Bubble Level presents a simple interface - an analog of a carpenter's level. It displays in landscape mode to make it clear to the user which side of the device is the reference side. The bubble animates to reflect the tilt of the device, and a numeric readout displays the tilt in degrees. The sound feedback lets the user know when the device is 'somewhat near', 'very near", and "dead-on' level.

Features:

- Supports angle degree units

- No need for calibration

- Sound follows the bubble positions for easier control

- Lock and unlock modes

- Clean and professional design

- Retinal ready, just more beautiful on retina iPhone and iPad
