This provides a simple graphical tool for scuba divers calculating maximum operating depth. It provides both iphone and Apple Watch versions. It's important to remember that while scuba diving, it is always recommended to double check your calculations with reference to the relevant diver tables. While this app may prove useful, it's no substitute for using your own brain and being fully aware of the dangers of scuba diving. Enjoy !

About

Nitrox Virtual Analyzer

Features
Read full description

Our Nitrox Virtual Analyzer is the first of its kind in the world. It gives you the ability to safely and conveniently learn how to operate a Nitrox Analyzer, used for scuba diving. Without having to visit a dive center to borrow and analyzer and cylinder of Nitrox or go to the expense of purchasing an analyzer & Nitrox cylinder. The app allows you to make mistakes in safety, and let the app guide you through the correct way to calibrate and analyze a Nitrox gas mix. The app has been written by experienced diving instructors, and closely resembles a real Nitrox Analyzer in both its look, operation, and response. So when you actually use a real Nitrox analyzer you will be familiar with its use. This app gives you the ONLY way to get certified by any diving agency for Nitrox without attending a class! A requirement for most Nitrox courses is to analyze a Nitrox mix, to obtain certification; if you haven't done that you should consult your instructor/dive center if you have correctly fulfilled the requirements of your course. NOTE: This app is for simulation purposes only, it CAN NOT actually measure the oxygen percentage in a gas. There is no Oxygen sensor in your mobile device!
