The latest product to be drawn to my attention is the ZchessClock Lite, for the iPhone/iPad. As the name suggests it is a chess clock, and as with most 'lite' products, a fairly simple one. You simply set the number of minutes for the game (which can be different for White and Black), and then start. The display is the old style analog display, and even has the traditional red flag which rises as the minute hand approaches the hour. Unlike to traditional clock, it also has a second hand, so you know exactly how much time is left. Touching the clock face on your half of the iPad stops your clock and starts your opponent.
The other interesting feature is an index of chess club webpages, arranged by country. Possibly in anticipation of this review, the ANU Chess Club is one of the clubs listed!
The product itself is free, although you do need to have an iPod/iPhone/iPad to run it. If you are interested in the package, just search for ZChessClock at the App store, or just click on this link http://itunes.apple.com/us/
