Let me not recommend stello! I tried a month of it. It is a non-prescription one since I am not diabetic, just curious. Sooo soo inaccurate and stopped 3 days before it should. Their app is crap as well! The walking is one of the best things you can do pretty much! Especially if you are insulin resistant. Since muscle doesn't need the glut4 channels that insulin brings to the cell membranes to bring in the glucose! Great for bringing it down and therefore bringing your insulin down. Sorry to bombard you with blabberings 😃
