Although it didn't take long, the information displayed by Apple Watch is relatively simple: calorie consumption, distance, heart rate (it seems inaccurate). Therefore, Apple Watch is only suitable for junior exercisers in independent exercise and fitness functions. More professional use requires the use of professional third-party applications, such as Strava, Endomondo, Runtastic, Runkeeper, MayMyRun, etc.

If you are just a sports enthusiast who runs every day, the rich functions of Apple Watch are enough for you, but if you are a professional runner and athlete, you need a more professional fitness watch, or connect Apple Watch and iPhone to your smartphone to meet your higher requirements through a more professional third-party App.
