Both are free to download. Remove Duplicate Contacts + sells 3 one-off in-app purchases and GroupsPro X sells 3 in-app purchases, starting at $0.99 per 6 months. Whichever you choose, the download price is not the number that matters.
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.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 20, 2026 and September 21, 2026 respectively.
