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.

This works, but the app is bare bones with a lack of features. Alerts, for example, aren't that controlled. There isn't really a point receiving an alert if I go above for one reading and then below for the next. The app also pauses other applications when you get an alert, which is nice for the first one but a pain for all the following ones. I have also noticed multiple times that the app has failed to notify me about my numbers. This has happened multiple times and is not safe.

The app is constantly crashing or loosing signal even if I always keep the phone with me. The saddest thing is that you need to log-in again after the crash and set up everything from the beginning. Which is not possible as you don't remember transmitter code. You need to remove it from the body, which means that you loose 10 day session (maybe less days, but still...) and the money paid for it. Also it crashed after the time change, which means that it will be happening at least 2 times a year.
