As a heavy user of the built-in mac and windows sticky notes applications, I wanted something similar that would persist between all of my devices. Another feature I wanted was the ability to share notes with other people and edit them together. That's why I built Cloud Stickiez, a web application that lets you create sticky notes online, organize them in boards, and share your boards with other people. I started this project a few years ago but I didn't get a chance to add the collaboration features until recently. I built this using Angular and Firebase because they were technologies that I wanted to try out at the time.
