The launch of Xamarin 3 at the end of May brought Xamarin developers access to first-class support for F#, enabling succinct, expressive and functional mobile apps for iOS and Android. We received many great entries, making it difficult to select just two winners.

First place goes to Bernard Hsu for his app Evolution! Evolution is, “a mobile app (iOS written in Xamarin) that demos Evolutionary situations in-silico.” Bernard ported the C# version of Evolution to utilize all of the functional power of F# and will be rewarded with a new Apple Mac Mini for the valiant effort. Congratulations!

Second place goes to Peter Klima’s TripDiary app. TripDiary allows you to track your, “trips to nature, for culture or wherever you want, to go take pictures and make notes during your journey.” TripDiary shows off how to interact with a SQLite database in F#, as well as how to build up a complete user interface with maps, photos, and more. Congratulations, Peter, you’ll soon be sporting a new Samsung Gear Live Watch!


Thank you to everyone who participated in the F# contest! Once again, we are amazed to have such a strong and inspiring community following Xamarin. To show our thanks, everyone who submitted a valid entry to the contest will be receiving a plush Xamarin monkey. If you didn’t manage to get an entry submitted this time, no worries; keep an eye on the Xamarin Blog for future contest announcements!
