Can’t open it ### 1/5 — Used to be good, now unusable *2023-12-06, version 1.3.7* This app used to be my go to app for viewing my nightscout data, I tried to use it today after a few years away from nightscout and it’s essentially unusable. It crashes every time you load it after entering your url. Basic url, token url, it doesn’t matter, the app still instantly crashes. Hopefully it’s a short term problem, but it feels like the app might have been abandoned ### 2/5 — App crashes, can’t open *2022-10-07* I have added my server to the app but every time I tap the icon it opens then closes the app. Force closing/re-installing and rebooting phone cannot stop the app from crashing. My Nightscout server is on version 14.2.6 (latest as of Oct 7, 2022). I like the UI in your screenshots but I cannot access the app sadly. ### 1/5 — Doesn’t work at all - no longer supported? *2020-11-18, version 1.3.6* So I’ve put in my Nightscout URL, but it can’t retrieve any data from it. It seems like this app is no longer supported. It would be nice if the devs of apps like these put a disclaimer up when they’re no longer supporting them. ### 1/5 — Can’t access site *2020-11-02, version 1.3.6* Iphone ios 14 Apple watch 5 ### 1/5 — No bueno *2020-09-07* Like the others said- it doesn’t work. Try using “Nightscout” or “Nightguard.” ### 1/5 — Broken code *2020-01-20* This app is current broken and can not connect to Nightscout apps hosted on Heroku. I don’t have the ability for testing on other hosts. **Developer response:** I've recently updated the application to accommodate the latest versions of nightscout. would love your feedback if your issues have been resolved. Thanks for your patience. This is something I do in my free time and I do this for free. ### 1/5 — Garbage *2019-08-27* Doesn't connect please remove this app from the list **Developer response:** I've recently updated the application to accommodate the latest versions of nightscout. I would love your feedback if your issues have been resolved. Thanks for your patience. This is something I do in my free time and I do this for free. ### 1/5 — Completely useless *2019-08-21* Does not connect to site. Ever. Don’t waste your time. ### 1/5 — Useless *2018-07-29* Doesn’t work.. won’t load ANY Nightscout. The following error pops up for half a second but then immediately disappears: “Cannot Reach Nightscout Site A connection to was not successful. Reason: The file could not be parsed correctly. Please check the URL and try again.” All attempted URLs are correct, none of them work. ## Frequently asked questions about Nightscouter ### What is Nightscouter?
