Set up Nightscout in Glynce

Updated September 14, 2026

Setting up Nightscout in Glynce means giving Glynce the address of your own Nightscout site and, optionally, your API Secret. Glynce then reads your glucose from there. This page covers the in-app connection, not how to host or run Nightscout itself.

What you need

• A running Nightscout site with an https:// URL.
• Optionally the API Secret, if your site requires authentication.
• An uploader (or another source) that delivers readings to Nightscout.

Steps in Glynce

1. Have your Nightscout URL ready (for example https://nightscout.example.com).
2. Open Glynce, go to your profile, then Data Sources.
3. Choose Nightscout.
4. Enter the site URL. Add the API Secret only if your Nightscout site needs it.
5. Test or save the connection and wait a moment for readings to sync.

URL tips

• Use https://, not http.
• A trailing slash is optional; Glynce strips it on save.
• The site must be reachable from your iPhone.

If readings do not arrive

• Check that your Nightscout site opens in a browser.
• Check that your uploader is running and writing fresh values.
• If the site requires auth: re-check the API Secret (no spaces).
• In Glynce under Data Sources, test or re-save the Nightscout connection.

Nightscout is community software you host yourself. Glynce reads from it; data quality and timing depend on your setup. Glynce is not a medical device or clinical tool. The API Secret stays on your iPhone (Keychain, including the shared Keychain used by widgets). Glynce does not upload it to Glynce servers. Readings can be delayed. Glynce is for viewing patterns, not a replacement for the alerts you already rely on (official CGM/pump app or your existing Nightscout alarm setup). Don’t paste your API Secret into email or chat with support. Help: support@glynce.app.
