maxis friend finder app must have YOUR authorization. If you didn't authorize then he would not be able to track you.

if you want to find out how he track you, you need to eliminate all the ways he could do so one by one. For example, disable your location tracking in your mobile phone. Only turn on for certain apps that you must have. Don't do foursquare check in and facebook check ins.
