iHandy Level Free

Nivelador iHandy Gratis is a carpentry tool that allows you to level surfaces using only your mobile phone.

However, before yu begin to use it, you have to go through the calibration process, which is explained thorougly in the following 5 steps:

1. Find a flat surface.

2. Keep your device in a vertical position (the way you'd normally use it, with the Start button on the bottom). Put the back edge of your phone on the flat surface, and then press the calibrate button to calibrate the normal mode.

3. Turn your device 90 degrees clockwise, bring it back to the vertical position and put the other edge of your phone (which is now seen as the 'new back edge' because of its changed position) on the flat surface. Next, press the calibrate button and calibrate the horizontal mode.

4. Place the back part of your device against the flat surface, then press the calibrate button to calibrate it facing up.

5. Your phone is ready for use!
