I have a friend with an Android phone........I have an Apple iPhone 6..I use I cloud to keep track of all my devices. I love it and it comes in handy when I misplace my phone around the house or one of those rare times I leave it at the gym as my black otter case matches the stand on the Elliptical Machine......I have no prob since I use Apple products............My question is What can My friend use to keep track of her phone with a similar type of program she is a non apple user........................She lost her phone yesterday for a couple of hours and found it basically right next to her............Any suggestions appreciated......Jazzlover
