Common questions

Readings from my sensor aren't showing. Companion reads them from Apple Health. Open Profile → Apple Health and make sure Blood Glucose is allowed, then pull down on Home to sync. Some sensor apps write to Health with a delay of up to three hours.

A reminder didn't arrive. Check that notifications are allowed for Companion in Settings. Reminders re-register automatically the next time you open the app after allowing them.

Where is my data? On your phone. Export it any time from Profile → Prepare data export. Companion doesn't sync to iCloud yet, so before moving to a new phone, use an encrypted iPhone backup (iCloud Backup or an encrypted backup on your Mac), which carries the app's data across.

How do I cancel Companion Plus? Settings → your name → Subscriptions, or from the Plus screen in Profile → Manage subscription.

I bought Plus on another iPhone. Open Profile → Companion Plus and tap Restore purchases, signed in with the same Apple Account.

How do I delete my data? Profile → Delete all data removes everything Companion stored on the phone. There is no Companion account, and we hold no copy of your journal.

My Apple Watch doesn't show my reading. Open Companion on the iPhone once so it can send the latest page to the watch, and keep the watch near the phone. The watch app installs with the iPhone app; see Profile → Watch, widgets & shortcuts.
