WorkOutDoors is an advanced workout application designed specifically for Apple Watch users. It is a perfect companion for individuals who love running, cycling, hiking, and other indoor or outdoor activities. With a total of 38 different activity types, the app offers a vast range of workout options. WorkOutDoors allows you to configure multiple screens with metrics from over 600 data fields and graphs. All workouts are saved to Apple's health system and are viewable in the Health & Fitness apps. You can export workouts as FIT/TCX/GPX files or automatically upload them to Strava, even from the watch.

The app offers dozens of alert types, including mile/km notifications, high heart rate, low speed, and zone changes. You can configure which metrics are displayed and/or spoken for an alert. The GPS signal strength is shown before starting a workout, so you can wait for a good signal. Additionally, you can create your own interval schedules, set a target pace and see how far ahead or behind you are, and analyze workouts in great depth on the iPhone app. WorkOutDoors supports watchOS 9 running metrics, including power, ground contact time, and vertical oscillation (only available on recent models of watch).
