ContactSweep - Find Duplicates

Tool that you only need to use once.

Contact Sweep helps you review possible duplicate contacts before you merge them.

The app compares your contacts locally on your device and groups likely matches by shared phone numbers, email addresses, similar names, addresses, and organisations. You can open each match, compare the contact details, choose what to keep, and create a clean merged contact.

Features: • Find possible duplicate and similar contacts • Compare names, phones, emails, addresses, and organizations • Review each match before taking action • Create a new merged contact from selected details • Insert missing details into an existing contact • Keep original contacts unchanged unless you explicitly choose otherwise • Configure country codes to improve phone number matching • Works locally on your device

Contact Sweep is built for careful contact cleanup. It does not automatically delete or modify your contacts without confirmation, so you stay in control of every merge decision.
