IT WILL NOT TRANSFER the notes section when merging contacts. ### 4/5 — Well worth it *2020-11-01, version 3.7* I had thousands of duplicates and went to just under 400 or so. I was so happy to see that. The next day I had a ton of spam email though. Not sure if that’s related though ### 2/5 — Paralı ile parasız aynı *2019-01-10, version 3.7* Tekrarlanan 10 numara birleşebilir paralı ile parasıZ farkı yok.Boşuna para vermeyin. ### 5/5 — Excellent work *2018-06-05* Great app , very easy to use and effective, thanks developer ### 4/5 — WORTH $1.99 vs *2018-05-05, version 3.7* Downloaded the Smart Merger app before I found this one and it was free to download but had to purchase subscription to use. Apps are identical but Contact Cleaner was so much more worth the $1.99 ### 5/5 — Good App! *2018-04-28, version 3.7* It's pretty faultless. It's done the job in seconds what would have normally taken me ages. ### 5/5 — Top Contact Manager *2018-03-14, version 3.7* The best contact manager for iphone. 😍Merge,Delete all,Backup😍 ### 5/5 — Super quick and easy *2018-01-04, version 3.6* Was able to quickly delete hundreds of contacts in the matter of five minutes vs hours of going through on my phone and doing it one by one. Well worth the 1.99 ### 5/5 — Great app *2017-11-16, version 3.6* Great app. ### 5/5 — Marwan *2017-10-30, version 3.6* The app is great ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t work *2022-07-14, version 3.7* I have run through the process using every option and yet I am a still seeing multiple duplicates and this is with the pro version and I cannot see anywhere to get support ### 1/5 — Very slow no Benefit *2021-01-17, version 3.7* return my money ### 1/5 — Made a mess of my contacts *2020-03-10, version 3.7* Merged each contact at a company into one contact. Then I couldn’t work out how to revert to the back up or even find the back up. I have also gotten no response from support. It’s been a nightmare trying to fix up everything this app did. Don’t bother. ### 1/5 — Auto merge duplicates not working i wasted my money *2018-02-07, version 3.6* Auto merge duplicates not working i wasted my money ### 1/5 — Useless piece of crap *2018-01-13, version 3.6* Deleted all the contact names and just left the email addresses. What use is that? Then the restore was incorrect. Do not buy this app!!! ### 1/5 — Worst app ever! Erased all my contacts *2017-12-28, version 3.6* This is a terrible app. Don’t buy if you have an iPhone ### 1/5 — Useless and waste of time *2017-12-07, version 3.6* I spent all the time cleaning up and remove duplication, but there’s no way to export the cleaned up list (2000 entries) to a different place: - Move or Copy did not work. I set the target account but after the action when you thought it’s done, there’s nothing in the target account - Share as email only wrote ONE vCard! ### 1/5 — Crashes for me. *2017-11-27, version 3.6* Program crashes messed up my contacts . I wish I had my money back. I can’t recommend. iPhone X IOS11 ### 1/5 — Worst app! *2017-11-20, version 3.6* I followed all the instructions did the back up. It destroyed my contacts! No problem I backed up everything...wrong! When it was suppose to put everything back I had 500 contacts without names and everything was just a mess! This included my husband, my parents, and my best friend. Please do not waste your money to have an app give you a nightmare. ### 1/5 — I take back what I said!! *2017-10-11, version 3.6* This app screwed up all of my contacts. I no longer had names attached to any of the numbers. Good thing I backed my phone to iTunes before hand! ## Most praised reviews (10 highest-rated) ### 5/5 — Great *2022-07-23, version 3.7* I've had this app quite some time now and frankly it's an awesome app I got the paid version after testing and checking it out this is the app for contacts easy to use and a great interface ### 5/5 — Flawless *2022-04-13, version 3.7* This is what I was waiting for ### 5/5 — It Works *2021-06-02, version 3.7* This ap just does what it is intended to do. It manages contacts. Changes my 10+ year old addressbook that was messed with Google emails and FB profiles from 6000+ contacts to relevant 1800 contacts in minutes of fiddling with it. What can be improved: The process of selecting duplicates to be deleted has a back and forth toggling, it can use UI improvement by adding a delete bin in the duplicate selection page. ### 5/5 — Awesome app *2020-10-24, version 3.7* I spent hours trying to find online instructions on how to merge and tidy my contacts. Failed! Eventually found this app, bought it and it did the whole job perfectly in less than two minutes! Fantastic job! ### 5/5 — Wonderful *2020-09-09* Working great It’s save lots of time and energy Simple click to fix all... ### 5/5 — Saved me hours if not days *2019-10-01, version 3.7* Having over 3600 contacts I knew straight out that the process of cleaning up was going to be too time consuming. This cleaner? Let me tell me tell ya, I had my contacts down to 231 in about 30 mins. Very happy! ### 5/5 — Just worked *2019-08-24, version 3.7* $2, download, install, run 20 sec, 500 duplicates merged, done. Doesn’t get better! ### 5/5 — This is the Best *2019-01-29, version 3.7* This is the Best app in this category I love it ❤️❤️🙏 ### 5/5 — Recommended *2018-10-03, version 3.7* Very easy to install and use. ### 5/5 — Easy to use *2018-09-28* High accessibility app --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
