Big Night Clock is a small application that displays a large clock on your device’s screen. What makes it different from all others, is the fact that it exploits the ability of the human brain to reconstruct the missing parts of the geometrical figures, in this case the characters that make up the hours and minutes. So even expanding the numbers on the clock as much as to exceed the physical edge of the device, you’ll still be able to figure out the right time, with the advantage of being visible from far away. A great help for those wearing glasses during the day, but don’t wear them while they’re in bed.

It is equipped with a number of customizable settings that combine ease of use and completeness.
You can, directly from the main screen:
- Move the clock’s digits by swiping.
- Pinch to zoom in/out.
- Rotate it by rotating two fingers on screen.

Other settings are available by pressing your device’s "menu" button and selecting the “Customize current preset” option or by double tapping the screen.
From here you can change:
- Selection and name of the active preset. There are three configurable presets. They appear as menu shortcuts.
- Screen brightness.
- Font Color.
- Background color.
- The font to use.
- Display style.
- Border’s thickness.
- Border’s color.
- Clock’s position.

The "Global settings" menu item is where you can:
- Lock the screen, so you do not accidentally move the clock.
- Set the time format AM/PM or 24h.
- Keep the screen on while the phone is charging.
- Keep the screen on while the phone is running on battery.
- Turn off the power when the battery is low.
- Use the "Anti burn in" to avoid this phenomenon. (*)
