One question

Seems to work great. My only question is this: My sibling has the same 6 digit beginning to the phone number as the one I blocked (we both have those first 6 digits). Will her calls still come through if she is in my contacts?

♡ this app...

LOVE this app... I've tried so many of this type app and to be honest this is truly the only one that works for me. I am using a iPhone 8 with IOS v12.4 I would like to make one suggestion to the app, it would be very useful to me if the app kept a running log each time a number is blocked. Some numbers overtime may not no longer remain problem numbers, by having a running log it would provide data to the user and then we'd have a choice to remove the number from the list making the list alittle shorter...

What a gift. Free. Works. And simple.

Unlike all the other phone blocking software out there, there is no in app purchases required to actually make this useful. Every other phone spam blocking software I’ve seen is 10 bucks a month and it doesn’t even really work because the spammers just keep changing numbers. In fact the other phone blocking software ends up blocking legitimate numbers as much as SPAM
