Find my lost iphone without app?

How do i track my lost iphone

Call apple! If you still have the box you got it in it contains an IMEI number! Apple can track it ussing that!

You need the app or else it's gone sorry. Apple hasn't made a os so you can just access your computer to find it. You need the app on your phone or your computer to track it

Without the app, there's no way.
