UTM ForeFlight iPhone/iPad App

Recommended Posts

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

Can you add other features to this app to import other things without having to use iTunes? I'll by that and pay double!

As if version 9.1 of ForeFlight, you can import both user waypoints and user map shapes via air drop or attachment sharing via email attachments so although they both need to be in KML, so you can convert GPX files to KML using Garmin Base Camp. iTunes File Sharing is no longer necessary although that still works as well:

For guidance on using airdrop and file attachment, see: 




However UTM user waypoint entry is still not possible which is what this app fixes.

What language did you program your app in?  Swift?  What was the learning curve like for developing an iOS app?

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/

I forgot about that! Thanks mate. Are you planning on adding a function so that you can put in waypoints in other formats? It's a bit of a pain to manually enter them directly into ForeFlight...

Other formats are supported pretty well in ForeFlight as explained on page 228 of their user manual (see below). They only lacked UTM which is why I created this app. 

Latitude/Longitude Formats

For input of latitude/longitude in User Waypoints or the Search box on the Maps 

page, 4 formats are supported:



DD MM.mm


Examples of these formats using this location 32°44’55.6”N, 80°45’57.6”W are:

DD.dd 32.75N/080.77W

DD MM SS 324456/-0804558

DD MM.mm 3244.93/-08045.96

DD MM SSs 3244556/-08045576
