One of the most annoying things that I have to face in my regular life is to receive useless unknown calls either from telemarketers, companies requesting to purchase their products or strangers. There are times when I’m busy in my important work, an unknown call, which is not important, comes and divert my attention. That’s when I wish to know who is calling on my phone before receiving the call so that I can ignore the calls that are not important to me.

Fortunately, I just ran across an iOS app called WhoApp that’s designed to solve my perplexity. Claiming to have the world’s largest address book, it instantly caught my attention. As I installed it on my iPhone and checked out how the app works, it stood up to my billings.

Find the Name and Address of Unknown Callers on iPhone Using WhoApp

As unknown calls ring your iPhone, you will know the name address, a profile picture of the caller, email address, street view and even the map image of the person who’s calling you.

How Does WhoApp Work

Once you have installed this app on your device and set it up, you need to decline an incoming call from an unknown number. Then, this smart app will instantly ring you back with all the needed information including the name, address and more.

If you wish to find out the required information about any number before calling it, all you need to do is enter it in the app’s lookup screen. You will immediately get all the available data.


The app supports only a few carriers including At&T, Verizon, T-Mobile, Sprint, US Cellular and Metro PCS. I wish it were compatible with all the carriers from around the world.

Privacy Issue

This app requires access to your contact list. Though it promises to keep the privacy of your contacts, you might not like to share your contact list details. It’s the only thing that might make you slightly worried about.

But TelTech being a reputed app developer company, you can trust it to keep the privacy of your contact list intact.

Available for Free

WhoApp is available for free on the US App Store. It’s compatible with iPhone, iPad and iPod touch running iOS 9.1 or later.


In terms of usability as well as concept, WhoApp can be a worth try. However, as of now, it seems to have some glitches as it doesn’t work as smoothly as it should. I’m sure once it’s updated and the existed bugs are fixed, it will be highly useful.
