Downside is the alarms don’t function unless the app is active ie open displaying data. Wish the alerts worked with locked screen or when utilising other apps etc ### 3/5 — Großer Fan, aber *2026-07-12* langsam wird es unschön. Ich freu mich riesig, dass sich in der App seit einigen Monaten so viel tut. Ich bezahle pro für „Dynamic Island“ und „Live activities“ und surprise: nutzlos. Aktualisiert sich alle paar Stunden. Nicht mal wenn ich die App öffne aktualisiert es sich jedes Mal. Ich bezahl jetzt nicht 50€ für Max, nur das es damit eventuell besser tut. Bietet wenigstens einen testzeitraum an. Und der nervigste Bug seit Jahren ist immer noch drin: öffne ich die App nach längerer Zeit kommt sofort ein Alarm bzgl. fehlender Werte. Obwohl ich es schon entsprechend eingestellt hab. Und es beendet die Audio Wiedergabe. Und ja, ich weiß der bug ist bekannt im git. Aber es tut sich nichts mehr. Die fixe dazu waren nicht erfolgreich. **Developer response:** Danke für das Feedback! Wie sich herausstellte ist ein Update der Dynamic Isle sowie der Live Activities nur per Push Notifications technisch möglich :(. Dies ist von Apple so festgelegt worden. D.h. bei einem Update alle 5 Minuten sind tausende Push Notifications pro Gerät und Monat notwenig. Dazu muss die Server Hardware angemietet und die einzelnen Push über einen speziellen Google Dienst per Kosten von 3,99€ pro Monat weiter gereicht werden. Sorry dafür! Hatte auch überlegt das Feature komplett von Pro zu Max zu schieben, aber dann wären vermutlich auch Nutzer beleidigt gewesen. So sieht man den letzten Wert aus der App wenigstens noch in der Isle. Der Alarm wird von der App sofort unterdrückt und kann komplett unterbunden werden, wenn man einen ansteigenden Alarmton wählt. Da das Projekt weiterhin Open Source entwickelt und frei zur Verfügung gestellt wird ist ein Pull-Request jederzeit willkommen. Leider konnte ich das auch nach verschiedenen Ansätzen nach der Umstellung auf Swift UI nicht besser hinbekommen. Ich schaue aber auch weiterhin, ob ich noch selber eine Idee dazu habe. Leider alles nur innerhalb meiner begrenzten Freizeit. Ein Support der App durch die Nightscout Community ist aktuell leider sehr stark zurück gegangen. ### 4/5 — App works good, would like more readable watch complications *2026-06-25, version 4.1.0* 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. ### 4/5 — Tolle App *2026-05-28* Die App ist toll und macht einen übersichtlichen und soliden Eindruck. Die Pro Version habe ich mir vor allem wegen der Werte im Dynamic Island geleistet. Leider aktualisiert sich dieser Wert erst wenn ich die Nightguard App selbst öffne… Da nützt mir diese Funktion natürlich nichts. Wenn das ginge, gibt’s 5 Sterne ***** **Developer response:** Danke für das Feedback. Die Updates sind in jedem Fall deutlich seltener, als wenn die App im Vordergrund ist. Ich prüfe aber nochmal, ob man das noch besser hinbekommt. ### 3/5 — Missing Medtronic pump reservoir units and IAGE *2026-03-23* Can be improved adding reservoir U remaining and IAGE. **Developer response:** Thanks for the feedback. U Remaining ist displayed in the upper right of the Main Screen. Insulin Age does not seem very important, since the remaining U should do the job, right? ### 4/5 — Unable to Set Custom Date/Time for Cannula and Sensor Changes *2026-02-20* After the latest update, I can no longer set a custom date and time for cannula or sensor changes. Even if I tap the time and select a different date/time, when I press “Save” it automatically changes to the current date and time. This makes it impossible to enter the actual change time if I forgot to record it immediately. Could you please look into this issue? **Developer response:** Thanks for the feedback. I will fix this with the next release. Update: It is fixed with 4.0.1 and you can already get the TestFlight and test this: https://testflight.apple.com/join/zE4CfcRn ### 3/5 — Problem with alerts *2025-10-27, version 3.10.0* 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. ### 2/5 — Needs better integration with Apple Health *2025-08-29, version 3.9.5* The only reason I’m using this app is to sync my FreeStyle Libre glucose readings into the Apple Health app. While it was working better earlier, it isn’t working so well now. For readings to sync, I have to be in the Glucose portion of Apple Health (AH). If I’m anywhere else, it doesn’t sync. If AH is closed it doesn’t sync. It did before. It gets its readings from Gluroo. I tried NightScout Pro with no success. When it does sync it only syncs the last 6 hours. Which means I constantly have to be opening and monitoring the AH app for glucose. The support option is confusing