Works good

I've tried other blockers and most blocked calls that I didn't want blocked. Some would block only part time. This one works great just like it should, every time!

This app half the time doesn’t work

I have had this downloaded on my phone for about 1 1/2 years when I get a unknown call I use this app to identify the caller half the Time it goes through a stupid cycle checking my account or it goes to some stupid thing pops saying unable to process so I used Mr number that helps it’s better than Call Guardian I agree since I had us cellular I get spam callers everyday at least 5 calls I report every call a lot of scammers and fraudulent callers as well. I won’t use this app no more it doesn’t do what it’s intended to do.

Doesnt seem to do a thing

Nit quite sure why i would pay for this after the 99 days free. So far this has done nothing to block ANY of the calls i get as most are spoofed numbers etc. as well as the fact for “premium” it doesnt give me any other caller info than i had for free or searching in google. Seems like a great sell for a useless product. Will finish the free 90 days to see if maybe it improves over time but doubtful
