NumBuster identifies unknown callers by displaying their real name for incoming calls and phone numbers. It also allows you to block unwanted calls and SMS messages. The app utilizes an offline database of scammers and spammers, and leverages a community-driven knowledge exchange to identify numbers.
The caller ID works through an anonymous exchange of knowledge about telephone numbers between all NumBuster users. When you receive a call from an unfamiliar number, the app checks its database and community information to display the caller's name, helping you understand who is calling.
The application offers free features, including identifying unknown callers and blocking calls/SMS. However, it also has paid features available through subscriptions. Payments are confirmed in iTunes, and subscriptions auto-renew unless canceled 24 hours prior.
The app can identify and block a wide range of numbers, including those associated with fraudsters, advertising (spam), collectors, car dealers, and financial pyramids. It also helps identify calls from banks, shops, insurance companies, and robocalls, including virtual phone numbers.
NumBuster states that your phone number is only visible to those you call. They carefully protect your data, contact lists, and call logs from intruders and do not use them in any wrong behavior. No name search is available in the app, and no one, including moderators, can access your data or contact contents.
