[Open Source] I built a free Wear OS watch complication, tile & phone widget app for SinoCare LinX and Dexcom ONE+ (CGM Glance) — looking for feedback & testers!

Type 1 & LADA

Hi everyone! I built a free, ad-free, open-source Android & Wear OS companion app called CGM Glance for users of SinoCare LinX and Dexcom ONE+ sensors who want to see their glucose readings directly on any Wear OS smartwatch face (Samsung Galaxy Watch 4/5/6/7/8, Pixel Watch, Xiaomi Watch 2, etc.) and on phone home screen widgets.

Screenshots, interactive setup guide, and install links:

Key features:

  • Works on ANY Watch Face: Provides a standard Wear OS Complication (Short Text, Long Text, Ranged Value) plus a dedicated swipeable Watch Tile with range-colored readings (70-180 mg/dL), calculated trend arrows, and reading age.
  • Resizable Phone Widgets: Supports SinoCare LinX and Dexcom ONE+ on your phone home screen.
  • Optional local Health Connect integration.
  • 100% Private & Local: The app doesn’t even request the Android INTERNET permission. No cloud accounts, no servers, no ads, no analytics — it simply reads your official CGM app’s ongoing notification locally on your phone.

How to install it for free from Google Play (in 2 quick steps):

Step 1 — Join the Google Group to unlock tester access (click “Join group” using your Google Play account):

Step 2 — Opt-in and download officially from Google Play (for both phone and watch):

(Google requires 12 testers for 14 days on new personal developer accounts before unlocking public search in the Play Store. Everyone who installs the app now keeps it permanently and receives all future updates automatically via Google Play!)

GitHub repository (GPL-3.0): GitHub - smakeru/CgmGlance: Shows your CGM glucose on any Wear OS watch face, as a standard complication and tile. Optionally writes readings to Health Connect, where Samsung Health reads them from. Extends the official app, never replaces it. Not a medical device: no alarms, no treatment decisions. · GitHub

Thanks so much, and I’d love to hear your real-world feedback or feature suggestions!
