You can log into your account at SYSTM.WAHOOFITNESS.COM to manage your account and plan your training. This portal will look exactly like the desktop version of the app (Windows, Mac) except for the ability to play a workout. You'll notice the Start Workout button is missing on the workouts.
Why have a web app that doesn't play a workout?
This portal will permit users on mobile devices to connect directly to Wahoo SYSTM to manage their subscriptions rather than through IAP on Apple or through Google Play.
