Level HD is an all-in-one system of bubble levels, inclinometer and rulers built from the ground up specifically for the iPad. It includes levels for surface, horizontal, vertical and diagonal measurements, with a detailed calibration system for high precision and accuracy. Multiple rulers, which can measure in both metric and imperial, are included as well. All features are available in a simple to use one-view layout, all on one page for quick access to anything you want to do.

Bubble Levels
4 single-axis bubble levels which cover horizontal, vertical, diagonal and reverse diagonal axis.
A surface bubble level.

Inclinometer
An extremely precise inclinometer with a high contrast, easy to see increment/needle system and degree and radian rotating feedback display which also signals key angles of pi, for quick and obvious common measurements.

Rulers
Mutliple side rulers for measurement in metric (cm) or imperial (inch), and which take the iPad bezel into account for easy and precise measurements - just butt the edge of the iPad against whatever you’re measuring!
