BigBen by Cellphonesoft protects your smartphone from accidental use by locking keys, while displaying a large digital or analog clock. By selectable background images and hourly chimes you can even make your phone look and sound like the famous tower clock in London! The program can also display visible and audible reminders for unattended events, like call or SMS.
