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.

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.

Good news: both work. The difference is only in how each sensor shares its data — once connected, the Alexa experience is identical.

What is the same

With either sensor you ask the same questions (‘what is my level,’ ‘daily summary,’ ‘which sensor’), get the same spoken reading-plus-trend, see the same dashboard, and can use the same family and voice-link features.

How they connect

The only real difference is the sharing app you link:

FreeStyle Libre — connect a LibreLinkUp follower account (Libre 2, 3, 3 Plus)
Dexcom — connect a Dexcom Follow account with Share turned on (G6, G7)

Which should you pick?

If you already wear one, keep it — Ask My Glucose supports both equally. If you have both, you can link them and simply ask which sensor is currently reporting.

Frequently asked questions

Can I use both at once?

Yes — link both and ask ‘which sensor am I using’ to hear which is currently active.

Is one faster on Alexa?

Speed depends on each maker’s sharing service, not on Ask My Glucose. Every answer tells you the reading’s age either way.
