The built-in Hiya spam filtering on my Samsung phone would sometimes block calls from numbers in my contact list and was still letting some spam calls through. This app allows me to send calls from every number not in my contact list straight to voice-mail and saves me half a dozen spam calls a day. It's easily one of the most useful apps on my phone.

so far just two days into using, the blacklisting feature has been INVALUABLE. I do not think this will last forever because I'm sure the scammers will figure out they just need to change numbers, so at that point I hope the database will be good enough to block those when it comes. the app itself, is fine, but know one thing, app developers ALWAYS change or "update" their apps to make it "better" but never actually helps. I hope that day doesn't come soon. good job developers... for now

A light, useful and discrete app against undesired calls. The app rejects any calls within a blacklist, which is very useful when scammers target you several times a day, which is the case in Bogota. So far very happy with it.
