I got the Oceanic+ Dive Housing to go with this app (and the one on my Apple Watch). I will say that as a backup dive computer, the watch version is competent. I like how it essentially does your dive log for you. The app also does an amazing job of color correcting underwater photos, again, when it works. Now for the downside. I used this for the first time while diving in Hawaii. On the first dive, I recorded two videos, 14 minutes and 26 minutes. I got back to the boat, opened up the dive housing, and nothing. None of the super cool video I took of sea turtles was there. I emailed customer support, but got zero reply. On the second dive, I took numerous photos, and they were all there when we got back to the boat. Unfortunately, for the third dive, two minutes into the dive, the app stopped responding. Again, lots of turtle photos missed. So, to recap, it has a 66% failure rate, which in my book is unacceptable. Finally, for the photo color correction, you cannot batch adjust the photos. You have to adjust each photo individually, save each individually, and every 5-10 edits, the program crashes, requiring you to sift through the thumbnails to figure out where you left off after each crash. Really not ready for release, and I suggest avoiding this product.

It should be made clear that the dive computer functionality has two components: the Apple Watch Ultra provides all the sensor data, and the Oceanic+ app displays the information and the logs. The Apple Watch Ultra is phenomenal. The app is great when it works. However, it doesn’t work all the time. my app was set to launch the dive automatically when the watch contacts the water. Only that it didn’t. Less than a minute after we started to descend I’ll look at the watch just to see it was asking me to press the button to confirm that “I am fit and ready to dive.“ I tried to press the button, but by now it was in water lock mode, so that didn’t work. so basically the stupid app provided no information whatsoever during the entire dive. and just like that, in spite of having a nice watch with all the sensors, in spite of having purchased the subscription for the Oceanic+ app, I was back into the dark ages of diving with no information about the descent and most importantly, ascent rate, no information about the depth, no decompression time, etc. And of course no safety stop information. Overall, a really frustrating experience!!!

I was excited to be able to try the app with the Apple Watch ultra. I used it as my backup dive computer on a trip to little cayman. The display is very readable and worked well comparing it to my main dive computer a Petrel 3. The issue I had was when I placed the app into the dive mode and did a giant stride into the water, the app apparently switched back to surface mode before I submerged and stayed locked in the surface mode ignoring the dive. It would be nice if the depth exceeded a certain amount ( 1 foot, 5 feet, 10 feet ? ) that it would switch back to the dive mode automatically. I missed logging 3-4 dives because of this issue. The Petrel 3 worked fine thankfully having all my data. My current issue is now my watch won’t sync with the app. I have deleted, reinstalled, given all permissions, etc. without any sync happening. It could be the iOS version or updates to the app, I’m not sure but it runs against Apple’s saying “ It just works” well this app just doesn’t work well. The latest update does allow my watch and phone to “see” each other. I now get a brief message that a sync is occurring. The issue I have now is that after the sync, since I had deleted and reinstalled the app, now after the sync, my watch does not show any dives in the log where my phone app does. I would expect a sync ( unless this is only a one way sync ) to result in the log on my watch and the log on my phone app to be the same.
