It keeps closing out when I click on my yahoo account. I've just spent almost $10 trying to find an ap that will clean up my contacts. ### 1/5 — Useless *2015-03-14, version 4.2* It detects contacts which can be merged but everything is manual and would take forever if you have a lot of contacts like me. ### 1/5 — Auto merge is not working *2015-03-04, version 4.2* Bad bad bad, old version was better. ### 2/5 — Great concept but crashes on all iCloud functions *2015-02-10, version 4.2* I've enjoyed the functionality and usefulness of this app for some time now, but this most recent update should be avoided until the next patch. Every function related to iCloud causes the app to close. Pretty much useless at this point. ### 1/5 — What the ...?!?! *2015-02-09, version 4.1.1* Where is my normal Contacts app? This is awful! ### 1/5 — Worked and now Crashes *2015-02-05, version 4.1.1* It worked fantastic when I downloaded it but now when I launch it "crashes" but it stays in the background. Useless until fixed. ### 1/5 — Dont love this update *2015-02-02, version 4.1.1* Please give us back 4.0 v ### 2/5 — Was good. Now crashes every time. *2015-01-29, version 4.1.1* I've had several versions of this app over the past few years and all of a sudden the most recent update it crashes every single time. Please undo whatever was that you did ### 1/5 — What a waste of money *2015-01-27, version 4.1.1* I have loads of duplicate contacts on my phone which this app wasn't able to recognise which makes is completely useless. I know it was only 79p but I'd rather that be in my pocket than in someone else's for this waste of time. ### 2/5 — Two stars is generous *2015-01-25, version 4.1* I have yet to try restoring my contacts but merge causes the app to crash. Remove duplicate seems to work. ## Most critical reviews (10 lowest-rated) ### 1/5 — Frustrated *2021-03-18* Was really hopeful that this would help me get rid of duplicates but instead it locks up on every option even the help & faq secton ### 1/5 — Hafiz *2020-08-26* Very frustrating . Thanks for the fraud ### 1/5 — Crashes on app launch *2020-05-21, version 4.3* Wanted a straight-forward buy once solution to remove duplicates. I though iOS would have the intelligence to do this automatically but apparently not. Didn’t want an app with any IAP’s so chose this but it crashes on launch. There’s some memory leaks somewhere that need fixing. ### 1/5 — Crash *2020-03-07* This keeps crashing when I try to save or delete contacts. ### 1/5 — Does not work crashes when loaded *2019-01-31, version 4.3* Waste of money loads onto iPad ...then when going to access contacts crashes ...tried it several times ..complete waste of money ### 1/5 — complexity *2016-12-30* The complexity of most application in the Apple ### 1/5 — Don'f buy it! *2016-04-29, version 4.3* I ended up losing some contacts and the duplicates that I originally wanted removed are still there. ### 1/5 — Not helpful *2015-09-08* Waste of my time manually searching through contacts looking for duplicate. ### 1/5 — Would go 0 stars if I could *2015-09-04* Terrible app. Doesn't do the merge functionality it claims to do. Thanks for stealing my $.99 ### 1/5 — Vp *2015-07-28* Didn't work, want $ back ## Most praised reviews (10 highest-rated) ### 5/5 — Yes *2023-10-19* Worked easily ### 5/5 — Great little app *2017-05-01* I am so happy to be able to merge and then delete all the duplicates, i strongly recommend this great little app😀😀 ### 5/5 — Great Tool *2016-12-25* Love it ### 5/5 — روعه *2015-10-30, version 4.3* برنامج ممتاز ### 5/5 — Great *2015-09-22* Great app. ### 5/5 — Great App *2015-09-18* It's a great app offering some convenient features. ### 5/5 — Merge Contacts plus *2015-05-18, version 4.3* This one Really Works! About time someone got it Right- Thank you!!! ### 5/5 — Excellent Duplicate Removal Program *2015-04-11* I used this program for 100's of duplicates on my IPhone 6. I was skeptical because I used another brand of the same item And my results were like 70% at best. This specific program immediately removed all of my duplicates without me doing anything. I downloaded the program from the Apple Store for $.99. Best dollar I have ever spent. I never really saw the Download on my phone. It just opened and did its job. I am sure I must have given the program the go ahead to start removing my tons of triplicates not duplicates! If you need to remove duplicates or triplicates, This is the program for you! ### 5/5 — EXCELLENT ! *2015-02-07, version 4.1.1* QUICK AND EASY TO RENOVATE YOUR DUPLICATE CONTACTS..!! ### 5/5 — Hurrah! Duplicates crunched. *2014-08-18, version 3.3* Alternative backup and sync choices seem to breed duplicates. This is a great antidote. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
