Truecaller is a well known worldwide number look up service and today it has update its iPhone app to add live Caller ID functionality. The feature has been available for Android for a while but due to restrictions throughout iOS that Apple have placed it has been unavailable. It remains unclear how the company managed to bring the feature to iOS as Apple doesn't provide any such APIs in iOS 9.
The Caller ID feature will automatically provide you with the name of the person calling you, irrespective of whether you have their number in your contact book or not.
Obviously, there is a catch to use the Caller ID feature of Truecaller in iOS is that you must have the app running in the background. For the Android version of the app there is no such requirement.
Truecaller had briefly added Live Caller ID feature to their iOS app in 2014, but the process was cumbersome. It required users to take a screenshot of the number they wanted to look up and then within a few seconds, the app would speak out the name of the caller.
The latest implementation of Caller ID from Truecaller works, but the screenshot suggests that it works in a similar fashion to its Android counterpart — i.e. a small pop up comes up on the screen displaying the caller’s information.
