ReceptionRating · Positive reviews · Number of ratings

Contacts Sync holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Contacts Sync has 15K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 80% of Contacts Sync's written reviews are positive against 100% of Contacts Backup + Restore's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Contacts Sync ships an update every 5 days, Contacts Backup + Restore monthly. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
