It found some duplicates, but too many obvious duplicates were left were behind to give this app full marks. It needs more work and I still have the work of cleaning out my considerable merged (iCloud/Google) address book. ### 2/5 — Meh *2015-03-22, version 2.0.9* It was helpful but... Surprised that it doesn't eliminate or merge duplicate names. I'd rather have spent 1.99 elsewhere and had those options as well. Thanks! ### 1/5 — never worked *2014-08-18, version 2.0.9* I have over 3000 contacts and it never found them. always came up with no contacts to back up or clean. I want a refund. ### 1/5 — Useless and dangerous *2014-06-07, version 2.0.9* I bought this to clean duplicate entries in my contacts list. It had exactly the opposite effect: created over 3,000 duplicates and now it's unable to clean them. Not only a waste of money but it can ruin your contacts. Stay away ! ### 5/5 — Easy and effective tool. Every bit as promised *2014-03-23* I am extremely delighted to have cleaned up my long standing duplicates. The program tool is so easy to use and very effective I recommend this to everyone as every bit value for money ### 5/5 — A must have app *2014-03-12, version 2.0.9* Using this app for a while and I love it. Makes managing your contacts much easier! ### 5/5 — Saved me HOURS *2014-03-06* Honestly, we'll worth the .99 I think I might have gone crazy without this app! ### 1/5 — No good *2014-02-24, version 2.0.9* The app hasn't been working for a long time. I clearly have some duplicate contacts but it does not detect them. Will you leave it like this?? ### 1/5 — Does not work *2014-02-17, version 2.0.9* I am sick and tired of paying for apps that do not work. We should be allowed to try the app before buying! I want a refund!!!!!!! ### 1/5 — Poor performance and unresponsive developer *2014-02-06, version 2.0.9* Sadly, this app left hundreds of duplicate contacts in my contact list. I emailed the developer and did not get any response. I would definitely not recommend this app. ## Most critical reviews (10 lowest-rated) ### 1/5 — Veraltet und funktioniert nicht mehr *2021-06-27* Die App fordert den Nutzer beim Start sinnigerweise zu einer Sicherung der Kontakte auf, Stürzt dann aber leider sofort ab. Somit ist die App überhaupt nicht zu verwenden oder zu gebrauchen. ### 1/5 — App abandonnée *2020-11-23* Dommage, plus de mise à jour, plante au démarrage sur iPad Pro 2020 ### 1/5 — Doesn’t work at all *2019-11-23* Does not work at all ### 1/5 — Not q good application *2017-09-30* Wastage of mone ### 1/5 — Contact clean up pro *2017-06-04* Rubbish doesn't work ### 1/5 — No good *2017-03-15, version 2.0.9* I have hundreds of duplicates and it only found 5. What! I could have fixed it faster without the software. ### 1/5 — VAPORWARE!!! *2017-02-17, version 2.0.9* This app hasn't been updated for almost three years. It is not compatible with iOS 10. ### 1/5 — Bad. Doesn't work at all *2016-10-29, version 2.0.9* Refund my money. This ap doesn't work at all ### 1/5 — Waiting for a response from them *2016-05-12, version 2.0.9* AVOID!!! ### 1/5 — Didn't clean any duplicates *2015-08-01, version 2.0.9* Still have hundreds of duplicates in my address book.

(Senior IT Technician) ### 5/5 — Lifesaver *2014-10-19, version 2.0.9* Seems like every time I transfer contacts when I get a new phone, they get all screwed up - duplicates everywhere. This app makes it super easy to correct all that. It works, it's reliable and it's simple to use. Highly recommended ### 5/5 — Automatic feature made it simple *2014-09-07* For years I have had a crazy contact list with 4 and 5 versions of everyone after synching my devices. Trying to fix them one by one was too hard and I gave up. This app did all 2000+ in less than one minute and I feel so much better organized!! Thank you contactclean pro!! ### 5/5 — iPhone merge *2014-08-19, version 2.0.9* I had about 2000 addresses. Many were duplicated up to 16 times! I used the "Autoclean". It ran four or five times gradually reducing and combining addresses. A REAL LIFESAVER! ### 5/5 — Greeeeeeeeeeeeat *2014-08-11, version 2.0.9* Greaaaaaaaaaaat --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
