가디언센서 교체시

가디언 센서 교체시 새 센서 수치나오기까지 남은 시간이 나왔었는데 앱이 업데이트 되면서 사라졌어요 ㅜㅜ 다시 나올수 있게 해주세요

Will not stay logged in

For a month I have been unable to keep it updating. This app is very irritating. I have followed many suggestions but to no avail. I want to cancel this garbage and get it off of my phone. I hope this is not setup for endless subscription as I can’t find that info with a renewal date coming soon.

10minutes

◽️更新が10minutesになります。5minutesが正しいのに、5minutesで更新しません。さらにNOWが出て来なくなりました。


The update time is set to 10 minutes. It should be 5 minutes, but it doesn't update in 5 minutes. Furthermore, the "NOW" button no longer appears.

◽️頻繁にログアウトする。放置でモニタリングが出来ない。勝手にログアウトしてしまったらアラートも意味がなく有料の意味が無い。

I log out frequently. I can't monitor it if I leave it unattended. If I log out automatically, alerts are useless and the paid service is pointless.

◽️上記の不具合がなければ優秀なアプリです!

If it weren't for the above issues, it would be an excellent app!

医療用なので、今直ぐにでも改善して欲しいです。子供の血糖値をモニタリングするために使っています。

Since this is a medical device, I would like it to be improved immediately. I use it to monitor my child's blood sugar levels.

Great app — request for daily (calendar-based) average

I really appreciate this app — it has been extremely helpful for managing daily glucose data. Thank you for continuously improving it.

I would like to request one additional feature regarding the average glucose display. Currently, the average is calculated over the past 24 hours from the current time. While this is useful, it would be even more convenient if there were an option to calculate and display the average based on a fixed daily period (e.g., from 00:00 to 23:59).

Although it is possible to manually adjust the time range, doing this every time is a bit cumbersome. Having a simple toggle or preset for “daily average (calendar day)” would make it much easier to review trends and compare days.

Thank you for considering this feature, and again, thank you for your great work.

Life saver

I’m not very good at tracking my glucose. So discovering this app has changed my life. My glucose now displays on my Apple CarPlay, Sugar Pixel, Apple Watch, Garmin Edge, and lock screen. The developer is agile and responds immediately to any new issues.
