Features & Capabilities

Nightguard is a Chrome extension that displays your Nightscout BG values from the backend and alerts you when readings go out of range. It shows an overlay chart of yesterday's values to hint at future trends and lets you snooze or reactivate alerts as needed.

User Reviews

Nightguard is praised for real-time glucose readings on Apple Watch and a clear iPhone interface, with cross-device usefulness. However, reviewers repeatedly report Apple Health sync problems, unreliable alarms, watch app instability after updates, readability issues on small screens, and limited graph data. The app offers strong wrist access but reliability and UI clarity require attention.

Pros

Strong Apple Watch support with real-time glucose readings on the watch and functional watch complications.
Clear, quick-updating data presentation on iPhone.
Works across multiple devices and data sources, offering flexibility in how glucose data is viewed.
Active improvements and fixes to watch features (e.g., watch complications) by the developers.

Cons

Unreliable Apple Health sync; often requires being in the Glucose section and may only sync recent hours.
Notifications/alarms not reliably triggering or audible; alerts may fail if the app is not open.
Watch app instability and complications can break after updates or OS changes.
Readability/UI issues on small screens (tiny text on watch complications) and limited graph data.
Inconsistent update intervals for watch complications and widgets.

Recent reviews

The app itself works quite well. My only complaint is that the watch complications are far too small to read. For the smaller one I can see the color but it’s impossible to read the value. And for the larger complication, it would be great if thefe was an option to just see the latest value in a much larger font rather than the latest 3 readings in tiny writing that is too difficult to read.

Love the watch readings!

Whenever I try to adjust the alert settings for a high blood sugar and low blood sugar no matter what I set it to it automatically defaults to 180 for a high and 80 low. I have uninstalled and reinstalled the app and I still get the same results.
