Start a 30 Day Free Trial of CallStop. After your trial, for just $3.99 USD per month you can schedule calls effortlessly and protect all of your landlines and cell phone from 100% of spam calls. CallStop uses number forwarding to filter out unwanted calls. If you are using a carrier besides T-Mobile, Verizon, Sprint, AT&T, Boost, Xfinity, Cricket, CenturyLink or MetroPCS and are outside of the United States, you can still use CallStop. However, it's a good idea if you're outside of the United States to check with your carrier first regarding number forwarding and international fees, since your CallStop number is a United States number.

Finally a product that works as advertised and doesn’t waste my money like others. App has completely given me my privacy back from being bothered by unwanted callers, scammers and telemarketers. Thank you. And whenever I have a question about the app the developer is so quick to respond and fix any issues immediately and answer any question. It’s clear the developer cares about his customers that spend their money on the app and wants to keep them as customers. I thought “customer service” was dead till now! Must get app and highly recommended!!!!!

Works like no other!

FINALLY!!!! A app that actually stops unwanted & robo calls. Pretty easy to set up but once you do you are good to go! I haven’t had a unwanted call yet since I downloaded CallStop. I have been using RoboKiller but it only catches about 35 to 40% of robo calls so that means 60% of the calls i have to put up with! I have recently been getting around 8+ calls a day and it’s very irritating when your busy and think it’s someone important and turns out to be some goofball wanting to sell you life insurance! CallStop is the answer to Americas prayers! It really, really, REALLY WORKS!!

If you have tried everything try this

So far this is phenomenal. I will not settle for partial support. If you hired a body guard would you be okay with sometimes they protect you? Exactly. This does the entire job. I’ll update if there’s issues but wow and thank you! Updating again I had one problem and it was solved. Thanks! I’ll come back if there’s an issue

Developer Response ,

Hi, thanks for the helpful review! With CallStop, only members of your whitelist from your contacts or people you add can call you. To make sure that CallStop is filtering calls, you need to have your number forwarded to CallStop. We'll be happy to check that everything is working for you if you shoot us an email at hello@callstop.com! Thank you
