The screen is too easy to rotate. Just turn off the auto-rotate and make the sidways view a button. Also, same deal as other people, calibrate requires me to put it in twice just to read what my finger stick says, like brute forcing it. I also can't lay on my CGM at night because it blocks the signal for some reason even though my phone is 3ft away from the transmitter on my arm. Making the alarms easier to understand wouldn't hurt, and making an "alarm on/off" on the main screen would be nice.
