My blood glucose monitor is older and not capable of linking to this app or any other. So, I enter my own readings (it's very easy). The app links to newer monitors so entry is automatic. Glucose readings are automatically (and instantly) recorded on a graph comparing my reading against high and low goals. Helps me stay on target. I can record notes on each individual reading to remind me of what I did to cause a reading to be too high. If you're diabetic or prediabetic get this app now!

Nice app but could be improved by providing toggle switch on home screen to change units quickly instead of having to navigate to settings every time. This is because I have to enter readings in mg/DL but want see results quickly in mmol. Also it only shows one reading per day in the graph even if you enter multiple readings. Upgrading to 5* as great Comms by developers and willingness to improve app.

Thanks for the detailed feedback! We plan to add the option to change units directly in the reading details in the next update. You can already view all readings on the graph by disabling aggregation in the chart settings. For more info, please contact our support team at Support@medm.com. Best regards, MedM Team

Average. Not as comprehensive as OneTouch app. Some settings a pain to use. Lots of room for improving the UI.
