I am using OSM in my smartphone with Firefox OS and it have been a great experience so long!
My two favourites apps are Lantea Maps and Here-I-am. Tomorrow I'm gonna try Track Guide out.

Thanks for the tip! I've been hoping for a nice OSM app for FxOS - will try out Lantea Maps :)

I've been thinking on getting a smartphone with Firefox OS... I've been using OSMAnd http://osmand.net/ on Android (I wish it had a version for Firefox OS.). Recently I tried out two apps for Firefox OS on my Android (yes, it is possible!), tried Evernav https://marketplace.firefox.com/app/evernav and Kosmos Maps https://marketplace.firefox.com/app/kosmos-maps, they look good, but I couldn't try too much, they became heavy using them on Firefox on Android in a just fair hardware (Xperia Mini Pro, sk17a).
