Papyros is a new operating system, currently in development. It uses Google's Material Design and is based on Arch Linux. Take a look at the homepage: papyros.io. There is a progress bar showing the progress of the next release milestone. I have created two widgets to show the progress on the home screen of your Android device.
You can also opt in to get a notification when the progress has been updated.
Thanks to Matthieu De Beule, Pablo Criado, Marek Venc, Hugo Castelani, Marek Pikuła and Mohammed Islem Betta who translated the app into French, Spanish, Czech, Portuguese, Polish and Arabic respectively.
If you want to translate the app into your language, feel free to send me an email at [email protected], or send me a hangout (plus.google.com/+teinvanderlugt1).
