# Glucose tracker++ vs Carb Unit Diary for Diabetics

The clearest difference is update cadence: Carb Unit Diary for Diabetics at every 3 weeks against Glucose tracker++'s every 7 months. Carb Unit Diary for Diabetics also leads on review sentiment (55% vs 34%). Glucose tracker++'s advantage is rating (4.5 vs 4.2) and ratings volume (1.5K vs 24).

Both are free to download. Glucose tracker++ sells 2 in-app purchases, starting at $4.99 per month and Carb Unit Diary for Diabetics sells 8 in-app purchases, starting at $2.49 per 7 days. Whichever you choose, the download price is not the number that matters.

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.
