Scuba Diving Air Consumption Calculator is an app that allows you to input past dive(es) air, depth, & bottom time information to calculate your air consumption Surface Equivalent Rate. Then you can input the depth of your next planned dive and it will calculate your air consumption Estimated Diving Time (how long your air should last).

Air consumption Surface Equivalent Rate can be saved so it can be used at later. Additional dives and be calculated for the Surface Equivalent Rate, then when is pressed it will average with the previously stored air consumption Surface Equivalent Rate. This allows you to average multiple dives air consumption Surface Equivalent Rate.
The button can be toggled back and forth between and . This is accomplished by long pressing the / button.

The menu has the following items:

About: Information about the app.

Usage Tips: Tips on how to use the app.

Clear Stored Values: Clears the stored air consumption Surface Equivalent Rate.

Imperial (English) / Metric: Set the app to use either Imperial (English) or Metric units.

Set Est Air Usage: The amount of air you plan on using for you next dive. The app defaults to 2200 PSI. This is based on 3000 PSI starting pressure then subtract 800 PSI target ending pressure. This number can be changed for different estimates depending on the type of dive you are planning.

Clear Screen: Clears the inputted data from the screen.
