Features:
Caller Identification
Caller identification is a practical feature used to identify unknown incoming calls. You can quickly see the caller's name and location. If the call is business-related, the name of the business will also be displayed. This feature is especially helpful when your call history is cluttered with scam calls and spam.
Blocking Spam Calls
Ever receive thousands of calls in a single day—all of them automated sales pitches? These calls are designed solely to harass everyday users like us. I’ve experienced this myself: I would frequently get spam calls while driving, which severely distracted me.
Robust Fraud Reporting System
The app features a powerful fraud reporting system built on community-driven input. Here’s how it works: when you receive a call, the Numberbook app prompts you to provide the caller's name. Additionally, it offers an option to tag the call as fraudulent.
