Hunch
Hunch support
Hunch shows "No data" for something I track
Open the Settings app → Health → Data Access & Devices → Hunch, and turn on the types you want Hunch to read. In Hunch, the Data tab shows what's arriving and has a setup guide for each device.
Insights or experiments say "not enough data"
Scores compare you with your own recent normal, so they need a couple of weeks of data. Experiments need at least 5 measured days in each week.
Restore Hunch Pro on a new iPhone
Open Hunch → Settings → Hunch Pro → Restore purchases, signed in with the same Apple Account.
Cancel a subscription
Open the Settings app → your name → Subscriptions → Hunch, or use Manage subscription in Hunch's Settings.
Widgets show an old time
Widgets show the numbers from the last time Hunch was opened, because Apple Health can't be read while the iPhone is locked. Open Hunch and they update.
