I have been using many software’s but no software is close to the utility and convenience that Truecaller as a software provides. It is a integrated caller ID service that find the detail of the unknown number that is calling on my phone along with picture and address if available over the net. Not only this, but if I want to block a particular number or number’s it does help me in that as well. It really helps me from SPAM numbers or unwanted calls. Available on all operating software’s and is free of cost, it is a must have app to have for everyone so that while receiving the incoming call we can have the information about caller. Security wise as well this app is a great utility for women’s.
