GlucoseWatch: Your Blood Sugar Values – Always on Your Wrist. With GlucoseWatch, you can view your glucose values quickly and discreetly on your Apple Watch. Designed specifically for Apple Watch, the app retrieves readings from your LibreLinkUp account and presents them at a glance. Your values at a glance: See your current glucose value and trend directly in the app. For a quick overview, you can also add a complication to your watch face. Complications do not update continuously. Open the app or tap the complication to retrieve the latest reading. Optional Apple Health integration: If you choose, you can sync your glucose values with Apple Health and view them alongside your other health data. Privacy comes first. Your glucose readings are not stored on our servers. Your LibreLinkUp credentials are stored in the Apple Watch Keychain and can be entered directly on your Watch. (For easier setup, you can optionally use QR login: your browser encrypts the credentials for your Watch before an encrypted package is stored briefly on our transfer server. Glucose readings are not sent through this server.) Important note: GlucoseWatch is intended to display glucose readings and does not replace medical advice or treatment. Always consult a medical professional about health-related questions. For more information and legal notices, visit glucosewatch.chadly.de. Questions or issues? Contact us at glucosewatch@chadly.de.

Verdict
The clearest difference is price: GlucoWatch at Free against GlucoseWatch's $3.99. GlucoWatch also leads on rating (3.6 vs 2.5) and ratings volume (206 vs 2). GlucoseWatch's advantage is in-app purchases (none vs 4). On update cadence, ads and device support there is nothing between them.
