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.

Great App, Wish I Could Switch to It.

Was able to setup and configure Nightscout using the walk thru.Like the app a lot. Looks like a great group of folks have contributed to this project.I can't understand why alerts are not able to sound when the phone is locked. This limits the usability of the app greatly during the day. I'm sure this has been addressed. Must be a good reason.Also my data is delayed 2-3 minutes from the Dexcom follow data. Sugarmate populates as quickly as Dexcom. The way data is routed to the Nightscout site must cause the delay. I can live with 2 min. delay but kind of a bummer.If the alerts were always active / able to be received by notifications (no matter what my phone's screen is doing), this would be awesome.As it is, I got to stick with the Dexcom Follow app (terrible and annoying alerts I can't adjust) and Dexcom's increasingly poor and disconnected support. Is there any chance of making this app more usable--beyond sitting on my nightstand with the screen dimmed. Or just a handy way to tap into the Nightscout website if I'm curious? We mainly use the follow app as a way to monitor our son's glucose in realtime, wherever we have Wi-Fi / cell data. He might be outside playing or in his room on the other side of the house. The bluetooth limitations (maybe 20ft.) of the receiver make it impractical to be our primary source of alerting us. So we need our phones to act like his receiver basically with the alarms.Appreciate what yall are doing with this app!

Hi! Thanks for your feedback. To have alarms working as if the app was running in foregroundis prevented by apple because of battery reasons.You could discuss this in more detail here:https://github.com/nightscout/nightguard/issuesI would expect that the Dexcom app only sends push notifications and isn‘t able to continuously play sounds in case of an alarm, too.You could increase the rate of backgrounds alarms with nightguard when wearing an apple watch. But it will always be delayed up to maybe 15 minutes. You could get faster push notifications when configuring the pushover service on your nightscout backend.Cu!

App works good, would like more readable watch complications

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.

Hi Kyle! Thanks for your feedback. What watchface are you using? There are a lot of different faces with a lot more different complications and I‘m already supporting a lot of them. But maybe you have something that should be supported as well.The complications have very much predefined ways of what and how can be displayed. So I‘m very mich restricted to it.

Working well for 2 days on iPhone then reading won’t change, its showing reading -1200 min. Gluroo is working fine. Turned the phone on and off, uninstalled the app 3 times still showing the same reading. Can anyone help?Updated: Thank you for the response. I have waited 20+ hours until the countdown minutes reached 0 then my Apple Watch gave the same readings as Gluroo but on my iPhone the readings wouldn’t change, still counting +1, +2, +3, … minutes for a while (30+ minutes ) then everything seems to reset. Now everything matches and working great. Thank you. (FYI: Could the problem come from forwarding the time on my iPhone? I have forwarded it for 24 hours and then changed back to automatic for a few times to do something before this problem occurs)

You can open an issue here:https://github.com/nightscout/nightguard/issuesThere have been quite some issues with gluroo here, so use the search. If nothing helps, you can send me a read only URL togluroo.hermanns@spamgourmet.comShould be easy to track down then. I would expect that your security token is invalid.Update:Interesting, yes, would expect that different times on watch and phone could have side effects. But didn’t tried this myself so far.

It does some nice visualization with the data that is very helpful. It was better when the watch app worked. It quit working for me with the last update.It was updated and the complication started working again. This is such a great app, thanks for all your hard work!

Try V3.9.1. This should improve updates on the watch.

Try V3.9.1. This should improve updates on the watch.

Nightguard has its 10th anniversary! I was asks how you can support the app development: Now you can subscribe to the PRO and MAX version of Nightguard. But you don't have to. Nightguard will always be free, open-source and advertising free. To give something back to subscribers, some new features will be implemented in return. Right now, this is in Pro Abo: - Push Notifications for critical ranges for CAGE, BAGE, SAGE and Reservoir - Support for the Dynamic Isle and Live Activities - CarPlay Support - Statistics are available directly on the watch and new Max Feature: - all Pro Features - Drastically improved Live Activity Updates and Updates of the Dynamic Isle 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. This Backend sends thousands of Push Notifications a Month for every Device you are using. This dramatically improves the update frequency of the Live Activity and the Dynamic Isle. This Feature has been requested as long as I'm developing the app and was quite hard to develop, because of the Apple Push Notification Server that needs to be maintained. Hope you enjoy it. 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. Looks like Apple allows only one update a day without the widget. When using the widget, looks like you can get 1-2 updates an hour. V4.0.4: - #350: Improved BedsideView with even bigger bgvalues. 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!)
