ReceptionRating · Positive reviews · Number of ratings

Remove Duplicate Contacts + holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Remove Duplicate Contacts + has 565 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 23% of Remove Duplicate Contacts +'s written reviews are positive against 53% of GroupsPro X's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 20, 2026 and September 21, 2026 respectively.
