## What is MaxOpDepth?

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 !


## Version history (last 3 releases)

### 3.0 — 2019-09-21

Bugs squished (mostly) and new devices added.

### 2.0 — 2017-11-02

The code has been simplified and starts faster on the Apple Watch. A new option to choose between 'Calculated' or 'Table' depths has been added. Calculated depths are reached purely by using the standard formula. Table depths are reached using a slight variation commonly used in dive computers and liveaboard dive boats.
More tweaks to the interface will come.
