Am very disappointed in this app.
I did see a few negative reviews prior to buying it, but they seemed to mostly be about jot understanding that you had to pay for this app.
I paid the $2.99 for the pro version, but all it did was mess up my contacts.
I had 3700 contacts, it did reduce them down to 2500, so was very happy and didn't realise I had so many duplicates.
But it was only afterwards when I started going through and trying to ring names, that I realised some people now had two telephones listed for them. Some even had 5 - 6 numbers listed.
This app is very restrictive, it is simply press a button and let them work it all out for you. You can sort buy phone numbers or by emails or addresses or last names. It just sweeps over everything and makes up its own mind where to put stuff.
The other thing is they put down as a selling point that it has a graph, but the graph is big deal, all it does is show what percentage are doubled up and what percentage don't have names listed. There is no advantage to this at all.
I'd strongly recommend you stay away from this app!

July 22 update removed all my contacts!

I downloaded the latest update of July 22nd. As soon as i ran it - it crashed. Then I noticed that all my contacts had disappeared.

Now it just crashes back to the Springboard. Developer replied to my report saying they are working on a fix to submit to Apple. It appears to be connected with having anything at all selected in Settings>General> Accessibility - even just Large Type or Speak Auto-Text.

If your contacts suddenly disappeared please submit a review and let the developers know.

Be Careful buying this app

I recently bout this app because I have in excess of 2500 contacts. For some reason, these contacts duplicated so I looked for a contact cleaner.i bought this App. It found all the duplicates and I then proceeded to merge the duplicates to make 1 contact out of 2. Problem is when you press merge it actually deletes the contact completely. Sent a message to support but still waiting for a reply
