Beacon gives you an update every time duration you choose from every 1-30 minutes to know if your blood sugar is trending up, down, or holding steady. There’s also an option for it to say your exact glucose number instead of just having it play a tone. It’s super easy to use and a great way to stay on top of my glucose trends before I get too high or too low, especially when I’m distracted doing things like working, reading, on the computer, working out, or playing video games. I can set the volume low enough so that only I can hear it and others around me don’t even notice. I work in healthcare and would highly recommend this app!
