In later versions of this caller id app for iPhone, Truecaller Voice has been introduced allowing high quality voice calls with anyone on Truecaller using data/WiFi, and Group Chats with options of keeping your mobile number private. You can also receive messages only after you accept an invite in this caller identity app.  See our best phone call apps list for more options.



A Great Concept

The whole concept of Truecaller is as cool as it is terrifying. By incorporating a user collaboration format this app compiles all the information provided by you into it's giant database to create a world wide phone book. As of right now, they have over a billion users, and can provide a comprehensive directory of land line, mobile and even pre-paid phone numbers.

You can look up names and numbers, or even have Truecaller sync with your contacts on your phone and social media to gather their information. In some ways this could be considered a little intrusive, and a few people out there may not want all their contact information in one large data base that anyone can find. But if that were the case those people wouldn't have a phone number in the first place, and be living in a Unibomber shack in the woods.

Powerful dialer of truecaller app allows you to make calls directly from the app, use T9 search to call friends quickly, see when your friends are free to talk and see more information about your phonebook contacts. Built in caller identity app messenger gives you free chat with your friends and family on Truecaller to send messages, photos and videos to anyone.

Discovering Who Is Viewing You Comes With A Price

That being said even I am a little skeptical in Truecaller's ability to only provide my phone number to other users and not other personal information. As your number is linked to a profile page, which includes your photo and any other information you want to enter how can they ensure your personal details won't get out there?

You can't even see who's viewed your profile in the free version, that only comes with the purchase of a premium membership. Which can range from $2.99 for a month to $16.99 for a six month membership.

Final Thoughts

I am on the fence when it comes to the Truecaller - Global Phone Directory app. Sure it is a great idea, and I'm quite sure the developers are seeking to provide everyone with an amazing new way to search phone numbers. At the same time with all the concerns regarding telemarketing and identity theft around the globe, Truecaller could end up being a great information gathering tool for these people.

Which goes against everything this app should be about, but unfortunately with the way the digital world works this is a valid issue. This is not one of the best free phone call apps for information gathering purposes and might become an overall nuisance to users.
