Unwanted calls

I am signed up but still getting robocalls. Your system isn’t working.

$130/yr is expensive!!

Too expensive

It’s a great app but…

So I’ve had Robokiller off and on over the years. It’s a great app.

My problem is that I see nothing that warrants the doubling of the month to month subscription price. That is the only reason I am giving the app 4 stars.

Just canceled my subscription and will be deleting the app next week when my subscription ends.

Scam company

A silent 3x price increase when the app is still letting through spam calls is insane. I guess they're hoping people don't realize the $129.99 price hike and accidently pay. I'll find another app.
