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.

FreeStyle Libre + 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.

The one thing people get wrong is which login to use. This walkthrough keeps it simple: there are two apps, and Ask My Glucose uses the follower one.

Two apps, one rule

LibreLink is the wearer’s app (it shows their own sensor). LibreLinkUp is the follower app (it watches someone’s readings). Ask My Glucose always signs in as a follower — so the login you enter is the LibreLinkUp one, never the wearer’s LibreLink login.

The full setup

In LibreLink (wearer’s phone): invite a follower

Open the menu, go to Connected Apps, choose LibreLinkUp, and Add Connection. Enter the follower’s name and email, then send the invitation.

In LibreLinkUp (follower’s phone): accept

Install LibreLinkUp, create an account with that same invited email, and accept the invitation. You should see the live reading.

Link it at askmyglucose.com

Start your free trial and enter the LibreLinkUp email and password. That follower login is what connects your sensor.

Pair your Echo

Tap Pair an Echo for a 6-digit code and say ‘Alexa, ask my glucose to pair with code 1 2 3 4 5 6.’

Test it

Say ‘Alexa, ask my glucose what is my level.’

Hear your glucose out loud today

Works with FreeStyle Libre 2/3/3+ and Dexcom G6/G7. 14-day free trial, then $4.99/mo (family $9.99/mo).

Frequently asked questions

The wearer and the follower can be the same person, right?

Yes. Many people invite themselves — they install LibreLinkUp with a second email and use that follower account with Ask My Glucose.

I entered my LibreLink login and it failed — why?

Because linking needs the LibreLinkUp (follower) login. Enter the follower account’s email and password instead.
