Once this is on, your eligible activities count in Harry's automatically. No screenshots or links.
Harry's reads runs, rides, swims, workouts and calories from Apple Health. Not every challenge uses this data; each challenge in the app shows what it tracks.
Open the COROS app on your phone.
Tap Profile in the bottom-right corner.
Scroll down and tap Settings, then 3rd Party Apps.
Tap Data Sync.
Tap Apple Health in the list of apps.
Tap Connect and allow access on the permission screen. Once connected, Apple Health shows a green tick and a last sync time back in the list.
Done? Back in Harry's, open Settings > Data & Syncing. The Last sync time updates within a few minutes of your next activity.
