The Beve1

I got this app 3 years ago, I heard somewhere it was good. I only opened it once while bored waiting in line, I "dusted" my duplicates. I opened it again today while upgrading my iPhone, deciding what apps I want to kill. I dusted again and made a few groups. This is a GREAT App if you are like me and have hundreds of disparate friends and acquaintances around the planet. I have a number of mail/phone/message apps each with their own contacts that have vampired from other Apps. You know the deal. This App gathered them all up and "dusted" the dupes!
I found 2 contacts I thought had been lost!! No idea how it is able to get inside all my Apps but better this software than Big Brother. Thanks



The app is in desperate need of an update. I paid for the upgrade but it prompts to purchase the cloud backup option every time you open it, which is extremely frustrating since I back up to the iCloud. The app’s auto-dust feature does not work well, at least on my device running the latest iOS. There is also no support for this app, from the app itself. I was expecting more from a paid app.

Good free app


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