I would love to see a version that works better in mobile browsers (cell phones, tablets, etc), or even a downloadable app. When I try to use gmap-pedometer on my iPad, the map tends to jump around a lot. There are no apps I've found that do what this site does, and if there were, I would download it in a heartbeat!
I also found it clunky with IPad, and really think I would use often if if it behaved. Moving the map around is a problem. It doesn't want to move when dragged. A few other things fight with you too. :-/
Presently its shocking on the iPad. Any sort of App or improvement in this would be great!
Native app development is underway. There will be another screencast preview available soon, but see progress as of a few months ago, see: http://www.youtube.com/watch?v=3QfazcOmOFg
Okay, so, it's been more than a year. Any closer to having an app?
