Quick checklist (top gotchas)

  • FreeStyle Libre app shows current readings.
  • LibreLinkUp invitation is accepted.
  • Both accounts are in the same region.
  • Phone has reliable internet + background data allowed.
  • Device time/timezone are correct.

What you need

  • FreeStyle Libre app set up and actively receiving readings.
  • A LibreLinkUp account with a connection to the wearer’s Libre account.
  • Both accounts must be in the same region (region mismatch is a frequent blocker).

Step-by-step setup

  1. Create/verify the wearer’s FreeStyle Libre app account. Confirm current readings appear in the FreeStyle Libre app.
  2. Create the LibreLinkUp connection. From the wearer’s app, invite a follower via LibreLinkUp (email invitation). On the follower side, install LibreLinkUp, create/login, and accept the invitation.
  3. Sign in to your secondary display/app. Log in using the LibreLinkUp follower account (not the wearer’s primary app session). Select the correct person from the connections list (if multiple people are followed).

Troubleshooting (most common issues)

  • No invitation received: confirm the email address is correct, check spam, and resend from the wearer’s app.
  • Can’t connect across countries/regions: LibreLinkUp is region-bound; both accounts must be in the same region.
  • Multiple connections: ensure you selected the correct followed user.

See the Troubleshooting hub for cross-provider fixes.

FAQ

Can I sign in with just the FreeStyle Libre app account?
Most secondary display integrations use LibreLinkUp’s follower model rather than direct sign-in as the wearer.
