TekTrak. iPhone & Android. Free (2 uses) & Pro ($4.99 / year). Sure, Find My Phone is free on iOS, but if you want something a bit beefier, or you want to recover your Android phone, check out TekTrak. Its location feature is very precise, and offers location history so you can see where it your phone has been and where it is going. Remote lock and wipe lets you secure data from afar, and remote ring lets you hone in on the spot when you get close. You also can send a text to the phone - with a message to whoever is holding it. Location data is real time, and the mapping feature gets you the address in real time as well. You also have control over battery consumption so that the phone does not run out of juice before you can get to it. $4.99 per year is a pretty small price for insurance - its like LoJack for your phone.
