Is there any software to track current location of the cellphone?

Yes there is a software for it, but its not for computer rather its an app for mobile phone, which you have to install in the target phone and you can track their current location LIVE, without even letting the person know.

mSPY is the name of that app. To track their current location, what you need to do is install it _ on the target phone and this app will – transmit all the data online which you can view just by Logging in to your mSPY account.

Other than GPS coordinates, This app also allows you to track their calls, texts, chats, photos and much more.

mSPY is a paid app which you can get it at mSpy.Com. hope this help!
