    "I use this app constantly but it does let some calls come through still but all the apps I have used have done that to some extent. I recommend this to block those robocalls that you get."

    "Lately I have been getting a minimum of 3 spam calls a day. It aggravated me so I went looking for a solution. I downloaded the app called Hiya, and I am so thankful for this app. I was able to put a block on all the calls I didn't want and prevent some from calling. The app also has a feature that will do a reverse search so I can look up the spam number. Its free , so why not give it a chance"

    "I think this can do what I want but it also offers a ton of other features. I think overall this is a good solution but it would take some time to figure out as it has way more options than a typical app like this."
