About nightguard

Disclaimer!
Don't use this App for medical decisions. It comes with absolutely no warranty. Use it at your own risk!

You can use nightguard to submit your bg values to the Apple HealthKit. This is disabled by default but can
be enabled in the nightguard app.

Nightguard is an app that displays your blood glucose values from the Nightscout backend.

It is a native iOS App with support for the Apple Watch.
Features are:
- Define a range of acceptable blood glucose values.
- Whenever your values are out of range you will be alerted.
- You can snooze the alerts all the time and for a defined time period.
- You can reactivate the alerts all the time.
- You can activate alerts if the values are rising or falling too fast.
- The app displays yesterdays values as an overlay chart. This way you have a hint about how your values could behave in the future.
- Tune your basal rates with the statistics function to overlay different days
- Sync your bg values to HealthKit (optional)

For the alarms to work the app has to be active. So you can enable a screen lock that keeps the app running all night long.

Have a look at www.nightscout.info for more information about how to setup your own Nightscout backend.

V3 can be activated in preferences. Sorry, but looks like gluroo and nightscout pro backends have problems forwarding the Bearer Header/supporting V3 API - Improved swiping performance on the Apple Watch V4.5.0 - Optimized for iOS27 - Under certain conditions Alerts could happen during day-change at 0 o'clock. These should be (hopefully) fixed now. - Changed Nightscout API from v1 to v3 - PRO: More robust Chart Rendering on the Live Activity and the Dynamic Isle - Improved Performace V4.4.0 - Pro/Max: Better Chart in the Live Activity - Pro/Max: Better Chart when pressing on the Dynamic Isle - Pro/Max: New Chart Details when touching the chart on the Phone - Pro/Max: New Selection Mode on the Watch: Use the digital crone to get Chart Details directly on the Watch V4.3.0 - (Hopefuly) improved Alarm snoozing when opening up the app - Pro/Max: Improved Live Acitivity and Dynamic Isle with Glucose Chart of the last hour V4.2.0: - New Max Subscriptions: We are maintaining a backend for all Max Users now.

V4.1.0: - New Pro Feature: Statistics are available on the watch now, too - Improved Background Updates. But keep in mind to enable the nightguard Lockscreen Widgets.

Have fun, Frank ;) - #351: mmol alarm ranges can now be entered as floats once again - Fixed a problem with the chart rendering V4.0.3: - #347: Fixed "missing values" alarm that sometimes occurred at midnight - Fixed a crash if popups occurred in the nightscout web view - The Pro View should appear only once per new Nightguard version now - #349: Added screen rotation to the bedside view V4.0.2: - #344: Moved the popup for the action button that open the fullscreen bedside view to a better position - Fixed the low prediction label on the snooze button. Should be once more visualized now. This is back for Giovanni ;). - Carplay Support V4.0.1: - Fixed a bug resetting the cannula age and others V4.0.0: - Completely rewritten iOS App in SwiftUI - CAGE, SAGE and BAGE warning ranges (for colors), can now be defined in the AlarmView Section. - Warning and Critical Coloring of the Reservoir Insulin Units. V3.10.1: - Fixed alarm ranges. They can be once more modified now. V3.10.0: - Support for IOS 26 - Liquid Glass Look-and-Feel V3.9.5: - Improved iOS Widget with better visualization (for Ben ;) V3.9.4: - Delta Arrow should be displayed for gluroo users now - The 1-minute updates have been fixed (thx Tomasz!)
