TECH2M
Numberbook is a communication app for identifying unfamiliar callers and reducing unwanted phone interruptions. It lets users enter a phone number, review caller or business information, and use a community-based directory when they need more context about an incoming call. The service also brings contacts from social platforms together with the phone book and can highlight popular venues along the way. A phone-number registration screen starts the experience, making Numberbook useful for people who want caller lookup and contact discovery in one Android app.
