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.
