First, it doesnt always capture your information; you can log a dive, and it doesnt show up - there is no "Save" function when you log the dive, then if you go back to check, your recently logged dive is not there. So, you log it again in hopes that it works, then if by chance it does work, you end up with the same dive logged twice; but there is no EDIT function on the app. If you view your logged dives, for tank info, it shows your tank 1 type, but tank 2 beginning/ending pressure (odd since you didnt enter it), and not many dive with two tanks at once (I dont dive with a double rig). Overall, this seems to have been designed by a freshman app designer. PADI sometimes makes odd decisions...
