Contacts Optimizer Customer Insights

1. Try it for yourself.Great app! Free version identified duplicate contacts -- and which fields were the same -- in seconds and gave me the ability to choose which contacts to merge (as opposed to all or none).

2. I'm didn't sign up for being a beta tester.Read on a forum post that this application is capable of removing duplicate phone numbers within the same contact.

3. Some of my contacts had up to 4 of the same numbers saved as one contact which was really frustrating as when I used to search for a contact and a list of the same numbers used to show but this app actually got rid of it.

4. I had over 1500 duplicate contacts, still from the apps initial first start-up to the time it sifted through to a finish was less than 90 seconds.

5. If this can actually do this gimping the preview / free version for fear of losing sales just did the opposite.I've used this for a few years but never wanted to leave a rating which might discredit the hard work.

6. This app optimized my contact list by removing duplicate numbers on my contact list.

7. The greatest frustration is this apps blindness to even the most obvious duplicates and insistence on the duplicate nature of contacts which are not.

8. Because who else had gotten sick of having to SEPARATELY click "download" on each INDIVIDUAL one your photos and videos when you've had to recover them? Enough of my rant, thank you MobilEdit/Compelson Labs and happy holidays.Needs much more refinement of filters, matches, suggestions, and user interface.

9. When I tried to purchase Pro version, I got a message from Google that they were going to store my payment info.

10. I believe you guys have the potential to craft the first app that will assist with duplicate Google photos, along with making bulk downloads a possiblity.

11. tried using other waste of time apps but didn't work.
