iVideoLevel is a tool to measure the vertical or horizontal alignment of a object which is out of range or hard to reach.
Naturally it is also possible to measure the alignment by applying the iPhone to a border of the object.
iVideoLevel is ideal if the test object does not have a plane surface where a conventional spirit level could be applied to.
The angle of deviation can be measured via the artificial horizon.
Photos can be saved with or without the artificial horizon and angle information.

****************************
Features:

- Measurement of the vertical or horizontal alignment of a object with the integrated camera.
- Artificial horizon to display the angle of deviation.
- Photos can be saved for documentation.
- Calibration function for all 4 sides of the iPhone.

****************************

It is recommended to calibrate iVideoLevel before usage.
The calibration function could be found in the setup menu of iVideoLevel.
For precession optimization all 4 sides of the iPhone could be calibrated.

To measure a distant object a central position in front of the object is mandatory.
A wrong perspective could cause measurement errors.
