Choose a follower app
A follower reads data already in Nightscout. First verify the source upload and a new reading in the site’s browser view, then configure viewing access.
Documented connections
- Android: xDrip+ Nightscout follower or Sugarmate by Tandem.
- iPhone: LoopFollow, Sugarmate, or xDrip4iOS follower with the app-specific instructions and version limits on that page.
- Watches and home displays add another layer after the source connection.
Sugarmate by Tandem is available on Android, iOS and the web. See Tandem’s official getting-started page for downloads, and check the Sugarmate guide for Nightscout connection requirements.
Give viewing access
For a private site create a separate readable token for each recipient/device where practical. Use the app’s documented token or URL format. Do not reuse an upload/admin credential simply because a field is called “password.”
Verify
Compare a new reading, its time and units with Nightscout. Then check normal background updates and the app’s own notification/alert test functions. Cloud and follower delays vary; an app is not guaranteed to deliver every alarm.
Modern follower apps may also offer remote-control features. Viewing setup does not authorize or configure those actions; keep them separate.
