Cool App: CircleBack
Update your contact list efficiently with this app.
Actively updating your contact list can be time-consuming. Luckily, CircleBack helps you revise contacts only when necessary. The free app uses patented technology to alert users when a contact’s phone number, address, job or other information changes, so you never have to wonder if the details you’ve previously entered are still relevant. CircleBack can also scan business cards and integrate with email to automatically add new contacts. Circleback.com.
