From Manu Et Manu:
Night Clock is the best iPhone clock for your nightstand.* HUGE display font; easy to read* Instant access to backlight brightness adjustment* Portrait and Landscape modes* Disable the iPhone's Auto-Lock for nightstand useThe interface is intentionally clutter-free. Simple is often better!-----Designed specifically for use on your nightstand, Night Clock features a simple user interface and a HUGE font that makes it easy to read the display. Even if you are bleary-eyed and can't find your spectacles, you won't have any trouble reading Night Clock!-----Most iPhones and iPads will automatically turn off the backlight and lock the display after a few minutes of inactivity. This makes sense for most apps, but Night Clock is meant to show the time all night long! To disable Auto-Lock, simply tap anywhere on the screen and press the Padlock icon. When the padlock is closed with "A" the Auto-Lock feature is enabled. When the padlock is opened the display is permanently unlocked.You can also use the brightness controls to adjust the backlight. The dimmest setting is perfect for running overnight. It is still recommended to leave your iPhone or iPad plugged into a charger, even on the lowest brightness setting.The default brightness and locking settings are restored whenever you leave Night Clock.
