Envelope

About Envelope Android App

Many people feel that they spend too much time on their phones and struggle to find a balance with technology.

Envelope is an app which temporarily transform your phone into a simpler, calmer device, helping you take a break away from your digital world.
Once you've printed and folded our special pdf into an envelope it will turn your phone into a very basic device which can only make and receive calls helping you focus on what’s in front of you.

Printed buttons which subtly light up allow you to dial and take photographs, creating a calm but magical “Envelope User Interface”.

Amazingly, touch screens still work through a layer of paper (you can try it right now!) because they sense the capacitance of your finger which is only slightly affected by the envelope. Existing functions such as fingerprint locking still function, and the user interface of the app is optimised for OLED displays, which means it won’t drain your battery if it’s on all day long.

The app is open source and all code is available on Github
