Tired of pressing the power button everytime you need to screen off? No more with Gravity Screen. Gravity Screen is a smart, handy tool that automaticlly turns screen ON/OFF using the proximity sensor of your screen.
How it works? It monitors the orientation of the device through the gravity sensor. When your phone is pointing downward by its top, in a certain angle, it's likely to be out of use. In this situation, as you might expect, the screen automaticlly turns off.
What about battery usage? It's not that bad but it may be significant for some phones, though. The usage may use up to 6 percent extra energy of your day.
App is available for free on Google Play but if you like it, consider buying pro version either for supporting the dev and unlocking more features.
