Envelope

Envelope is an app that aims to help you use your phone less in a really original way. Basically, you'll have to print out a paper envelope and put your Android device inside. You'll only be allowed to use it to see the time and receive phone calls.

This works for a pretty simple reason: thanks to the capacitive touchscreen technology, you can use the device even if there's a paper covering it. This way, you can use the most basic features of your device (like making calls) directly through the paper.

You can print the envelope out directly from the app's tutorial. It's a simple envelope that shows you the position of the numbers on your phone. And that's it. Aside from the numbers, there's really nothing special about the envelope.

Envelope is an incredibly original app that aims to help you use your Android device less. All you need is a printer and a piece of paper.
