***Cleanup Duplicate Contacts app is now completely FREE*** ***REDUCED FROM $2.99 to $0 FOR A LIMITED PERIOD*** ---- NEW FEATURE: AUTOMATIC CONTACT UPDATE SUGGESTIONS NOW AVAILABLE ON CLEAN UP DUPLICATES APP ---- Cleanup Duplicate Contacts app will automatically suggest contact updates if any of the contacts in your address book have any changes in their contact information such as phone, work email, company, job title, location etc. The Updates feature is powered by our proprietary and secure AI Engine which discovers when important connection details change in your address book, and surfaces new contact info or updates so no contact information in your contact book becomes outdated. 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. - App Features - # Instant Cleanup of Duplicate Contacts # Choose the merge-level you need # Very fast - 5000 contacts centralized in about 45 seconds # Detailed reports of scanned results # Automatic merging of duplicate contacts # Manages multiple contact sources like Gmail and iCloud # Creates a backup of your address book before cleaning # Lets you easily restore backups or a part of a backup # Save and export contacts from your iPhone as a .CSV file # Introducing Email Signature Capture - connect your mailbox for Email Signature Capture and automatically discover new contacts from your email exchanges.
