RoboKiller for Android

1/8

Many companies use automatic cold calling techniques to try and drum up business. These calls can come through at any time of the day and are difficult to prevent. Thankfully, Robokiller’s algorithm filters spam and robocalls to block them.

Block unwanted calls

Whether it’s telemarketers, robocalls, or some other form of cold-calling scam, you can set the Robokiller app as a blocker. The service involves a monthly subscription, but you can try the app for free for seven days. The following are just some of the features that you'll enjoy. 

Automated blacklist

Robokiller automatically adds spammers to the app’s blacklist. This is regularly updated and available for all users of the app. Robokiller’s algorithm uses audio-fingerprinting technology to block numbers, as well as any unknown caller IDs.

For complete control, you can also add numbers manually to the blacklist, as well as an Allow list. You can temporarily disable the spam blocker too, just in case you’re expecting a call from someone not already listed in your contacts.

Answer Bot

Robocalls are a particularly irritating tactic used by companies, so now you can play them at their own game. The Robokiller app has an Answer Bot service, which lets a robot answer unwanted calls.

Spammers won’t know what’s going on when they’re treated to a rambling answer bot instead of a real person. For once, you can waste their time, and not yours. The app also lets you record spam calls to make sure you haven’t missed anything important (or to have a laugh at a telemarketer’s confusion).

Privacy

The developers also don’t market your details. In other words, you can be sure your information is safe if you use the app.

Reliable call blocker

The subscription model won’t be suitable for everyone. If you experience a high volume of unwanted calls, though, then using Robokiller is a no-brainer. Otherwise, you might want to consider a cheaper alternative like Hiya or Nomorobo.
