Question

Can I check my GMI on my guardian 3

Response from developer

Hello! Please give our Technical Support team a call for more information at 1-800-646-4633, option #1. Thank you.

Horrible annoying app

First, the alert sounds can be helpful and obtrusive. It will interrupt music videos and everything else when it makes a noise. Sometimes making them stop all the together. When you get an alert and you go to the app to check what the alert might be, it sounds the alert again right in your face. Also, every time I insert a new sensor. I have to delete the app and reinstall the app and go through all the set up. Every time I put on a new sensor. New updates are rarely available. Every time only seemingly to make the app worse and worse.

A Worsening

This new version cannot be considered an improvement.

1. It does not work if your CARELINK application is placed in a country outside the US. Therefore you cannot recover your stored data of previous months.

2. Most of devices used to measure blood glucose are graduated in milligrams per deciliter (mg/dl), but this new worsening is set to the weird seldom used graduation of millimoles per liter (mmol/l). Therefore calibration requires continuous transformation of units, something never before required.

What are these Medtronic “programmers or engineers” thinking of?

What a bluff

How much does the Guardian Connect US app cost?
