Shocked no one has rwote an review on this app. I just got done 14 day and it was to be free but cost 38 dollars after my insurance got done with it. 1. Cant send results via email. Your doctor has to have a librelink ID. 2. You cant trust the readings to give youself insulin you have to finger prick test yourself anyways. Results off more then 100. Over all this probuct is a good Idea but not worth it if you cant trust it. You see what i mean when you try it yourself.
