NumBuster Caller ID Widget for Android

Upon installation, NumBuster becomes your default calling application. Our full-screen Caller ID mode needs this to work correctly.

Your standard phone app remains an option, though. To make this happen:

1. Open NumBuster
2. On the main screen, tap “Caller ID Mode”
3. Select “Caller ID widget,”

The call screen will have a floating widget on top.

It shows the same data as our full-screen version.

• Number rating — reflects the phone number trust level based on users reviews
• User tags — e.g. “spam,” “courier,” “bank”
• Reviews — help you understand the purpose of the call based on others’ experiences
• Private notes — a section for your personal comments about the phone number, visible only to you

Feel free to move the widget window—NumBuster will always remember its position on the screen. This choice enables fast responses to unknown calls, saving you valuable time. It’s crucial when frequently communicating with new contacts, such as specialists, technicians, couriers, or business people.

You get the full benefits of the Caller ID feature while keeping your preferred calling app.
