5/5Most versatile Dive log
I have used Subsurface for years and it has every feature I would ever need. I can’t specify what is the best feature because it has many. The top 2 are first it’s compatible with most dive computers and second it works on most pc OS and mobile devices.

5/5Awesome free dive log
For a free dive log app this thing is pretty sweet! The UI is not the prettiest thing you’ll ever see, but what matters is the data and content - and this app does all of that well! I first download the Mac app on my MacBook and I find that it’s easier for me to upload all my dives directly to my MacBook first, and then sync them with the cloud. Once you do that they all become visible here in the mobile app for easy viewing and editing. I hope the developers keep this app current because it’s great!

5/5Best dive log ap
This is the best dive log app. Ive tried several including paid apps and was so happy to finally find this one. It does everything I want. Able to Download complete dive profiles off the dive computer, mark dive sites with gps. Lots of cool features. Ap is still in development and takes a little fiddling to get used to but works great for me. Developers are accessible to help with troubles or questions. Recommend to all my dive friends!

4/5Awesome for a free dive log
To the developers: great job on providing divers an inexpensive method of keeping their logs up to date across multiple platforms. The existing functions meet my basic diving needs, however there are several suggestions that I think would be very benificial, which I assume you all may or may not have heard already. Certification tracker: It would be amazing to have a function where we could quickly look at our records of past diving certifications, instead of divers having to carry a physical copy of their diver ID card everywhere they go. Please consider this! Uploading media via mobile device: this would be an absolute killer feature if you all could incorporate it. Even if it’s just the ability to upload a few photos or a quick clip to a specific dive. It would allow divers to keep a memory jogger of where they went diving and with whom. Syncing functions: I was fairly confused the first time I used the syncing functions via the desktop and mobile app, but eventually figured it out. However, I could see someone making the mistake of syncing from the cloud to their mobile device when in fact they want to do the opposite (mobile to the cloud, especially after manually logging dives on the mobile app during the time they were out of cellular data range). To prevent any confusion, I would recommend renaming the syncing functions so they are a bit more clearer to the lowest common denominator. PDF print out clarity: not sure if this is just my computer or a function you could tweak in your software, but the pdf print out was slightly blurry. I could see large pixels when I attempted to print my current logbook. Other than that, keep up the good work! I’ll definitely be using this app to log my future dives.

5/5Best overall dive log app out there...
Open source app that is compatible across multiple platforms and provides FREE cloud storage to support synchronization across all of your platforms. Plays well with just about every dive computer out there. I was also able to import previous dives from a OEM application Super support available via forum.
