See your Blood Glucose Levels on your Windows PCConnects directly to Dexcom G7 and FreeStyle Libre, plus Dexcom G6 and other sensors via Nightscout

Install Glucose Widget free from the Microsoft Store, sign in with your Dexcom account, and your live Dexcom G7 reading appears in an always-on-top widget on your Windows desktop. There’s no official Dexcom desktop app for live readings, so this is the simplest way to see your glucose on a PC.

Abbott doesn’t make a live glucose app for Windows — LibreView is a website for reports, not your real-time number. Glucose Widget is an independent Windows desktop app that shows your live FreeStyle Libre 2, 2 Plus, 3 or 3 Plus reading and trend arrow in an always-on-top widget on your PC, using Abbott’s LibreLinkUp follower service. Install it free from the Microsoft Store.

Create a free LibreLinkUp account and have the wearer invite you from their Libre phone app (Connected Apps → LibreLinkUp), then accept the invitation in the LibreLinkUp app. Install Glucose Widget free from the Microsoft Store, choose FreeStyle Libre via LibreLinkUp as the data source in Settings, and enter your LibreLinkUp email and password. Your live reading appears in an always-on-top widget on your Windows desktop.

Sign in with your primary Dexcom account — the one the sensor is set up under (the phone running the Dexcom G7 app). Don’t use a follower account; follower logins can’t pull readings. Dexcom’s Share service only releases data when that account has Share turned on with at least one follower added. Following your own glucose? Add any follower in the Dexcom app (e.g. a family member) to switch sharing on. A parent following your child? Enter your child’s Dexcom login.

Glucose Widget connects directly to Dexcom G7, using the same account you use in the Dexcom app, and to FreeStyle Libre 2, 2 Plus, 3 and 3 Plus through LibreLinkUp. No extra software is needed for either. If you wear a Dexcom G6 or another CGM, you can connect through Nightscout instead.

FreeStyle Libre — yes, directly. Libre 2, 2 Plus, 3 and 3 Plus connect through LibreLinkUp, Abbott’s free follower app. The wearer invites you from their Libre phone app; then in Settings choose LibreLinkUp as the data source and enter your LibreLinkUp email and password. Libre sensors paired with an insulin pump, or used only with a Libre reader, can’t share to LibreLinkUp, so they aren’t supported directly.

Dexcom G6 and other CGMs — yes, through Nightscout. Nightscout is a free, open-source project that collects your CGM readings into a website you control. If your readings already flow into a Nightscout site, Glucose Widget can display them. You do need your own Nightscout site already up and running — we don’t host one for you.

Open Settings and set Data source to Nightscout. Two fields do the work:

Username — your Nightscout site address, for example https://yourname.up.railway.app
Password — your Nightscout access token

Many Nightscout sites allow read-only access without a token. If yours does, leave the Password blank. Set Display Units to match your site (mmol/L or mg/dL), then save.

In Advanced mode each of the three sensors can use a different source, so you can mix a Dexcom account, a LibreLinkUp account and a Nightscout site in the same widget.

Yes — it works worldwide with both Dexcom and FreeStyle Libre. For Dexcom, the widget supports both of Dexcom’s Share endpoints, US and International, and connects to whichever matches the region your Dexcom account was created in. For Libre, LibreLinkUp finds your account’s region automatically.

People are already using Glucose Widget in Australia and New Zealand, the United States and Canada, the UK and Ireland, across Europe — including Germany, Italy, Sweden, Poland and Czechia — and in South America.

In Settings, set Region to “United States” or “Outside US (International)” to match your Dexcom account, and choose mmol/L or mg/dL so readings appear the way your country reports them.

If you connect through LibreLinkUp or Nightscout, the Region setting doesn’t apply — Nightscout reads from your own site wherever it’s hosted.

No. Readings flow directly from Dexcom’s or Abbott’s LibreLinkUp servers (or your own Nightscout site) to your PC — we don’t touch them. Your sign-in details are encrypted with Windows DPAPI and stored locally on your machine, not on our servers.

No. It’s a tiny WPF app that idles almost entirely, waking only to fetch a reading every few minutes. You won’t notice it on battery.

Each US$5/year subscription covers one device. If you want it on two PCs (laptop + desktop, for example) just take a second subscription — still US$5 per year each.

Windows 10 or Windows 11. The app is built on .NET 8 (WPF) and installs straight from the Microsoft Store as a signed, verified app — everything it needs is bundled, so there’s nothing else to download.

The widget keeps showing your last known reading, greys the numbers and pulses the border amber so you know it is not current. Licences revalidate once a week, and you can stay offline for up to 28 days before the app locks, so brief outages are a non-issue.

If it doesn’t work for you, email us within 14 days of your first payment and we’ll refund the full amount — no questions. Cancel anytime from your billing portal to stop future renewals.
