Nag me notifies users of routine tasks. Nag me notifications are soft (doesn't ring and auto closes) so use it for low priority tasks only. Some use cases of Nag Me are to notify to drink water, to take a walk, to relax your eyes and so on while you are on your computer. Nag Me works in Google Chrome, Firefox, and Opera.
I used React (Create React App), Redux, Immutable.js, Jest, React-Motion, and styled-components for Nag Me. I utilized WebExtensions API along with Mozilla's webextension-polyfill.
