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.

Free versions that are better.

It definitely merges contacts and is easy to use, but it will only find contacts with exact matches. It claims it finds partial matches, but idk what that is based on because there were easily 20 contacts with different names same phone number it didn’t identify. I didn’t mind the $2 until I found a free app that cleaned up 30 more “partial contacts” after using this one.

I’ve been struggling with how absolutely horrible iCloud contact duplication for no apparent reason since day 1. My phone has been a mess of 5 of even my own name forever. 2 bucks and a button press got rid of ~2500 duplicate contacts in my phone in about 5 seconds. Some folks have written the thing about consent to share your contacts with their solution - that’s how it works, so whatever. Oddly enough the version of the app I’m using errors out when it tries to backup my contacts so I guess I won twice! Best $2 I’ve ever spent.

Made to pay again!

I had previously purchased this app for my iPhone. Although it was a few years ago, I'm still using the same device and the same AppStore account. But I had to pay again (after the analysis) to be able to merge the contacts lists. That's a shame.
Update: I reached out to them last year and they suggested a solution which didn’t work. I tried to de-dupe again now and the same issue persists. It asks me to update. Now, however, it says I already purchased and that I could update for free. When I accepted the free update though, it failed. This has nothing to do with my payment details or AppStore. Something with this app is not clean.
