Beautifully designed dive log app
This is the first dive log app that not only looks slick and stylish but is amazingly user friendly… Really beautiful and definitely motivates me to keep logging my dives.
No more wet paper log books
Finally I can get back to logging my dives in a pretty digital book.
Excellent
I've tried many different apps and been frustrated by all of them. This one is smooth… and keeps everything organized. Finally.
