Dive Planner for iPhone

The Dive Planner is a very simple tool, with three vertical sliders dominating its interface: Pressure Group, Depth, and Bottom time. A fourth horizontal slider lets you set the planned surface interval between dives. Two large buttons toggle between readouts in feet or meters, and two boxes contain your pressure group after the dive, and after the indicated surface interval. As you drag any of the sliders around, the pressure group readouts change to reflect the current settings. Compared to using a dive table, this is simplicity in action—a few quick finger drags, and you can see the pressure group for your current and planned dives.
