Does what it says; great supplement – CallRanger: Block spam callers Review

This does exactly what I needed it to do: block ranges of numbers. I use this in tandem with with a Hiya-powered blocking system, and this fills in the gaps that the other app/service doesn’t cover. Since telemarketers are constantly switching up phone numbers, it’s difficult for Nomorobo, Hiya, etc. to keep up (though they are *very* good for every other type of spam phone call). That said, telemarketers seem to use numbers from the same block, and Call Blocker makes it easy to define small - or quite large - ranges for blocking. Once you get 2-3 spam calls from similar numbers, it’s easy to have an idea of the range to block, you pop it in the settings, and then you never hear from those folks again. Plus, since it’s only a one-time payment (and low at that), it makes it an easy decision to add as a supplement to a subscription-based blocking service. Great little tool.
