It pays to have an organized phonebook as it makes getting in touch with your contacts efficient. Imagine having to call someone and toggle between multiple entries because the person has more than one contact number saved on your phone. The Duplicate Contacts Optimizer and Contact Manager application has the best solution to simplify the matter.
Duplicate Contacts Optimizer and Contact Manager is a practical tool that merges duplicate contacts and deletes unused ones and those without names. In addition, it creates a backup file for your phonebook, which you can share on Gmail, Yahoo, Outlook, and other email platforms. This is extremely helpful, especially if you need to replace your device.
This app is free to download and compatible with Android devices.
