See your Blood Glucose Levels on your Windows PCSupports Dexcom G7 directly, plus Libre, 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.

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.

No. A Dexcom G7 is the simplest option — the widget connects straight to Dexcom using the same account you use in the Dexcom app. If you wear a FreeStyle Libre, a Dexcom G6 or another CGM, you can connect through Nightscout instead.

Yes — through Nightscout. Nightscout is a free, open-source project that collects your CGM readings into a website you control, and it supports FreeStyle Libre, Dexcom G6 and many other sensors. 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, and the widget can’t read a Libre or G6 sensor directly.

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 and a Nightscout site in the same widget.

Yes — it works worldwide. 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.

People are already using Glucose Widget in Australia and New Zealand, across Europe — including Ireland, Italy, Romania and Czechia — in the United States, 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 Nightscout rather than Dexcom, region doesn’t apply at all — the widget simply reads from your own site, wherever it’s hosted.

No. Readings flow directly from Dexcom’s servers to your PC — we don’t touch them. Your Dexcom credentials 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.
