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, Robo Call Blocker can help you get rid of spam calls forever..

• Automatically block robocalls and known spam

• Block spam texts and SMS
• 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 from 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 call.

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.

Set filters to organize your text messages into three tabs: Transactions & Promotions and SMS Junk. You won't be notified of any messages placed in the junk section, though you can access it to see which spam texts are marked as junk.

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 as happy as I hoped for

I’m still having a lot of calls coming through. Some are blocked by robocall but quite a few aren’t.

Really useful and effective. Used to have 15-20 spam calls per day. All blocked. The only hiccup was a call from a old friend was silenced also. I am still impressed.

Pick a different app

This app is not for me. And now even after I have deleted it I keep getting notifications popping up once a day that say b23 with a picture of the app right beside it. No idea what b23 even means. But do not download this app on your phone.
