Description
Spirit Level with horizontal angle gauge, vertical angle gauge and bull eye level showing surface inclination. Tool also known as Bubble level, perfect for tilt measurement and surface leveling.
Main Features:
• Calibration - Increases the precision of the spirit level. It compensates for the curvatures of the phone like a protruding camera or buttons. You can calibrate one flat surface (front or back) and one edge. The selected edge will be shown on the bottom-right button.
• Save - Allows you to save the bubble level gauges in a notebook and give it a name.
• Board - Allows you to read the saved bubble level gauges.
• Calibration Time - Allows you to extend the time of calculating results from the sensor giving more stable spirit level results. Devices with a good accelerometer don't need it.
• Secondary Calibration - This option is useful for engineers in extreme cases. If you need to use a different edge or place the phone on the screen (e.g. when working with ceilings), switch the bottom right button to 2 and calibrate for these surfaces. Toggle calibrations depending on the surfaces used.
The precision of this leveling tool depends on the quality of the accelerometer and the correct calibration.

Before I uninstall... Suddenly they want every bit of data I create. I cant imagine why besides to sell it and make more profit off me. I mean it's just a level, why do you need personal data, other app data, network data, storage data, location data, relationship data, DNA data, my sperm count, a stool sample? You know... if my data is so valuable when do I get paid for it? Now I'll uninstall.

App started with some kind of forced pop-up ad agreement and data collection that you could not back out of without agreeing to. I had to crash the app just to not agree. No, thanks, I will use a real level
