It looks like there's slightly too much padding and it doesn't quite fit on my phone's screen - it seems designed for a tablet-sized device, but everything I see on the screen would fit very well on a phone screen. Indeed, if I zoom out, everything does fit on the screen properly, it's just that the default zoom means I have to scroll to get around.
But the idea looks useful, and the idea of having it on the device you're always using anyway is sensible.
