I just gave it a shot during lunch on Android and the app is missing the OSM data I added to my neighborhood, so I am assuming it's still using their old data and that they'll kick over to the OSM data as part of an update.

From the article:

>Enter Telenav, where I work. We’ve spent approximately a zillion man-years to fix these issues and today we’re announcing navigation using OSM within Scout, our consumer navigation app. We’re starting in the US and on iOS with the rest to follow.

I believe that they might be referring to using OSM data. The Scout app for Android has been around for a while. But the copyright notice in the lower right says "year-year TomTom". So I'm thinking that, yes, there are apps for other platforms but they don't use (at least not completely) OSM data yet.

EDIT: yup, on Android it's missing a bunch of edits I did to OSM in my neighborhood. Some of those edits are probably a couple of years old, so it looks like they haven't switched over on all platforms yet.

It's quote from OP.
