Terrible app – Delete Contacts + Duplicates Review

I have duplicates of all my contacts on my phone. This app removed none of them. It's message to me is that I have "no duplicates." It could be me but I don't think so. I tried every method I could think of to remove the duplicates and I am not new to technology. However none of them work. I Do not recommend this app to anyone.