and requires a separate account. ### 3/5 — Apple watch *2025-08-13, version 3.9.5* After installing the app on my apple watch, I only get the readings on my watch for about an hour and it quits working. I uninstall and reinstalled numerous times. I gave up! It does work on my phone ok. ### 3/5 — Almost perfect *2025-05-10, version 3.9.3* I’m using this app every night to well.. guard me. I love it, please just add some spacing around the icon because it messes up the Home Screen harmony. Everything else is perfect! UPDATE: The “keep screen awake” feature has stopped working, which disrupts the app’s core functionality. Please address this issue as soon as possible. ### 2/5 — Nice idea, dicey execution *2025-05-01* Initially downloaded this app to get my glucose levels on my Apple Watch. Found a better solution for this. But I like that it can feed my info into Apple Health. However. It’s intermittent. I’d like it to just pick up the values from Gluroo (or LibreLink directly) and post them to Apple Health. No intervention. But that’s not the case. I lost over two days of values, More importantly, this app could use some support. Poking around in GitHub isn’t cutting it. And not resolving any issues. If I have to pay for NightScout, I will. Because it’s important to me to get that info into Apple Health. But I’m not paying for anything that doesn’t have real support. **Developer response:** Hi! Nightguard is free of charge and completely community driven. So any help is appreciated to fix the health upload. ### 3/5 — Nice to be able to get readings on watch but text is way too tiny *2025-04-03, version 3.9.3* While it’s nice to be able to get the readings on the watch, the text is way too tiny. The circle complication options are unreadable and for the large rectangle in the middle, Instead of showing three lines of tiny text, it would be great to have the option of a single current reading in giant readable text. I want to be able to glance at my watch to see my reading but I have to squint to try to even read the text. ### 4/5 — Trouble *2025-03-04, version 3.9.3* I’ve changed my nightscout URL. I have only API SECRET bur not token. App doesn’t accept new URL. Is there anything to do? ### 3/5 — Alarms don’t work. *2025-02-20, version 3.9.3* The alarms only work if the Nightguard screen is up. If you are doing anything else or don’t leave the screen active the alarms won’t push through. This is pretty basic. It’s an alarm. It needs to be active no matter what screen is up. ### 3/5 — Newest update?? *2025-02-18, version 3.9.3* After updating I no longer have the option to update via my watch face.. how can I update??? Also now I have a new watch and my screen is blank - there’s no values or anything.. please help! ### 4/5 — Port? *2025-02-07* How can i set port in the nightscout url?? ### 2/5 — Newest update?? *2025-01-28* After updating I no longer have the option to update via my watch face.. how can I update??? ### 4/5 — Wish Graph Was Useful *2024-12-15* Not possible to view certain time frames or data points on the graph. It’s just for visuals. Otherwise love it but please let us see what values are on the graph when choosing a point. ### 2/5 — Complication issues *2024-12-05, version 3.9.2* The complication with WatchOS 10 no longer appears to auto update. When clicking on the complication, the latest BG readings are shown, but on returning to the watch face, a stale reading is shown. This is a fairly critical issue for people with T1 diabetes. When using the complication as a gauge, no idea what the gauge represents when units set to mmol/L, certainly not a valid range. The stats page doesn’t show the correct number of background updates, almost all zeroes. ### 3/5 — Can’t Figure out Missed Readings *2024-12-02, version 3.9.2* I’m not sure what I’m doing wrong but Nightguard is only picking up about half of my Dexcom readings despite Nightscout and Dexcom both working continuously. Today so far with all apps open and active all day, only 76/150 readings shown. This doesn’t help me see my correct percentage in range for the day (one primary reason I prefer this to my DIY Loop screen). I wish I could figure out what the issue is. ## Most critical reviews (10 lowest-rated) ### 1/5 — PLEASE FIX *2026-05-06, version 4.1.0* After the most recent update my app no longer properly fetches data from Gluroo and doesn’t update as it used to! I have to close the app and reopen it for it to show my current BG data - this is not helpful at all!!! ### 1/5 — Alarms never go off *2025-07-29, version 3.9.4* I have tried everything to get the notifications to go off on my iPhone and nothing ever plays. I only get a simple