Love it (but loose the sliders)
I love this ap!
My one and only complaint is that it uses sliders instead of having an actual keypad to enter your times and depths. As anyone with an iPhone knows it's often notoriously hard to land a slider exactly where you want it and this program is no exception. Example: After my wife and myself both spent several minutes each trying to land the time slider exactly on 30 minutes we ended up having to settle for either 29 or 31, it just wouldn't land on 30. On the depth slider she finally got it to land on 25 after like 4 minutes of carefully trying to move it only to have it jump to 27 anyway as soon as she tried to take her finger away.
While it's not a complaint, A suggestion for the future would be to allow you to save the plans you have made, maybe give them a name, so you can look back at them later such as back in the hotel room later that night when on a diving vaccation. Being able to save and edit (including eventual deletion) of a couple of days worth of plans would be awesome, especially when On a SCUBA diving vaccation.
