I downloaded it for grins and that's what I got! Yes, too small for anything but novelty (these old eyes couldn't read anything, navigated through familiarity w/ windows). I could guess it would actually be useful/functional on a tablet. Heck, If it had 2 finger screen zoom, it would be fine on a smartphone. Caught myself several times trying to zoom the screen!!LOL Still a fun app with potential if the devs make a few tweaks IMO.
