What users say:
* Try it, it's number 1
I can say with confidence it's amazing app It saved a lot of my time since I have most of my contacts without country code Now all setup well Thank you

* Excellent app
I rarely rate 5 stars. This one deserves them! I have tried many contacts managers and so far this app beats them all. I like its ability to fix the phone format, adding the + sign and converting the letters to digits. I strongly recommend while it is free.

* Tech masterpiece
Most advanced and sophisticated app for contacts management! - luck of understanding of short local numbers - luck of understanding abbreviation

* Amazing App
This app is amazing, it helped me delete, clean and simplify my address Book without having the need to sync to my laptop. For a person who's a bit OC this will unify the look and format of your contacts easily! Love it

* Very Happy
I have used many contacts optimizers in the past, but in my opinion this is the best one that I have ever used. It's very clear to me what is occurring as it is, and my address book with many entries survived intact and improved!

* Best contacts optimising app ever
I was struggling to remove duplicate contacts from my phone.i downloaded 10 other apps.but this is the one which does the work best. Thankyou

* Better than perfect
Just takes 10 minutes to clear my 5000 duplicate contacts. Must use app.

A great but flawed app

Contact management is extremely important for all people. And smartphones are dumb at managing contacts. This app helps, however, it seems to have some significant difficulties syncing completely and correctly. After sorting out thousands of contacts, i download the app on another phone with all the same gmail and i cloud and outlook accounts logged into, but the sync has not been able to carry over to the accounts and other devices. This is actually dangerous as it can potentially erase all your hard work, and even create new duplicate contact entries, creating more headache and confusion. Fix the sync to accounts issue and its 5 stars.

I have been wanting an app like this for years!

This app is excellent and works great on my iPhone 7+. I have been wanting an app just like this for years! Now that my contacts are cleaned up its like having a breath of fresh air. I had over 1000+ contacts that kept building up over the years. After running this app I cut my contacts down to about 200. I tried to clean up my contacts before but they just kept coming back. I highly recommend this app to anyone!

Btw, left out one star because there is one section in the automated tools that gives you an impression that you can delete a contact during the automated process and if you try when you save your choices you get an error and have to redo your choices. Super small bug that does not take away from making this a great app.

The perfect solution for contact management!

This app was exactly what I needed. I had been looking on my Mac for a tool to get all my contacts synced. I thought it would be easy but definitely not. Little did I realize the perfect tool was right on my phone. I was able to sync my Office 365 contacts with my iCloud on about 10 seconds. Then everything uploaded to iCloud and now everything is synced with my Mac. Easy peasy. So many other tools too for managing duplicates. Everything worked so well, I was pretty astounded. Can’t remember how much I paid but if whatever it was it was well worth it. I wish I had gone to the app in the first place, I’d could have saved myself about 2 hours of fumbling around.
