It’s very easy to use Sognos. My wife and I decided to try it out because we wanted to learn more about the impact of different foods on our glucose levels. We signed up for 6 months and we are about 2 months in. The education has been fascinating. What I like most about the app: 1) it syncs with my iPhone and Apple watch. 2) you can take a pic of your meal and it will accurately analyze the components to predict the impact on your glucose levels before you eat. 3) I have shared some charts of the impact (level of spike and the duration) of certain foods with my family — eg McDonalds 2 cheeseburger meal with a coke. For me, understanding this impact makes me not want to eat this type of food as much. 4) the device and patch covers are very easy to use and showing, workouts etc are no issue 4) since we started using Signos l, we have lost about 15 lbs. Highly recommend!
