^aDaily sessions refers to the number of times a Diabits user looks at the CGM values and predictions during 1 calendar day. Diabits records each user’s CGM data as long as the application is running on the smartphone even if the user is not actively looking at the results, so days with 0 sessions are included.

^bAll P values <.001 are reported as P<.001. P₀ and P_fewer are defined in the methods section of this paper.

^cGMI: glucose management indicator.

^dHBGI: high blood glucose risk index.

^eLBGI: low blood glucose risk index.
