About this app

Robocall Blocker is an effective way to end phone spams for good! It eliminates up to 98% of robocalls automatically. Robo Call Blocker is the only call filter you'll ever need to block spam calls & scam calls! The database of spam call blocker analyzes calls instantly and shows you caller ID spam alerts.

Getting lots of spam calls all of a sudden?
Billions of robocalls hit people's cell phones every week. If you are tired of unwanted calls, this spam call blocker can help you get rid of spam calls forever.

• Automatically block robocalls and spam calls
• Identify fraud, spam, and scam before you even pick up
• Control who can call you - add any unwanted callers to your block list
• Get revenge on robocallers with our automated response service
• Phone number lookup

An easy-to-use app with all the features you'd expect from a premium robocall blocking service. Any robocall, telemarketer, unwanted caller, or any phone call with an unknown caller ID will be marked as spam with the help of our number blocking system. Each number that contacts you is run through our call filter's database, and if there's a match, our spam protection engine automatically blocks the spam calls.

Our newest feature allows you to control how aggressive the Robocall blocker should be when blocking unwanted phone calls. Select the blocking mode according to your personal preference!

Create a list of phone numbers and caller-ID names that you simply don’t want to hear from. Any number that is currently on your call block list will be blocked from reaching you.

Lookup the phone number of an unsaved contact to find whether it is likely a telemarketer.

You'll get full caller ID scam alerts. Stop scammers in action after a single ring.

After flagging a caller as spam, Robo Call Blocker sends the spam caller to "Answer Bots," a feature that plays pre-recorded messages to trick telemarketers and other unsolicited callers into thinking they're speaking to a real person.

Everything you do stays on your phone, and your phone only - your data is never shared with any 3rd parties. All reports are fully anonymous.

Not bad! The only thing (and it's not the app's fault) is that valid credit companies that you actually do business with can be flagged by others using the app as spam, blocking their numbers too. It's subjective, really. If I miss my Discover card payment I wouldn't mind a call from them telling me... whereas others who've missed a payment may prefer to mark their collections number as spam so they don't have to talk to them lol. But overall it's easy and you can choose what you want to block!

When it worked it was okay. Very few calls got through but then again, I had registered my number with the FCC and was on the no call list shortly before activating the app. Unfortunately, it disabled my visual voicemail. This is totally unacceptable and an old issue that needs to be addressed. Why isn't there a simple way to fix it? Decided to cancel. Too much work to fix their issues. I can just go back to manual blocking instead of paying to be a beta tester. They only made 5 bucks off me.

I get so many spam calls blocked now its well worth the price. I hate answering the phone while driving or napping only to have it be a scammer. I also like that I can save multiple voicemails. I'm not sure if its the app but when calls end it does not resume paused media, which is slightly annoying but might not be the app.
