Verdict
The clearest difference is ratings volume: Contacts Sync at 15K against Contacts Backup + Restore's 7. Contacts Sync also leads on update cadence (every 5 days vs monthly).

Both are free to download. Contacts Sync sells 7 in-app purchases, starting at $1.99 per 7 days and Contacts Backup + Restore sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
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.
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.
