HUD (Headup display) - Free

A head-up display or heads-up display—also known as a HUD—is any transparent display that presents data without requiring users to look away from their usual viewpoints. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments.

This app uses your compass, rotation sensors and GPS to render a head-up display. GPS is used for displaying kilometer per hour on the left side, height in meters above sea level on the right side and time on the bottom of the display. The inclination angle is in degrees.

The camera previews always have a little delay, therefore consider this app as a toy. Do not use this as a real head-up display as you might endanger others.
