ReceptionRating · Positive reviews · Number of ratings

Keep Contacts holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: A2Z Groups has 3.9K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Keep Contacts'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

Keep Contacts ships an update every 6 weeks, A2Z Groups every 3 weeks. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
