#1 Duplicate Contacts Cleanup App for iOS that allows you to easily remove duplicate contacts!

Cleanup Duplicate Contacts is by far the best contact management app solution available on your iPhone and iPad to remove multiple duplicate contacts in your address book instantaneously.

This mobile App runs automatically but you will stay in control. Before scanning your contacts, you can configure the merge level: only detect 100% matches or also detect several kinds of partial matching. After that, it will run a scan to check for all duplicate contacts. Once the scan is complete, it will present you with the results. You can then choose to remove all matching contacts from your address book or to merge only a sub-selection of the duplicates found.

We let you analyse your address book as many times as you need for free. Also, the full preview of duplicates and partial duplicates is free as we want to convince you of the power of our deduplication algorithm.

After you had a chance to review the suggested merges and we convinced you that our algorithm does a great job, you'll be prompted to upgrade to the premium version. Once you upgraded the app once, you will be able to save later analysis results for free as often as you want.

Merging contacts happens automatically. All partially matching contact details will be merged under just one contact for better management. The contact management App also works flawlessly with multiple sources like Gmail and iCloud to keep all duplicate contacts centralised.

Warning! They take your contact data


Make sure you read the privacy policy. This stood out to me and I decided not to use the app as a result.

"With CircleBack, you will always have everything you need to maintain and strengthen your relationships. We do this by using the power of crowdsourcing, in which users of our apps and services contribute their contact data to our Business Contact Database. We use this data, anonymize it, and match it with billions of other data points from millions of other users who have contributed their data as well"

Does not allow you to review merge


The app allows you to review which contacts will be merged, however does not allow you to preview the merged result. In my case, I have several duplicates where one of them has lost the phone categories and the other has not. When this app merged them it took the one without categories for every contact. It also did not automatically backup the merge because it will not do that unless you set up an account, there is no warning or prompt to do this.

Thank you,

Worked well and for free!


This app worked to clean up all my contacts that iCloud somehow duplicated over and over. I tried three other apps and they all required you to pay for "premium" but this one is free and works just as well!
