Duplicate Contact Manager

The problem we solve

Over the years, contacts quietly pile up duplicates — the same person saved twice from a SIM import, a Google sync and a backup, each entry slightly different. You also end up with invisible and empty contacts, the same number under different names, and the same name split across different numbers. It clutters your phone and makes it hard to know which detail is right.

What it does

A free Android app that scans your contacts and finds the duplicates — matching exact numbers (country codes included), emails and names. You can remove or merge the repeats, clear out invisible and empty contacts, and keep the entry you choose. It also exports your contacts to PDF, CSV or TXT and imports from Excel or CSV. Core detection and clean-up is free; a few advanced actions (exact-number removal and merge) are Pro.
