Frequently
asked questions

What is Glynce?

Glynce is an all-in-one diabetes app that brings together CGM readings, food logging, Apple Watch support, daily goals, and glucose insights in one beautifully simple dashboard. It works with all the major continuous glucose monitors, so your glucose readings land in one place.

Which CGMs does Glynce support?

Glynce works with:

  • Dexcom
  • FreeStyle Libre
  • Abbott Lingo
  • Eversense
  • Medtronic
  • Medtrum
  • Nightscout
  • Apple Health

Your glucose readings sync automatically once connected, and you can also log readings by hand.

Can I use Glynce without a CGM?

Yes. Add glucose readings by hand, or let Glynce pick them up from Apple Health if a meter or another app writes them there. Food logging, daily goals, and insights work either way, so you can start without a continuous glucose monitor and connect one later.

How does food logging work?

Scan a barcode, snap a photo, describe your meal in a few words, or search the food library, and Glynce fills in the nutrition for you. Every meal lands on your glucose chart, so you can see the glucose response it caused instead of guessing.

Can I see my glucose without opening the app?

Yes. Your glucose readings show up on:

  • Home Screen and Lock Screen widgets
  • Apple Watch app and complications
  • Live Activities and the Dynamic Island
  • The CarPlay dashboard
Does Glynce work with Apple Health?

Yes, in both directions. Glynce reads glucose from Apple Health, along with your steps, activity, and sleep, so your trends line up with the rest of your day. Once you grant access it writes your glucose readings, meals, and water back to Apple Health as well.

How is my health data handled?

Your glucose readings are processed on your device, not on our servers. Glynce is operated from the Netherlands and follows the GDPR. See our Privacy Policy for the full picture.

Is Glynce a medical device?

No. Glynce is for information only and does not provide medical advice, diagnosis, or treatment. Always confirm readings with your CGM's official app and follow the guidance of your diabetes care team.
