Has anyone done any testing on other MacOS, iPadOS, iPhoneOS supported apps that have similar features/functions. While many of us have loved MacDive, unless Nick has passed the torch to someone or pops back online, it’s always good to understand our options….
When I had a MacBook Pro Retina, I used Subsurface. I also use Subsurface-mobile on my iPad and iPhone.
When it was old enough that I needed a new laptop with more horsepower, I went back to Windows (bought a Dell).
I installed the Windows version of Subsurface on my new laptop, put in my Subsurface Cloud credentials, and my log automagically appeared.
Subsurface is free, open source software. It runs on Mac, Windows, and Linux. The companion mobile app runs on iOS and Android. The Cloud storage is not mandatory, but it is free. But, if you want to do like I do and download your log from your dive computer to your mobile device while you're still on the boat ride in, then edit it on your laptop, the automatic synchronization for that does require you use the free Cloud storage.
Subsurface also has the best dive planner module I have used. I like it much better than Multi-Deco (which I do own). I have my students use Subsurface when I'm teaching the dive planning portion of tech classes.
Subsurface supports just about every dive computer you can think of. My Subsurface log has all the dives from every dive computer I have owned, which includes Oceanic, Hollis, Seabear, and a whole bunch of Shearwaters.
Log software that does not tie me to any particular brand of dive computer or any particular operating system on my desktop/laptop computer is awesome. Being free and working well is amazing!
