Google Envelope
Google Envelope, an experimental app from their Wellbeing project, is exactly as it sounds. These paper envelopes basically transform how your smartphone works: one turns your smartphone into a device that can only make and receive calls, while the second transforms it into a photo and video camera with no screen.

After you remove the phone from the envelope, your device will tell you exactly how long you’ve been using it for. You’ll then have to reset your device as the default phone app, download a PDF envelope and print it now – only the Google Pixel 3a is currently supported. The app can now be downloaded through the Google Play Store.

Many people feel that they spend too much time on their phones and struggle to find a balance with technology. Printed buttons which subtly light up allow you to dial and take photographs. The idea is to try and last as long as possible before opening the envelope,” said the company.
