Yes. Glyco is free on iPhone and on the web, for runners, cyclists and triathletes.
Is there an Android app?
On Android, Glyco runs in your browser at glyco.co.za/app. It is the same app, with the same account, and you can add it to your home screen.
Do I need an account?
Not to plan a race: the race planner works in full without one. You sign up to save your plan and to connect Strava or Apple Health.
Does it work with my watch?
Your sessions come in from Garmin and other watches through Intervals.icu, and from Apple Watch through Apple Health. A planned session can go back to your watch: Apple Watch, Garmin, a .fit file or Zwift.
