WorkOutDoors is the most advanced and most configurable workout app for the Apple Watch. It's perfect for running, cycling, hiking and any other indoor or outdoor activity. Note: WorkOutDoors requires an Apple Watch Series 4 or later. It is not necessary to have your iPhone with you during a workout. The app uses Apple’s workout system, so all workouts are saved to the Health system. However it also provides many extra features over Apple's app, such as: - a super-smooth vector map that can be shown during a workout; - multiple configurable screens with metrics and graphs from a pool of 800+ data fields; - route files can be imported and used for navigation (including turn by turn directions); - dozens of configurable alerts (e.g. every mile; high heart rate; low pace; off-route etc); - interval schedules can be created using the larger screen of the phone app; - climbs and descents are supported with notifications and on-screen data and graphs; - waypoints can be created, navigated to, and exported; - use shortcuts to associate operations with gestures (e.g. double tap to hear configurable metrics); - compare pace against a target or a previous workout (using metrics and a dot on the map); - show zones for pace and power as well as heart rate (with optional coloured backgrounds); - auto-pause is available for all outdoor activities; - shows GPS and heart rate before starting a workout, so that you can wait for good signals; - configure distance and pace for running / walking to come from Apple’s pedometer or from GPS; - workouts can be exported in FIT / TCX / GPX files, or automatically sent to Strava; - workouts created by the app can be analysed in great depth in the iPhone app. The app also has many more features. The map is a particular highlight. It uses OpenStreetMap, which provides worldwide coverage and includes the trails necessary for outdoor workouts. It also has several features that help you navigate during a workout: - maps can be smoothly panned and zoomed, and can rotate according to the compass; - a breadcrumb trail of your whole route is displayed on the map during the workout; - topographic data can be shown, with configurable contour colours and hill shading; - map-only mode is provided for when you don't want to start a workout and just need a map; - a circular scale is shown when you zoom, making it easy to see the distance to features; - maps can be stored on the watch for use when offline (they are downloaded as required if online); - a red compass points north and a green compass points to the start; - choose a waypoint to see a compass and distance to it in the corner of the map; - you can also navigate to waypoints on the map, such as hospitals, sights, cafes etc. If you load a route from a GPX / TCX / FIT file then navigation is even easier: - your position is shown on an elevation profile of the route; - the remaining distance, time and ascent can also be displayed; - you can get alerted when you go off-route; - when off-route then a compass is shown which points to the nearest part of the route; - if the route contains turn by turn directions then these can be used like a sat nav; - if there are no directions then the app can use “bend detection” to generate them; - the next direction is shown as an icon and distance in the corner of the map; - the map can automatically zoom in when you are approaching a turn; - you can use shake gestures to hear the distance to the next turn or the end of the route; - routes are coloured by gradient: from red for steep uphill to blue for steep downhill; - you can configure what information is displayed during a climb or descent. All this is included for a single one-off payment. No extra in-app purchases or subscriptions are required (although there is a completely optional in-app tip jar which was requested by long-term users). If you own an Apple Watch and do any form of exercise, then WorkOutDoors is the app for you. Give it a go!

Verdict
The clearest difference is price: Heart Analyzer at Free against WorkOutDoors's $8.99. Heart Analyzer also leads on update cadence (weekly vs every 3 months) and ratings volume (22K vs 1.7K). WorkOutDoors's advantage is chart position (#6 vs unranked) and iOS requirement (12.0 vs 17.5). On rating, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Heart Analyzer is free to download; WorkOutDoors costs $8.99 up front. Heart Analyzer sells 7 in-app purchases, starting at $3.99 per month and WorkOutDoors sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for Heart Analyzer against 4.7 for WorkOutDoors. That said, the two scores are not equally well evidenced: Heart Analyzer has 22K ratings behind it against 1.7K, so its average is the more settled of the two. Written reviews are what separate them: 84% of Heart Analyzer's written reviews are positive against 88% of WorkOutDoors's.
Heart Analyzer ships an update weekly, WorkOutDoors every 3 months. Both last shipped on October 24, 2026.
