What's the difference between Emerald Chronometer and Emerald Chronometer HD?
ECHD is for the iPad; EC is for the iPhone and iPod touch.
ECHD runs only on iPad®. EC runs on all iOS devices but on iPads it runs in emulation mode only.
ECHD's options pages have been reformatted for the larger screen (though their function remains the same).
ECHD runs in both landscape and portrait orientations.
The buttons at the bottom left and right don't work for me, although swiping left and right works fine.
We've had a few reports of this problem, all from customers running older versions of iOS (typically iOS 4.2.1). We have heard from them that upgrading to iOS 4.3.3 fixes the problem. (iPads that we own are all at iOS 4.3.x already and we've been unable to reproduce the problem with the simulator running an older version).
