Nitrox Helper

Image
The Nitrox Helper app is a quick and easy Nitrox calculator for qualified Enriched Air Nitrox (EAN) divers to calculate the Best Mix, Maximum Operating Depth (MOD), Equivalent Air Depth (EAD), and Oxygen Partial Pressure (PPO). Always refer to your certifying agency's Enriched Air Diving Nitrox procedures to plan your dives.

Overview

I often wished for an easy to use app that would assist me when deciding what Enriched Air Nitrox (EAN) mix to fill my cylinder with for a Nitrox dive.
When my friends, my dive buddy and myself could not find an app that did what we needed I created the Nitrox Helper app.
Nitrox Helper has become our dive buddy assisting us at the dive shop.
Nitrox helper is a Nitrox calculator created for use by qualified Enriched Air Nitrox (EAN) divers.
Nitrox Helper is designed to be easy to use Nitrox calculator and the screens are designed to be easy to read and use even with cold hands.
Nitrox helper can be customized to use feet (imperial and U.S. customary measurement system) or meters (metric system).
The color scheme of Nitrox Helper can be changed by selecting a color from the available list of themes.
The calculations allow the user to select the planned oxygen partial pressure for the dive as well as the contingency oxygen partial pressure. Both the planned and the contingency oxygen partial pressure can be set by the user.
All the calculations allow the user to set the number of decimals to display for the calculation. This allows for increased bottom time when using a dive computer that permits the use of decimal inputs.
Always refer to your certifying agency's Enriched Air Diving Nitrox procedures to plan your dives.
The Nitrox Helper app does not have in-app advertising.
The Nitrox Helper app does not have in-app purchases.

Calculations

Nitrox Helper does the following calculations for Nitrox divers
Best Mix
This view helps the user to calculate the best EAN mix for a specific depth and specific oxygen partial pressure.
Maximum Operating Depth (MOD)
This view helps the user to calculate the maximum operating depth for a specific EAN mix and specific oxygen partial pressure.
Equivalent Air Depth (EAD)
This view helps the user to calculate the equivalent air depth for a specific EAN mix and a specific depth.
PPO results greater than 1.6 are highlighted and displayed with a warning.
The EAD allows a diver to use the normal air Recreational Dive Planner (RDP) table for virtually any enriched air Nitrox blend.
Oxygen Partial Pressure (PPO)
This view calculates the oxygen partial pressure for a specific EAN mix and a specific depth.
The oxygen partial pressure is required to track oxygen exposure using the DSAT Oxygen Exposure Table for Enriched Air (Nitrox).

Customize

Units
The units may be set to either meters or feet.
Color
The application has various color themes that can be applied.

Review

If you're enjoying using Nitrox Helper, please leave me a review. You guys are the reason why I love creating new apps. You guys are also the reason why I spend sleepless nights thinking about how I can improve my apps. When the late nights coding gets tough, I know I can always read the 5-star reviews from you guys to motivate me, every review makes a difference to my day!
