Bubble Level it's an useful tool which behaves like a spirit level but is in your pocket!
This bubble level app uses accelerometer sensor to simulate a real spirit level.
A real spirit level is accurate by itself, but an Android application needs to be calibrated on a plumbed surface to achieve precise results.
Differently from other application this Bubble Level is colorful, and you can choose your preferred scheme from the entire rainbow colors!
Hope this option make you happier, colors are very important in life :-)
Last but not least, don't shake up excessively your phone while app is running: this bubble really has a spirit!!!
