Cleanup Duplicate Contacts is by far the best solution available on your iPhone and iPad to remove multiple duplicate contacts in your address book instantaneously. After Cleanup Duplicate Contacts has worked its magic, your address book will be cleaner, faster and easier to navigate.
This 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.
Merging just happens automatically. All partially matching contact details will be merged under just one contact for better management. The App also works flawlessly with multiple sources like Gmail and iCloud to keep all duplicate contacts centralized.
