Hope that helps

Just so you know, the app above has a lot of major Voiceover issues and doesn't get the job done, and is a paid app. Over all, a horrible recommendation. I, too, am having issues with this and would like a realistic recommendation that is accessible and effective.

Ok thhen try this

Here's an app that still has some unlabeled buttons. I actually purchased this one a long time ago, so I don't know how much it is. I deleted it a while back because I didn't like something about it--it was so long ago that I can't entirely remember what. Anyway, I just re-downloaded it, restored my in-app purchase, and gave it a go, and it's quite powerful. Like I said, it definitely has some Voiceover issues, but it's usable and intuitive.

I just tested it and it works fine with voice over, the app that you had posted works well too, thanks for your uplifting comments; cheers

Hi brian,
I tested this app and it works perfectly with voice over and it's free; try it

I just cleaned up my duplicates in one click; smiley

Recently, I noticed that I had a mess of duplicates, and some triplicates, in my iPhone contacts. Upon inspection, I saw it was related to Facebook contacts. i checked the Groups setting at the top of the Contacts screen and found several selections for Facebook contacts were enabled, along with my iCloud, GMail, and Hotmail contacts. I selected only one of the Facebook contact settings, and all the duplicates disappeared.

So, in my case anyways, it wasn't a case of actual duplicates, but of a settings issue.

Touche dpi w i
Will have to check my setting too,
Thanks

I tried messing around in those settings before, and I lost contacts that way. I unselected Facebook contacts, and my old exchange contacts, and a bunch of my duplicates disappeared, but so did some contacts entirely. When I went to reselect all contacts to bring back the contacts and just deal with the duplicates, some of my contacts never came back. This could have been a bug in one of the older versions of iOS, but it has kept me from fiddling with those options.

That Cleaner Pro has a free version, too, but I forget how useful it is. So many of these apps show you what they can do with the free version, and then make you pay to actually do it. What's nice about free versions, though, is that you can test accessibility with them and have no skin in the game.

Arvind, you must not be a Voiceover user. If Applevis allowed general submitions, I'd post a review of your app to show you just how wrong you are. Luckily, since there is a free version, people can figure it out on their own.

There is no use arguing with you sam, and i am fully a voice over user, and there is nothing to check,
Most free apps have in app purchases to raemove those annoying adds, this app however is free, just click on the link below and you'll see how easy it is to remove duplicate contacts,

If the app had some in app purchase, i really do not remember paying for it, i may or may not have paid for it,
And sam, you do not have to proof anything,
I have been totally blind and am fully a voice over user,
Well i may be wrong but i think clean up dupes is a good and free app.
Thanks

Arvid, I'm not arguing. I'm simply stating a fact. Here's a link to a brief demonstration of VO issues with this app you are advocating for.

Now sam you got it wrong. The app that you had demonstrated was the first app which i had suggested,. After your first comments however, i checked the app myself and the app indeed was difficult to navigate with all it's unlabelled buttons, but if you were paying attention, you would have realized that i had suggested a 2nd app which is free and is accessible. There are just 2 buttons at the bottom of the app which are unlabelled but it's no rocket science to determine what those buttons do and then label them,
The app you demonstrated was for the first app which is the clean up suite.
I'm not trying to steer up anybody, i was just trying to help by contributing back to the v i / blind society,.
I am pretty sure people would have found the second app much more accessible, the link once again is below;
