I have 2.7K and 30% are duplicates. App showed me only 14 so even with its useless feature to show duplicates it failed! PS No, there's no delete contact button. Instead there is "download out 2nd app to delete" ugly message. ### 1/5 — Useless!!!! Don't download *2012-08-12, version 1.2* Should not even create such app Horrible way to promote your other apps!!! Bought another app and happy Will never buy from such smart €£^^%%^^ ### 1/5 — Just shows! *2011-11-25, version 1.1* Does not have the ability to delete... :( ### 1/5 — The 1st writer said way to try b4 you buy??? *2011-11-25, version 1.1* Give me a break. Sure it's pretty quick but read again what it does and doesn't do. Apple people want something that fix and solves the problem. Not something that "hey if you. Buy This and it MIGHT fix it" This is a horrible way to promote software. Show you what it might do then state if you buy it it will delete the dupes, HEY DIDN'T contacts have that not to long ago. Anyway, it might not work. Will they give you your money back? No. It's stuff like this that creates piracy and the liked. RELEASE A 30 DAY TRIAL AS PEOPLE AREN'T GOING TO THINK, a HA, I'LL NEVER NEED THIS AGAIN. Contacts mess up all the time, especially with a NEW OS or SOFTWARE UPDATE and of course, T-I-M-E!!! Give us something we can try for goodness sakes. ### 5/5 — Way to try b4 u buy! *2011-07-27, version 1.1* There are a *zillion* de-duplicate contact apps out there - all w mixed reviews. Kudos to this developer for showing u what duplicates it's going to delete & letting u decide if this is what u want b4 u spend yr hard earned cents! All the results look great - I won't buy the paid app til it recognizes a few of my duplicate contacts have different images. What would also be awesome is an app that did both deleting of exact matches & an optional merge. Most of the time I just want to remove exact duplicates (like this app) and an occasional merge (but not as frequently since it is potentially destructive) Pls notify me when u fix the bug or if u make the enhancement to toggle an optional merge! ## Frequently asked questions about Show Duplicate Contacts ### Does Show Duplicate Contacts delete duplicate contacts?
