Truecaller, which allows smartphone owners to see who is calling them, has been available for Windows Phone owners for some time. Today, a new update for the app has been released specifically for Windows Phone 8.1 users that adds real-time Caller ID features.

Truecaller claims they have the first Windows Phone app that provides live Caller ID features. It states, "Now, when Truecaller users are using a 3G or WiFi connection, live Caller ID will identify numbers from all over the world, even if it is beyond what is written in the user's contact books. Not only will Truecaller show the names of incoming calls that are not in your phonebook, but it will also notify you if one of those calls is a spam call reported by the 85-million user Truecaller Community."

Truecaller worked in partnership with Microsoft to add this new feature in their app. The company quotes Mikael Stendahl, Head of Partner and Developer Relations at Microsoft, as saying:

"We are very happy to be able to support Truecaller in bringing this great functionality globally to Windows Phone for the first time. Our partnership goes back several years and we have seen that Truecaller is a very dedicated company focused on delivering a great service for its users."

Windows Phone Lumia users who update the Truecaller app to the new 4.2 version by October 30 will also get 30 days of free Premium access.

Please note that it does require Windows Phone 8.1 to work, and it may be just for Lumia devices as it also needs the Network+ update.
