# Sweet Dreams > Sweet Dreams is an independent iPhone, Apple Watch, iPad and Mac app that shows CGM readings as a Live Activity on the Lock Screen and Dynamic Island, on Apple Watch and CarPlay, with free critical alerts. It is not a medical device. ## Devices - [Dexcom](https://sweet-dreams.app/dexcom/): Turn on Dexcom Share with at least one follower, then sign in to Sweet Dreams with the wearer's Dexcom account. - [FreeStyle Libre](https://sweet-dreams.app/libre/): 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. - [Medtronic](https://sweet-dreams.app/medtronic/): Create a CareLink partner account just for Sweet Dreams, have it follow your main CareLink account, then sign in to Sweet Dreams with it. - [Nightscout](https://sweet-dreams.app/nightscout/): Sign in to Sweet Dreams with your Nightscout site URL and API secret. - [Eversense](https://sweet-dreams.app/eversense/): Invite an Eversense NOW follower from your Eversense account, accept it, then sign in to Sweet Dreams with the Eversense NOW account. - [Medtrum](https://sweet-dreams.app/medtrum/): Turn on sharing in EasySense, EasyPatch or EasyTouch, invite an EasyFollow account, accept it, then sign in to Sweet Dreams with EasyFollow. - [Twiist](https://sweet-dreams.app/twiist/): Invite a follower from the My twiist Portal, activate it, then sign in to Sweet Dreams with the Twiist Insiights follower account. - [Tandem](https://sweet-dreams.app/tandem/): Keep the Tandem mobile app paired with your pump and uploading to Tandem Source, then sign in to Sweet Dreams with your Tandem Source account. - [CamAPS FX](https://sweet-dreams.app/camaps/): CamAPS FX can't be read directly.

It also appears in StandBy, on Apple Watch and on CarPlay (iOS 26). - [Apple Watch](https://sweet-dreams.app/features/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. - [Alerts](https://sweet-dreams.app/features/alerts/): 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. - [Widgets & StandBy](https://sweet-dreams.app/features/widgets/): Home Screen, Lock Screen and StandBy widgets in several designs. For readings that refresh more often, pair them with a Live Activity. - [CarPlay](https://sweet-dreams.app/features/carplay/): On iOS 26 or later, your Live Activity appears on CarPlay automatically when you start driving, so readings are a glance away. - [Mac & iPad](https://sweet-dreams.app/features/mac-ipad/): Sweet Dreams runs on iPad and on Macs with Apple silicon too. You can also show your latest reading in your Mac's calendar. - [Apple Health](https://sweet-dreams.app/features/apple-health/): Export readings to Apple Health, or import glucose from Health to see stats and trends. - [Stats](https://sweet-dreams.app/features/stats/): Time in range, average glucose, estimated A1C, standard deviation, coefficient of variation, and counts of lows and highs. - [Notification profiles](https://sweet-dreams.app/features/profiles/): Separate alert settings for sleep, work, school, the gym and more, switched by hand or automatically with Shortcuts. - [Family & caregivers](https://sweet-dreams.app/features/family/): Parents, partners, grandparents and carers can all follow the same person's CGM readings on their own iPhone, each with their own alerts. One Premium subscription covers the whole family. ## How-to guides - [How to see Dexcom G7 and G6 readings on your iPhone Lock Screen and Dynamic Island](https://sweet-dreams.app/dexcom/live-activity/) - [How to see Dexcom G7 and G6 readings on Apple Watch](https://sweet-dreams.app/dexcom/apple-watch/) - [How to get low, high and critical alerts for Dexcom G7 and G6](https://sweet-dreams.app/dexcom/alerts/) - [How to add Dexcom G7 and G6 readings to iPhone widgets and StandBy](https://sweet-dreams.app/dexcom/widgets/) - [How to see Dexcom G7 and G6 readings on CarPlay](https://sweet-dreams.app/dexcom/carplay/) - [How to see Dexcom G7 and G6 readings on your Mac or iPad](https://sweet-dreams.app/dexcom/mac-ipad/) - [How to sync Dexcom G7 and G6 readings to Apple Health](https://sweet-dreams.app/dexcom/apple-health/) - [How to see FreeStyle Libre 3 and 2 readings on your iPhone Lock Screen and Dynamic Island](https://sweet-dreams.app/libre/live-activity/) - [How to see FreeStyle Libre 3 and 2 readings on Apple Watch](https://sweet-dreams.app/libre/apple-watch/) - [How to get low, high and critical alerts for FreeStyle Libre 3 and 2](https://sweet-dreams.app/libre/alerts/) - [How to add FreeStyle Libre 3 and 2 readings to iPhone widgets and StandBy](https://sweet-dreams.app/libre/widgets/) - [How to see FreeStyle Libre 3 and 2 readings on CarPlay](https://sweet-dreams.app/libre/carplay/) - [How to see FreeStyle Libre 3 and 2 readings on your Mac or iPad](https://sweet-dreams.app/libre/mac-ipad/) - [How to sync FreeStyle Libre 3 and 2 readings to Apple Health](https://sweet-dreams.app/libre/apple-health/) ## Other - [Compatibility](https://sweet-dreams.app/compatibility/) - [FAQ](https://sweet-dreams.app/faq/) - [App Store](https://apps.apple.com/app/id1644428422)
