Are there any good apps to track my lost iphone for free?

I lost my iphone at one of my relatives house and I can't find it anywhere. Are there any good free apps out there that I can use on somebody else's phone to find or track my iphone? I just want to know whether anyone has stolen it or not. If I know that it is still in my relatives house I can relax. Keep in mind though that my iphone is switched off.

Log onto your Icloud! It can tell you the location of your phone as long as it is still turned on. Plus, if you can see that it's in a place that may mean it's been stolen you can disable your phone from there so no one can get into it.

To locate your iPhone download the "Find iPhone" application. On the application sign-in with your Apple ID and you will be able to locate your phone provided that it's turned on. In your case it's turned off meaning there's no way to track it.

Well actually Find My iPhone is set up before loosing the iPhone n nw after loosing it you can't set it up but if you have any other apple ipod or iPad or any other iPhone den login from your apple ID used in your own iphone n den maybe Find my iPhone can help you.

Use your iCloud to track your phone. That is the most accurate app/software available. Hope this helps you.
