Garmin Connect tracks and analyzes health and fitness activities from Garmin devices through a smartphone app and website. Activity details may include time, distance, laps, elevation, pace or speed, heart rate, and route maps for GPS-tracked sessions. Depending on device capabilities, it can also display steps, stress, sleep, and other health or performance information. Training plans cover runners, cyclists, strength trainers, triathletes, and fitness enthusiasts. Users can create courses and custom workouts, and download courses to compatible devices. Optional connections include MyFitnessPal, Strava, and TrainingPeaks; those services may interpret activity data differently from Garmin Connect. Activity data is private by default, and users can adjust who can see it. Garmin says it does not sell personal data and shares activity data with third parties only when directed by the user. Most app and website features will be limited or unavailable if users do not upload personal data to Garmin. The free plan retains existing features and data. Connect+ costs $6.99 per month or $69.99 per year, with features varying by device.
