Which glucose sensors work with Ask My Glucose?

The entire current FreeStyle Libre lineup (Libre 2, Libre 2 Plus, Libre 3, Libre 3 Plus) through LibreLinkUp sharing, and the Dexcom lineup (G6, G7, G7 15-Day, Dexcom ONE and ONE+) through Dexcom Share. If your sensor shares to the LibreLinkUp or Dexcom Follow apps, it works — no extra hardware.

How do I ask Alexa for my blood sugar?

After linking your account, say: 'Alexa, ask my glucose what is my level.' Any Echo in your home answers with your latest reading, the trend, and how fresh the reading is.

Does it work for parents and caregivers?

Yes — because it uses the same follower sharing as LibreLinkUp and Dexcom Follow, a parent or caregiver can link a loved one's sensor and ask any Alexa in the house for their number. That includes remote scenarios: a parent at home while their child is at school, or adult children following an aging parent in assisted living.

Can I check my glucose at night without waking anyone?

Yes. With Alexa's Whisper Mode, whisper your question in the dark and the Echo whispers your reading back — no phone screen lighting up the room, no waking your partner or children. Parents following a child's CGM can check overnight from their own bedroom.

Does Ask My Glucose work with Apple HomePod or Siri?

HomePod and Siri support is coming soon via Siri Shortcuts, using the same account on HomePod, iPhone, and Apple Watch. Alexa support ships first.

Dexcom + Alexa: step-by-step setup

Q: Is Ask My Glucose a medical device?

No. Ask My Glucose is an informational convenience only, never a basis for treatment decisions. Always confirm on your reader or receiver. Readings may be delayed or unavailable.

Dexcom uses two sides too: Share (the wearer turns it on) and Follow (the account that watches). Ask My Glucose signs in with the Follow account.

Share vs. Follow

In the Dexcom G6/G7 app the wearer turns on Share and invites followers. Each follower uses the Dexcom Follow app with their own Dexcom account. Ask My Glucose logs in with that Follow account — not the wearer’s primary Dexcom login.

The full setup

Turn on Dexcom Share

In the Dexcom G6/G7 app, open the sharing/Connections area and turn Share on.

Invite a follower

Add a follower by name and email and send the invitation.

Set up the Follow account

In the Dexcom Follow app, sign in (or create the Dexcom account tied to the invited email) and accept, until you see the live reading.

Start your trial and enter the Dexcom Follow account email and password.

Frequently asked questions

Yes — set up a Follow account for yourself and use it with Ask My Glucose.

Does the sensor need to be active?

Yes — Share only sends data while a sensor session is running and Share is on with an accepted follower.
