How to track my daughters iPhone?

I have an android and my daughter has an iPhone 4s. Is there an app i could have on my android and an app i could download on her iphone to track where she is? I need an app that is available on android and also on iphone so does anyone know the name of one that could work?

There's one but don't rember the name and unless you have a valid reason you don't need to know where your daughter is at all time and evan if you did put it on here phone she could just delete it
