ForeFlight claim that you can enter UTM coordinates into ForeFlight: https://support.foreflight.com/hc/en-us/articles/220213388-Does-ForeFlight-support-entering-Military-Grid-Reference-Systems-MGRS-or-UTM-UPS-coordinates- 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-flight/id1241701167?ls=1&mt=8

Programmed in Swift 3. Took an online Udemy iOS course that cost $15, which walks you through developing apps, so wasn't too difficult: https://www.udemy.com/complete-ios-10-developer-course/
