This app was made from my personal needs of listen to web or various app video podcasts while waiting in a long and boring tile with my smartphone in my pocket staying sure that I don't get accidental touches on the display.
Actually what this app does is very simple:
Every time that proximity sensor of your device (ex. the one that turns screen off when you're talking to phone) gets covered, it shows a transparent screen to prevent accidental touches of the display!
Let's say that you have your device in your pocket and you want to listen to your favourite music or podcast on some website, once the phone gets in your pocket it shows the transparent screen and makes sure you don't press some buttons or perform some unexpected actions!
