Contacts Duster - Smart Duplicates Cleaner & Reliable Cloud Sync

As soon you open the app you gotta pay something to use. But it says is for "free".

This app steals money from you. Works badly and is high on the list of things not to download. Don't do it you'll be sorry.

I only use it to delete undeleteable contacts from my contacts! <br/><br/>And for that alone i give it *****

Was going to give this app a 4 but w recent iOS update can’t do it. App doesn’t function. Support is a zero star. Impossible to get to an agent. If they contact me I’ll write a better review. For now no.

Locks up at 41% every time and will not finish clean up.

Does a good job with recognizing and merging duplicates - beyond that it seems you need the paid version.

Avoid.

This app works great. This is the only app of this type that i have come across. It is very easy to use and straight forward. Be careful though. If you do actually have two contacts for one person, it will only keep one. look over you contacts before using.
