Interesting thought. Poor implementation. You want money for that? most android devices are full to the brim with sensors such as accelerometers and gyros etc. And this app does what? Nothing. Please use them.
(app dev) Guys, we know it's not perfect but we are working on it - font is hi-res now and landscape is in as well (thanks for idea)!
Looks like a beta version that should be for free Serious limitations - no option to rotate screen, needlessly bad resolution of the font, fixed scrolling speed. Option to change the font and color would be a nice extra.
New rendering engine - a bit smoother, handles pausing (no crashes when switching back to running AirSay)
