App appears to work... A little!

As a completely blind user of the iPhone, I like to try to find applications that are accessible with voiceover, the built-in screen reader from Apple. This application appears to be accessible, with all buttons properly labeled. The only issue that I had with this application, and I am not sure if it is related to the fact that I downloaded and installed the free version, is the fact that the multiple users, "duplicate" feature doesn't appear to work. Also, the option to sort out zombie contacts doesn't work in this version either. As I said though, this could be directly related to the fact that I am using the free version, versus the paid version. However, this application possibly may be something that I would use in the future, if those features were able to be worked out. A

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.
