Actually, in the beginning I choose to target tablets both because of screen resolution and because Android 3.1 was needed anyway, which was rare on phones at the time.
There are now enough phones with Android 4.x that it makes sense to port at least some of the Sportablet features on a mobile. Also, there are small-screen tablets which don't really work so well with Sportablet, but will work fine with the Uploader.
The Uploader is currently in beta, so the user interface is totally crude and it's mostly meant to test compatibility between phones and garmin devices, just as Sportablet needed. So if you download this app, please send me the log, and add a few details on your phone / garmin device. At this stage, I expect these devices to work:
Forerunner 305 and 205
Forerunner 110 and 210
Edge 305 and 205
Edge 500 and 800
but as usual, there might be hiccups on some mobile phones.
The app is available for free: get it from google play, and remember, send me the log :-). Make sure you get version 1.2 or above, previous versions required an activation code.
