Sweet Dreams for FreeStyle Libre 2, 2 Plus, 3 and 3 Plus: Live Activity, Apple Watch and alerts
Invite a LibreLinkUp follower from the FreeStyle Libre app (your own email works), accept it in LibreLinkUp, then sign in to Sweet Dreams with the LibreLinkUp account. Sweet Dreams then shows your readings on your Lock Screen, Apple Watch, CarPlay and Mac, with free alerts.
- Works with
- FreeStyle Libre 3, FreeStyle Libre 3 Plus, FreeStyle Libre 2 (where it uploads automatically), FreeStyle Libre 2 Plus
- Sign in with
- a LibreLinkUp account (not LibreLink)
- Updates
- The graph in the app refreshes every minute. The Live Activity refreshes every 5 minutes, or every minute on request.
- Not supported
- Lingo; Libre 2 in regions where it doesn't upload automatically to LibreLinkUp
Sweet Dreams reads from LibreLinkUp, so it works with any Libre sensor that uploads to LibreLinkUp automatically. Libre 3 does this in every region; Libre 2 only in some.
How to connect Libre to Sweet Dreams
Already follow someone in LibreLinkUp? Skip to the last step.

Good to know
- One LibreLinkUp login can follow several people, and Sweet Dreams lets you switch between them.
- The graph in the app refreshes every minute. For a Live Activity that also refreshes every minute, tap Request frequent refreshes in Settings → Live Activity & Dynamic Island.
- The graph shows up to 12 hours of history, which is what LibreLinkUp provides.
- If sign-in fails, Sweet Dreams shows the reason LibreLinkUp gives. The most common cause is using the LibreLink login instead of LibreLinkUp.
What you can do with Libre
How to see FreeStyle Libre 3 and 2 readings on your iPhone Lock Screen and Dynamic Island
Your latest reading, trend and graph on the Lock Screen and in the Dynamic Island, refreshed every few minutes, far more often than widgets. It also appears in StandBy, on Apple Watch and on CarPlay (iOS 26). Premium
How to see FreeStyle Libre 3 and 2 readings on Apple Watch
Three ways to see readings on your wrist: a frequently refreshed Live Activity in the Smart Stack, complications for every watch face, and a watch app with a graph. Premium
How to get low, high and critical alerts for FreeStyle Libre 3 and 2
Free alerts for very low, low, high, very high, fast rises and drops, and missed readings. Each can be Regular, Time Sensitive, or Critical, which sounds even when muted and overrides Focus modes. Free
How to add FreeStyle Libre 3 and 2 readings to iPhone widgets and StandBy
Home Screen, Lock Screen and StandBy widgets in several designs. For readings that refresh more often, pair them with a Live Activity. Premium
How to see FreeStyle Libre 3 and 2 readings on CarPlay
On iOS 26 or later, your Live Activity appears on CarPlay automatically when you start driving, so readings are a glance away. Premium

Sweet Dreams runs on iPad and on Macs with Apple silicon too. You can also show your latest reading in your Mac's calendar.
How to sync FreeStyle Libre 3 and 2 readings to Apple Health

- Everyone signs in with the same sharing account for the person you look after. Your device's page says which account that is, for example LibreLinkUp for FreeStyle Libre or the wearer's Dexcom account for Dexcom.

- Use the Message Group button on the Home tab to ping everyone following the same person, or to let them know you're taking care of it.
Common questions
Do I sign in with LibreLink or LibreLinkUp?
LibreLinkUp. Sweet Dreams signs in as a follower, so the FreeStyle Libre (LibreLink) login won't work.
Does Sweet Dreams work with Lingo?
No. Lingo doesn't share readings through LibreLinkUp.
How often do Libre readings update?
The graph in the app refreshes every minute. The Live Activity refreshes every 5 minutes by default, or every minute if you request frequent refreshes.
Can I follow more than one person?
Yes. If your LibreLinkUp account follows several people, you can choose who to see in Sweet Dreams.
Free on the App Store for iPhone, Apple Watch, iPad and Apple silicon Macs.
