# PreserveAgent ONE vs Remove Duplicate Contacts +

The clearest difference is review sentiment: PreserveAgent ONE at 100% against Remove Duplicate Contacts +'s 23%. Remove Duplicate Contacts +'s advantage is rating (4.5 vs 3.0) and ratings volume (565 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PreserveAgent ONE sells 2 in-app purchases, starting at $0.99 per month and Remove Duplicate Contacts + sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Remove Duplicate Contacts + holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Remove Duplicate Contacts + has 565 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of PreserveAgent ONE's written reviews are positive against 23% of Remove Duplicate Contacts +'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 October 7, 2026 and October 10, 2026 respectively.
