NumBuster is an app that helps identify who is behind an unknown phone number. It shows how other users rate the phone number and allows you to express your own opinion. The app provides access to features that help you get the maximum information about a phone number.

Phone Number Check

Enter a phone number manually in the search bar or select it from your iPhone contact list. NumBuster will show what other users think about it and how they rated it. This will help you understand who is associated with the phone number and whether they can be trusted.

Call Blocking

Add a phone number to the block list, and calls or messages from it will no longer be received. The list can be viewed and edited at any time. You can learn how to do this on iPhone in the instructions.

SMS Filtering

Allows you to block messages from specified phone numbers or those containing selected words, such as “promo” or “credit”. It helps reduce the amount of spam and advertising mailings. Read more about SMS spam protection on iPhone in the instructions.

Phone Number Page Rating

Each phone number is assigned a rating that suggests how much the phone number deserves your attention.

Reviews

Reviews left by other users are available on the phone number page. Reviews provide additional context—who this phone number belongs to and how others perceive it.

Emotags

Emotags are emoji tags that can be used to highlight any phone number in the contact list. Indicate whether you trust this phone number or, conversely, if it causes a negative reaction. Other users’ emotags are also visible on the phone number page, which helps recognize unwanted or useful contacts. You can learn how to add your emotags here.

Private Notes

A private note can be added to each phone number. For example, remind yourself who it is or under what circumstances you communicated with them. Comments will be visible only to you. More information on how to add a private note can be found here.

Custom App Icons

In the settings, you can choose alternative NumBuster icons. You can change them at any time and choose a design that suits you specifically. More details on how to change the icon can be found here.

Theoscope

A daily forecast based on your phone number. Theoscope compares your personal energies with the rhythms of the planet and tells you where to expect calm and where to expect change. The forecast helps choose the right time for business, meetings, or relaxation. More about how Theoscope works can be found here.
