Calendar App
"Compass is a simple calendar that helps you manage your time. The first-class shortcuts will make it a breeze to stay on top of your schedule, and the minimal UI will help you focus on what matters: your events. It also offers a two-way Google Calendar sync.
The life view shows your existance as a grid of dots. Seeing how few you have left may make you pause before scheduling more busy work.
Compass is open-source and built with React."
