0 stars if I could. App installs on 'phones (Fairphone 5, Oneplus Nord CE 5G, Oneplus Nord 2), allows login, demands approvals for agreements... and then refuses to run. No option to "run without testing", or that; nor does it check before you go through all the motions. What's the point of an app that runs on so few devices? Really, I'd have to try hard to write something that badly. I contacted tech support. They were no help, just "not supported" for any of my devices.

The option to set alerts to reoccur is useful. The sound that plays is loud, though sometimes a little too loud in comparison to other apps, especially through headphones. It also turns off sound for other apps which isn't ideal. We need a better history record. We also need an alarm that plays constantly, rather than once every 5 minutes. This isn't enough to wake people up, especially when low. We should have the option to set multiple alarms, more than just one high and one low alarm.

Just got my 10 day trial packed delivered and the instructions were to install this app and follow instructions. I have setup a username and password and the app doesn't recognise it. It keeps logging me out. Further I have downloaded the clarity app and the login details work perfectly fine on there. I have been using Libre before this and never had any issues with it. What a waste of time. 😔