instagram sounding chime for “missed readings”, no alerts. This is really frustrating as I have to wake up my relative during the night and I can’t hear a single alarm. ### 1/5 — Do not get *2024-10-14, version 3.9.2* Do not download my url has disappeared I can’t get it back doesn’t matter if I delete and download again now I can’t have my readings at all on my Apple Watch this is a Rubbish app that doesn’t work and the url just disappears ### 1/5 — URL Format *2024-10-02, version 3.9.2* It is saying the URL format is incorrect when I have only copied and pasted the URL. ### 1/5 — Ios 18 *2024-09-29* Dont work ### 1/5 — Stopped working *2024-09-29, version 3.9.2* Have used for several months. Would give 4/5 but have had stoppage issues several times. Have been able to correct, has not updated in over a week and can not correct it. Loved the convenience of using it with Gluroo to correct to the iWatch to have quick access to my reading. ### 1/5 — Widget does not work! *2024-08-31* After update of iphone, widget got invisible! Also widget for apple watch too. **Developer response:** Hi! Try deinstall/ reinstall the app. Then reselect the widgets. Is this doesn’t help - you can open an issue here: https://github.com/nightscout/nightguard/issues And we will drill this down together. ### 1/5 — Doesn’t work *2024-04-20, version 3.9.1* No matter what you put into this app it won’t connect. ### 1/5 — Can’t clear *2024-03-29, version 3.9.1* Can’t clear missed reading alarms ### 1/5 — Does not read glucoo url *2023-09-27, version 3.8.1* Not sure why it won’t read the url but it says it’s in the wrong format when I copy and paste ## Most praised reviews (10 highest-rated) ### 5/5 — Nacht Modus 👍 *2026-03-31* Der Nachtmodus funktioniert wieder quer mit großen Zahlen und das Problem wurde sehr schnell behoben! Vielen herzlichen Dank! **Developer response:** Hallo Frank - wie beschrieben ist die mit der kommenden V4.0.3 wieder möglich. Viel Spaß damit… ### 5/5 — Works ! *2026-02-26, version 4.0.1* Love the watch readings! ### 5/5 — Apple Watch *2025-08-20* Прекрасное приложение и очень нужное вся информация отображается!Если возможно верните поддержку старых моделей Apple watch!!! **Developer response:** Happy that you find this helpful! ### 5/5 — Please Let Us Scan Through Graph *2025-03-12, version 3.9.3* I want to be able to see my specific reading at a certain time bu pressing my finger across the graph. Then this app would be impeccable. ### 5/5 — Problem *2025-02-28* Great app, everything works great. But I changed my phone to the 15th, and my wife was the 15th plus, and notifications stopped coming! On the phone 14 Pro Max, iPad mini, and iPhone XS all notifications come!. I tried all the settings, it doesn’t work. The operating system is the last ### 5/5 — Great app, presents data in a clear way *2024-12-30, version 3.9.2* This is a great app. It presents the data on phone in a clear and quick-updating interface. If I had 2 wishes they would be: 1. A watch complication displaying the daily graph 2 consistent and configurable update intervals for watch complications and widgets…. Sometimes they update every few minutes and other times they go 25+ minutes. ### 5/5 — Every minute reading *2024-12-29, version 3.9.2* This new feature to refresh every minute is not working for me on iPhone SE and iOS 17.6. It’s still 5 minutes no matter what is the setting. ### 5/5 — Data Refresh if in background is not perfect. 5 stars for other features. *2024-12-18, version 3.9.2* New question: - is it possible to improve refresh rate for Night Mode widget? Time is counting and there is i.e. 10 minutes but value is not updated. I would keep it with always on if it will work. ### 5/5 — Awesome companion *2024-08-26, version 3.9.2* This is certainly the most awesome companion to my freestyle libre I have ever used. Full disclaimer: it does require some setup with night scout and all that. And there are some caveats with regard to widget update frequency that users have to be aware of but it‘s important to note that those are not the „fault“ of the developers. However, ones it is set up (iPhone + Watch with widgets) and the caveats are understood, this is totally awesome. It really transformed my way of „looking“ at my values. Especially during work. Having a quick glance at the display during a meeting, while working etc is incredible. I rarely open the Libre app anymore. Thanks a lot! If there were some in app option to throw money at the development team, I‘d do so in a heartbeat. ### 5/5 — Reading stuck *2024-07-17, version 3.9.1* 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) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
