ReceptionRating · Positive reviews · Number of ratings

Glucose tracker++ holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Glucose tracker++ has 1.5K ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 34% of Glucose tracker++'s written reviews are positive against 55% of Carb Unit Diary for Diabetics's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Glucose tracker++ ships an update every 7 months, Carb Unit Diary for Diabetics every 3 weeks. Both last shipped on October 26, 2026.
