Spam texts can be even more harmful than calls because you can be charged for them despite not seeking them out.

A downfall that many apps of this nature tend to fall foul of is the extensive use of ads. With Nomorobo Robocall Blocking, the app design is simple, straightforward, and features no ads.

The app also blocks ads from outside sources, which will prevent annoying pop-ups from interrupting your browsing experience.

Nobody likes getting spam calls. For some, this can become a daily or even an hourly occurrence, and it’s needless to say that this causes huge amounts of frustration.

There are basic methods you can use to try and prevent this, such as blocking individual numbers manually.

This could work if you’re lucky, but most of the time this kind of thing isn’t enough to put a stop to the tirade of spam callers once they’ve got your number.

This is why spam call blocker apps are so popular.

As this article shows, there are lots of third-party apps that do a great job of blocking scam callers.

In this section, we’re going to explain what it is you should be looking out for when you choose a product to block spam calls.

Ease of Use

It’s important to download an app that is easy to use. Some apps are overly complicated, with flashy designs that aren’t very functional. You can check how apps appear by looking at your chosen app store and checking out the screenshots section.

If the interface seems well designed and simple to follow, then that is usually a good sign.

A great way to determine how simplistic and smooth-running an app is is to check out the user reviews section and star rating.

You should definitely look for apps that don’t include unnecessary features, because call blocking apps are designed for a very specific purpose.


You need security when installing any app on your personal device. Some apps have been known to sell data, so it’s worth researching your chosen call blocker to ensure that they aren’t in on some nefarious activities themselves.

VPNs are useful to protect your data, but that’s a whole separate area of technology.

Call Blocking

Call blocking apps use various methods to protect you. Some of them simply block the numbers they can identify as spam, which is useful.

Others have databases that are updated hourly, which means you’re safe from numbers that other users have already reported.

This gives the user extra peace of mind and should be considered. Some apps don’t just block numbers, they send the callers to false conversations in order to frustrate the companies that are spending money to contact people.

This is beneficial to those who want to attack the spam call industry as a whole.


There are many free spam call blocking apps that do the job very well. Premium subscription tiers usually offer a more complicated and detailed service.

This could be useful if you’re running a business, so it’s definitely worth looking into what exactly you’d want from a call blocking app.


With so many apps on the market today, it can be tricky to make a decision. However, there are clearly certain apps that stand out above the rest.

Our picks are all exception apps, but the one that does the best job is most likely Truecaller.

Truecaller has many great free features that do a better job than a lot of paid services.

Their own premium service goes above and beyond what you’d expect of an app.

They’re one of the most popular and most highly rated spam call blocking apps around, and that’s with good reason.

We recommend you check them out if you’re in need of a call blocker for your device. Thanks for reading our round-up of the best spam call blockers!
