Please don't delete reviews! The recent update has fixed NOTHING! There's NO way to change the volume or change it to a tone of your choosing. And the arm scan is NOT in real-time. When I compare a finger stick to the arm scan, it's ALWAYS almost 20+ pts off. This should NEVER be our only means to keep track of glucose. If we rely on this method, we can potentially be in big trouble! The volume of alarms can potentially harm our hearing while wearing a Bluetooth! This app needs a warning label!!
