Fantastic app that really proves useful in Korea. It really filters out the riff raff and helps me block unwanted spam. I hope to see this in other countries!

Great app. It has prevented me from picking up spam numbers that my caller ID didn't catch. Very nice.

nice handling

Isu. K. Jan 29, 2018     

Bad to use. When the message comes up, two messages are displayed. The original Android message and this app message. It is a bit strange so I deleted it

S.. P. Dec 5, 2017     

It works but the pop up function won't disable. I disabled in settings, blocked notifications from it in my android settings. Pop ups won't stop so I am deleting this app.

Good app. Identifies spam numbers, simple and easy to use. Haven't had any problems with it yet.

Bor. J. S. Sep 15, 2017     

I thought it was a spam app. But i never thought it would be this useful

Dan. K. K. Aug 17, 2017     

Does a great job

후후를 기본 전화로 설정하면 incoming call이 왔을때 벨도 울리지 않고 진동도 동작하지 않습니다. 설정은 모두 확인 했습니다. 완벽하게 어플 자체의 문제입니다.

Very good app~ helps with spam all the time

유초날. Jan 12, 2017     

A very useful application.thank you for the creator for this app. ~~^^

I have used this app for a long time. It does a great job at identifying spammers, but I can't do simple things like paste a phone number to dial it. The interface is a little annoying when I have to close the popup box after a call, especially when I'm in a hurry.

Cin. C. Jan 19, 2017     

Used same kind but Korea app doesn't help it made voice fishing!! Which one is real safe? Really good. It protects spam call. 폰 초기화 이후부터 써비스가 안되네요. 갑자기 대출 스팸문의가 마구 걸려오네요. 차단 부탁드려요. No working nowadays

Saves me picking up calls from all the bogus virtual numbers

Udh. K. M. Aug 11, 2016     

Most of the numbers in my call history are not registered in its database...but my others apps identified those...database limited for Indian mobiles. Otherwise app layout and functions are too good.

A. G. u. Jul 29, 2016     

Quite useful irrespective of some essential functions. To be improved.

Gin. Jul 20, 2016     

Why it was deleted?

I'm not getting the verification code

mic. d. Jul 15, 2016     

Really great app

Dor. G. Jul 8, 2016     

Call blocking app- I don't like that it holds only a certain amt of numbers.

Hik. M. Jul 2, 2016
