Altimeter Watch [iPad]

Altimeter Watch is designed to take advantage of the GPS in your Apple Watch Series 2 or 3. It provides you with a graph of your altitude history.

There is an included complication that will periodically update to show your most recent altitude.

Altimeter Watch also includes oxygen monitoring features! The real-time altimeter display on the watch will now show you how thin the air is, as a percentage of the oxygen available in the air at sea-level.

There is also an oxygen percentage history graph, to visualize how much oxygen you've had available in the recent past.

This oxygen percentage will also show up in some complications. (O₂@SL - Oxygen at Sea-Level).

To allow for more frequent GPS data collection, this app includes a Workout Mode. When recording a Workout, the Altimeter Watch app will stay in the foreground, and show your altitude history every time you raise your wrist.

When Workout Mode is stopped, your workout can (optionally) be saved to Apple Health.

Using Workout Mode decreases battery life, please only use it when you need detailed altitude data.

The app also includes a companion iPhone app that allows you to inspect the data points collected by the Apple Watch in detail.

Altimeter Watch only works with Apple Watches that are equipped with built-in GPS. This app does not work with Apple Watch Series 0, or 1. It also does not work with iPads.

Altimeter Watch is most accurate when your watch has a clear view of the sky.

Note: The Altimeter Watch oxygen monitoring features are estimates only, and may be inaccurate. Altimeter Watch does not at any time guarantee a healthy or safe breathing environment. Users of Altimeter Watch should have property training, professional supervision and a backup source of oxygen available at all times, especially when either above 300m of elevation, in poorly ventilated spaces, in locations where dangerous gases may be encountered, or any combination of these scenarios.

GPS altitude data can be inaccurate indoors, and in enclosed vehicles such as aircraft. Altimeter Watch is not to be used as a primary source of data for aviation, navigation, or surveying.
