ReceptionRating · Positive reviews · Number of ratings

Contacts Grouping holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: A2Z Groups has 3.9K ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 37% of Contacts Grouping's written reviews are positive against 82% of A2Z Groups's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Contacts Grouping ships an update every 2 months, A2Z Groups every 3 weeks. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
