Don't waste your money!! Terrible. ### 3/5 — Finally works *2011-02-19, version 1.3* Down loaded many, many times before It worked. ### 1/5 — Terrible *2011-02-10, version 1.2* I didn't read reviews before I downloaded because it said that there were none, but now that I have experienced the app myself, I see what others are saying. This app is BROKEN. It crashes without merging, has no option to turn off the backing up of names, and simply does not work. I'll update my review if they ever fix it. Very disappointed. ### 1/5 — Do not pay even 1 cent. Does not work *2011-01-17, version 1.1* Do not pay even 1 cent. Does not work ### 1/5 — NOT work *2011-01-14, version 1.1* Very bad :-( do not buy this app ### 1/5 — Useless! *2011-01-01, version 1.0* A useless app... save your buck! Takes a long time to look at the contacts then consistently crashes... you cannot recover and must start over each time. I tried Free Memory and a restart of my iPhone and got the same result. Take this down until you get it fixed! Also, I would like Apple to fix MobileMe (finally) so it stops generating duplicates all the time. ## Most critical reviews (10 lowest-rated) ### 1/5 — Clean Up Duplicate Contacts *2020-03-30, version 1.9* App identified 6 duplicates out of 2100 contacts. Many duplicates remain. Don’t waste your money ### 1/5 — Didn’t work! *2019-03-08, version 1.9* Ran this app and it did not function correctly in removing exact duplicate records... don’t buy! ### 1/5 — Failed to do anything *2018-05-21, version 1.9* Just sat there and said “loading contacts” and nothing happened. ### 1/5 — Didn't do as advertised *2014-12-30, version 1.5* A few duplicates were found, but most were left in my contacts. Very disappointed. ### 1/5 — Don't do it *2012-09-29, version 1.4* There is a better app that's much better - it's called duplicates - and does a much better job cleaning up the contacts. This only deletes 100 % matches but the other one combines partial matches if u want it to, which is nice! ### 1/5 — Junk. *2011-11-16, version 1.3* Only works on EXACT dupes with every single field matching. Most dupes have minor differences. LinkedIn imports, outlook data, etc will not be helped. Waste of money. ### 1/5 — Not Good *2011-11-09, version 1.3* Worked ONE Time! Would not recommend. ### 1/5 — Waste of a buck!!!! *2011-11-05, version 1.3* What a piece of crap! this did NOT delete my duplicates! ### 1/5 — got rid of some not all *2011-09-12, version 1.3* didn't do the job ### 1/5 — Worthless ! ZERO STARS ! *2011-06-26, version 1.3* ZERO STARS !!! The only reason I put 1 star is because you cant put ZERO ! Of 100' of identical contacts...IDENTICAL !...it found 4...FOUR ! Ran it many times and it found zero ....ZERO ! which is exactly hiw many stars this app is worth! iTunes should refund EVERYONES money ! ## Most praised reviews (10 highest-rated) ### 5/5 — Best $.99 cents I aver spent *2012-08-04, version 1.4* Evert one of my over 300 contacts were duplicated and after reading articles on line and messing around with settings I had no luck deleting the duplicates. I finally bought this ap an in under a minute the dupes were all deleted. I highly recommend this app. ### 5/5 — Best duplicate delete app *2012-01-07, version 1.3* I had a huge problem where I had two contacts duplicated at total of 75,000 times. This was the sixth duplicate delete app I tried and the only one that worked. So if you are having similar problems where the program needs to work through thousands of duplicates, get this one because the others don't have the muscle to get through it! ### 5/5 — Thank You :)))))) *2012-01-03, version 1.3* I have 10,000 duplicates 1.00$ for this ill pay 50 $ if duplicate issues must have ....., Brooklyn NY ### 5/5 — Mr. Bhimji *2011-11-22, version 1.3* Great app. In less than 3 minutes it deleted more than 1500 duplicate contacts. It saved lots of time for me. Was looking for something like this. ### 5/5 — Well done!!!! *2011-11-04, version 1.3* Just zapped nearly 2,000 exact dups from my family contact database in iCloud.... Still work to do merging, but a great start! ### 5/5 — Great product! *2011-10-18, version 1.3* Just got rid of 3500 duplicates in a few minutes. does what it says it is going to do. Used this on a 4s and it was great! Very pleased. ### 5/5 — The best ever!!!!!! *2011-10-14, version 1.3* The best ever application !!! I had 5659 duplicate contacts and this application delete and fix all of them and with iCloud my iMac iPad and iPhone are clean from duplicates. ### 5/5 — Satisfied *2011-07-20, version 1.3* I installed this app and it did just what it said. I loved it! I had multiple contacts....some things were duplicated more than 200 times. I went from over 3000 to 253 contacts. I cant speak to any crashes, but I am so glad to be rid of all the dupes! ### 5/5 — Worked *2011-02-28, version 1.3* Well worth .99. Did exactly as it was said to. ### 5/5 — Use with confidence *2011-02-19, version 1.3* This app helped me successfully undo the damage caused by MobileMe! Identification & deletion of duplicates was a breeze, on my iPhone and my iPad. I'd like to re-employ MobileMe, but I don't want the experience of doubling and tripling my contacts! This app works because it defines a duplicate in the strict sense of the word. "Partial" dupes are not flagged, because they aren't real duplicates. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
