Getting this data off your computer isn’t trivial. Screenshot of jTrak - Does it feel like it's 1999? Yeah, we went for that kind of over the top dive computer and bought the Uwatec Galileo Luna. More advanced computers replace your entire diving console and provide a compass and wireless integration of you and your buddy’s pressure gauge. The most basic dive computers tell you your depth and warn you if you’re ascending too fast or are going to need a decompression stop somewhere along the way. One of the key components of diving is a dive computer. For the most part we’ve been very happy with our purchases and I feel like it’s made us much more comfortable when we’re underwater.
IMPORTING XML DATA INTO MACDIVE HOW TO
We purchased our own equipment relatively early in the process of learning how to SCUBA dive - shortly after getting our open water certification, thanks in large part to a nice tax rebate. Fast forward to the present day and I’ve got a closet filled with neoprene, BCDs, fins, first aid kits, and a dive log filled with all sorts of certification cards from PADI. She likes aquariums and fish and I thought it would be a fun way to do something different when we travel.

Both dives are outlined in red in the dive list.A couple of years ago I got the bright idea that I’d get my wife open water SCUBA certification as her Christmas present. Here is a screenshot of the dive data from the AWU (dive number 0) and the same dive from the Teric (dive number 31).

If you look closely at the ends of the graphs you can see the shallow swim to shore cut a bit short on the AWU graph. I must have gotten shallow enough that the watch ended the dive whereas the Teric continued recording. That is why the dive is a bit shorter on the watch with an extra shallow entry. So in this case, I was swimming in very shallow water (3-4 feet) for a few minuted to get back to the walk-out point. Edit: I realized this was one of my "swim home" dives at CCV where you do a shore return to the resort from the dive boat. This was probably just while I was at the surface anyway, as it showed a depth of 1-1.4 meters so it was probably just me getting to the ladder after my safety stop. I noticed there were a few "straggler" log entries in the exporter app from the raw data pulled out of Health.app, that I suspect account for the missing minutes. The AWU recorded the dive as being 2 minutes shorter than what my Teric recorded. What I found most interesting is that it looks like there are a lot of measurement points from the AWU data than from the Teric. I then imported one dive into MacDive and compared what the depth chart looked like compared to the data from my Teric. I used app to export the dive data from the Health app. Please be patient - this is my first attempt at writing and distributing an iOS app.

There are no guaranties that this will ever make it directly onto the Apple App Store - the App Review process is fairly stringent, but I will do my best. I wrote a quick Getting Started guide that explains what you need to run the app and how to get testing access. The app is now available for beta testing through Apple's TestFlight application. Learning all of this, I plunged headfirst into programming a simple iOS app to export the diving data out of an iPhone into a UDDF (Universal Dive Data Format) XML file so it can be imported into Subsurface or any other dive log application that support UDDF. After some research and sending my Apple Watch Ultra underwater with a few friends, I learned some things:ġ) The Apple Watch appears to be recording underwater depth and water temperature data whenever it is submerged, whether there is a dive application running or not.Ģ) It is storing those depth and temperature samples in the Apple HealthKit data store independent of whatever dive computer or gauge application is running.ģ) It syncs that data with the paired Apple phone's HealthKit data store automatically. I was bored over the holiday since I am still forcibly dry for a couple of months, so I decided to figure out how to solve this problem. There has been a lot of talk about the Apple Watch Ultra and how to export diving data from the Oceanic+ and Depth app.
