other dive log applications.

On Mac OS X, logbook information can be imported to Dive Log on iPhone/iPad from a number of compatible applications using the free Dive Log Manager application available from More Mobile Software (www.moremobilesoftware.com/divelog-sync). DiveLogDT (available on the Mac App Store) can be used to directly import a number of dive computers and file formats and can synchronize with Dive Log on iOS.

Dive data can be directly downloaded on a Bluetooth LE (Bluetooth 4.0/5.0) compatible iPhone, iPad or iPod touch from Bluetooth LE capable dive computers such as the Suunto EON Steel, Suunto EON Core, Suunto D5, Scubapro Galileo 2 (G2), Aladin Sport (Matrix), Aladin H (Matrix), G2 HUD, Aladin A1, Shearwater Teric, Peregrine, Petrel 2, Petrel 3, Perdix, Perdix AI, Perdix 2, NERD 2, Oceanic VTX, Pro Plus 4, Geo 4.0, VEO 4.0, Aeris A300CS, Aqualung i300C, i330R, i550C, i750TC, i770R, Apeks DSX, Sherwood Wisdom 4, Mares Genius and certain heinrichs weikamp OSTC computers as well as the DiveNav Inc. bluebuddy and Tech Buddy dive logger accessories. Supported Bluetooth LE accessories are available separately.

Mares Bluelink Pro is a Bluetooth LE accessory by Mares and available for purchase separately (www.mares.com). The Bluelink Pro allows you transfer dive data from certain Mares dive computers (Puck Pro, Smart, Smart Air, Quad and Quad Air) directly to Dive Log on your Bluetooth LE compatible iPhone, iPad or iPod touch.

Dive Computer Buddy (aka DCbuddy) is a Bluetooth LE accessory by DiveNav Inc. (note that the DCbuddy itself is no longer available). The DCbuddy allows you transfer dive data from certain dive computers (including models from Suunto, Oceanic, Aqualung, Aeris, Sherwood, Tusa and Mares) directly to Dive Log on your Bluetooth LE compatible iPhone, iPad or iPod touch.

Exactly what I was looking for!

After trying out several applications on both iOS and PC, this is the one I use (along with Diving Log 6.0 on a Windows PC to capture my dive computer data). I love that I can start the log on my phone at the dive site in order to capture things like GPS location, info I want to remember, and a signature from a dive master or buddy, without having to manually enter any of the data that my computer automatically logs. Then, once I'm home, I download my computer to add the dive profile, temperatures, air consumption, etc. and merge the two sets of info together.

The statistics are really fun. Want to know how many times you've dove at your favorite spot or with a certain buddy? How many hours you spent underwater last October? Your deepest / longest / coldest dive? How many dives one of your exposure suits survived? The statistics feature can not only answer these questions, but will also link to each of the associated dives.

You can also use this app to keep track of all of your equipment, including pictures, serial numbers, warranty info, service schedules (with optional reminders), and it can track dive counts for each piece. It also stores certification info including images of C-cards.

Love this app!

2 Thumbs Up

I have used this app for years, primarily on my iPhone but also use it on my laptop to sync up with my dive computer for depth profile, times, temp, etc. I really love this app, it is so easy to use and you can put in whatever level of detail you want and leave the others blank. I update after almost every dive in 1-2 min so I never get behind. It really comes in handy when I am returning to a dive center and need to know what I was using for weight, who you dove with or the sites you liked best, my girlfriend runs a paper log and unless it’s <20-30 dives back she never has the info with her.

Keep up the good work Greg, your a legend for keeping this app going.

Super responsive developer

I have tried a couple electronic log books and this is my favorite by far, though I have been manually logging my dives as my old computer didn’t support downloads.

I recently bought a new computer (Aqualung i550C) and posted a note on the support forum asking if anyone had got Dive Log to work with it via Bluetooth download yet. The developer contacted me and within a couple days had a working beta of the software that supports my computer. Amazing! Thank you for a great product and top notch support.
