Slopes has native support for the Apple Watch Ultra's Action Button, making it one of the few third-party apps with the feature.

The Slopes app on the Apple Watch makes it quicker to start a skiing or snowboarding session if you program the action button. The Slopes app has an action button that you can use to determine your location when a workout starts.

There are a limited number of third-party apps that support the Action Button at the moment, and popular titles like Strava haven't yet implemented support. It is more convenient for users when features are built into the app.

The action button can be changed through the settings app on the Apple watch. It supports a number of native Apple Watch functions, such as launching a workout, starting the stopwatch, adding a waypoint to the compass app, and starting a dive.

Slopes is available for free from the App Store, but there is a premium subscription that unlocks all features. Slopes has Live Activity support for the Lock Screen and Dynamic Island, as well as other features, because the developers often add new features quickly.
