Is there a way to get the phone to tell me my current GPS co-ordinates? Just the co-ordinates on the screen so I can do geocaching.

Maybe there's an app I can get for this? Ive had no luck with any gps stuff tbh Geotagging doesnt seem to do anything, orange maps has a monthly fee and I cant really find a tomtom sort of thing to use instead...hoping this most basic function is available at least somewhere
