About this app

Fraudulent calls and nuisance calls are on the rise, and it has become commonplace to avoid receiving calls from unknown numbers.
However, on the other hand, there are many urgent calls from credit card companies that you cannot or would be inconvenient to miss, even if they are from unknown numbers, such as ``Someone is using your card fraudulently.'' Also, during the coronavirus pandemic, many people have been made aware that the telephone is a means of communication that is directly connected to life, as health centers communicate with each other by phone.
Telephones are user-friendly and familiar information tools that are essential for a safe daily life. Worrying about ``scam/nuisance calls'' and ``missing out on important life-related calls or inconvenient calls if you don't pick them up'' are risks that cannot be ignored.
nafuda takes thorough measures against spoofing when registering caller information, and when a call is received from an unknown number*, a highly reliable message containing the "business" is displayed on the incoming call screen, making it easy to decide whether to answer or not. Furthermore, in addition to being displayed when a call is received, the caller's message displayed at the time of a call is registered in the terminal's received history, making it easier for the recipient to determine whether a callback is necessary after receiving a call.
nafuda is a free app that reduces the anxiety of answering incoming calls and allows you to safely and reliably answer incoming calls that would otherwise be inconvenient.
*When receiving a call from a number registered in your smartphone's phonebook, the information in the phonebook will be displayed.
