ForeFlight claim that you can enter UTM coordinates into ForeFlight: https://support.foreflight.com/hc/en-us ... ordinates-

In my experience, this is not the case and it's very frustrating, as many clients I work with use UTM coordinates.

I therefore created an iPhone/iPad app, that converts UTM into Lat/Lon and then exports them directly into ForeFlight.

It can be purchased in the app store: https://itunes.apple.com/us/app/utm-for ... ?ls=1&mt=8
