Very disappointed. ### 1/5 — Be very careful *2025-12-14, version 7.2.10* I have lost so many contacts when I used this app yesterday. All I can see in my messages are phone numbers for many people. I have to read all the messages to get an idea from whom they were. Unfortunately, it is going to cast me many business contacts. ### 1/5 — Faulty *2025-11-12, version 7.2.10* Glitched & deleted all of my contacts. ### 1/5 — Nothing happens *2025-10-15, version 7.2.10* This app is useless. It takes forever to load contacts and nothing happens when you try to analyze and remove duplicates. The app does not do anything. ### 1/5 — Completely Ruined Contacts *2025-07-19, version 7.2.10* Awful. After running the “clean up”, family contact info was corrupted or deleted. This is an awful app. You have been warned. ### 1/5 — T *2025-04-28, version 7.2.10* It keeps freezing ### 1/5 — Doesn’t do nothing *2025-03-23, version 7.2.10* Just show how many duplicates contacts but you have to do the homework manually! Fake app ### 1/5 — Beware *2025-03-23, version 7.2.10* This app is very glitchy and annoying. You ask it to merge the duplicate record and nothing happens. Now I have Duplicates and Triplicates. And as far as support or help with the app. It doesn’t exist. ## Most praised reviews (10 highest-rated) ### 5/5 — Great app *2026-08-07, version 7.2.12* Truly amazing finding the duplicate contacts ### 5/5 — Good app easy *2026-07-11, version 7.2.12* Like the app simple and efficient ### 5/5 — Works Well!

And free! *2026-06-10, version 7.2.12* This thing is a miracle worker. I had over 22,000 contacts and 20,000 of them were duplicates, partial information, no email or phone, etc. Within about 5 to 7 minutes it merged, appended, deleted, and cleaned everything. And it did it in a way that I knew for sure I wasn’t deleting or emerging anything important It’s a miracle worker! And free!
