***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in your address book, and surfaces new contact info or updates so no contact information in your contact book becomes outdated.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.

Finding the contact you actually need gets harder every day — and cleaning it all by hand takes hours. ContactsBye does it in minutes. The new Quick Scan checks your entire address book in one tap and sorts the clutter into clear categories: • Exact duplicates — identical contacts you can merge or delete • Service contacts — taxis, couriers, delivery, repairmen, salons and other one-time numbers • Temporary contacts — "order", "client", "interview", marketplace numbers and everything that lost its relevance long ago • Contacts with no number or data — empty cards where only a name is filled in Review each category, delete it in one tap, or pick contacts one by one — you always see exactly what you're deleting.
