It is strongly recommended that Styders setup a PowerCenter account. With an account you get:
1. Access to Stryd's PowerCenter platform, the best tool to analyze your data and track your improvement.
2. Ability to manage your Stryd device: updating the firmware, setting weight and height, checking battery level, etc.
3. Access to the full-featured Stryd app on your phone and Apple Watch, which allows you to record your run if you do not own a sports watch.
However, if you own a Garmin or Suunto watch, you can avoid using the Stryd platform and app. You will not be able to update firmware to keep your device up to date, and you will not be able to adjust height and weight.
