Racefully integrates with Strava. Any activity that you record on Racefully will show up in your Strava account - and vice versa. You'll also get any activities you record on other platforms or wearables that sync to Strava.
Racefully for Android doesn't currently have the ability to record activities in the app, so connecting to Strava is the only way to bring activities into Racefully.
To turn on the integration:
iOS: choose Settings in the menu, then Sync with other apps. If you turn on the Strava integration you'll be taken through the steps to sign into Strava and connect your account.
Android: Tap Connect with Strava on the home screen. Turn on the Strava integration to be taken through the steps to sign into Strava and connect your account.
That's it - you're all set.
