A unique and partially useful Contacts app with one serious issue


Alone of all the Contacts apps this remarkable address book will update changes in contact info, such as telephone number, addresses, and job data, through sophisticated web searches. These data changes are periodically presented for user inspection and approval and updating.

PROBLEM ISSUES: UPDATING: If you are unsure of the update info and select that option, no changes will be made, but you also lose the new data and it does not appear to be retrievable. This new data should be stored in a buffer to allow you edit and change contact at will, and only permanently delete when you finalize contact.

NOTES: This is a real deal breaker - Less than hundred words are maintained from original Apple Contact Notes. CircleBack appears to truncate the full length of the Contact Notes. This is totally unacceptable and dooms this app to infrequent use, rather than being a primary go-to app. Until they fix this I’ll use it for updating contacts, but little else. Too bad!

This app rocks!! It's truly a game changer!!

iClub Fan

I initially bought this app to merge my duplicates and to scan the occasional business card but this app does so much more that just that. Capturing contacts through emails I get from clients and then storing those contacts on my phone as a contact is a total game changer for my line of work. I rarely write good reviews on apps but CircleBack has proven to be so valuable to me I had to give them props! It's truly a no brainer!!!

Really handy


I am really enjoying the simple functionality of this app. It works great for scanning business cards, scraping email signatures for contact details, and using social media profiles to keep contacts up to date. My only small frustration is that I seem to have some issues with items I add in the app syncing back to my contacts on Google. Particularly with Notes, it doesn't always make it across and I have lost some data. Other than that, I love it
