Best Call Blockers for Android

Today’s world is a highly competitive one. Dozens of companies are eager to offer us their services. In their desire to grab our attention, they stop at almost nothing. Hardly anyone enjoys receiving piles of flyers in their mailbox every other day, and most of us have fled from that one particularly annoying promoter in the street at least once. However, irritating spam is much harder to avoid when it comes to buzzing right on your phone.

Besides, phone calls are a favourite tool for all kinds of fraudsters and scammers. Presenting themselves as bank clerks, Amazon, a governmental agency or someone likewise important, they use various tricks or even psychological pressure to fool you out of money or personal information.

Of course, you can Google each unknown number before picking up the phone. Or you can block the number in your phone settings. But to do that, you will have to pick up the phone first and figure out if it is actually a scammer or just your aunt Olivia from Texas who got a new phone.

Luckily, you will not have to go through these ordeals, thanks to a wide variety of call blocking apps available on the market today. Here is a list of the most popular ones:


Truecaller proudly presents itself as “the world’s best caller ID & spam blocking app”, and it fulfils the promise. The application automatically detects and blocks calls and messages from robots, telemarketers, spammers, fraudsters and other unwanted contacts. There are additional blocking options, such as by country, by sequence and more. You can rest assured that no spammer will reach you, and yet, you will miss no significant call. The app offers the largest database of numbers which is updated daily by millions of users.

However, Truecaller is not just another simple blocking app. You can get a pack of additional goodies for a fee, including voice calls and call recording, extra contacts requests, the ability to see who viewed your profile and an ad-free experience.

Should I Answer?

Should I Answer? offers two levels of protection from undesired calls and messages. Whenever an unknown number calls you, the app searches for it in its database. If the number is reported malicious or otherwise unwanted, the app will warn you against answering it. Optionally, you can make the app block such numbers automatically, so the caller will not be able to reach you. It doesn’t matter if the number is a premium, hidden or foreign one — the app can block them all.

As in Truecaller, the database of numbers is composed by the users of the app. They anonymously rate unknown calls as safe or unwanted. Each report is then verified by admins of the app. So, if you have been planning to have sweet revenge on your ex by putting their number in the spam list, your plan will surely fail.

Should I Answer? protects you even at times when your phone does not have an Internet connection. All you need to do is to update the database of numbers from time to time using wi-fi.

Should I Answer? is also a fully functional dialer app where you can find your complete call history and contacts.


If you want more than just another call blocking app, take a look at CallApp. This exceptional piece of software is a fully functional call blocker that can identify the caller, block spam, robocalls, sales or unknown calls. You can also create a custom blacklist to block calls from your contact list, dialer or any phone number that you want. CallApp can identify the caller even if they call from a messenger app such as WhatsApp or send you SMSs. On top of that, the app offers a few catching perks, for example, analytics of your phone calls. It includes the duration of your incoming and outgoing calls, contacts that call you the most, the amount of spam and a lot more. Another unique feature of CallApp is video ringtones. You can set a video to play on the screen of your phone when someone is calling you. Besides, CallApp has a built-in call recorder that is easy to use and works on any Android device. This feature is helpful if you want to prove a scam or are afraid to forget details of an important call.

And last but not least is incognito calling. If you need more privacy, you can hide your phone number while calling through the app. Just be sure not to use this feature for malicious purposes, or you will be blocked too!
