Small app to make notes that are stored locally on your device. Uses HTML5 LocalStorage and Service Worker for offline capability.
To use the app simply visit: https://kafeiinteractif.github.io/bulletpad_pwa/
If you are using Chrome on Android, use the menu to add this to your desktop.
Upon loading the site it should stay in your offline cache so you can use it while in airplane mode. After loading the app there is no network activity unless you reload and there is a new version of the app available. All your notes are stored locally - there are no backups and no sync, by design.
This version acts as a "progressive web app"... so this is using Service Worker as opposed to Application Cache for offline functionality. To see an example of Application Cache, look at our bulletpad repo (not bulletpad_pwa). You can find it here: https://github.com/kafeiinteractif/bulletpad
Some of the CSS and example code comes from the "Your first Progressive Web App" tutorial which is available as a Google Codelab: https://codelabs.developers.google.com/codelabs/your-first-pwapp/
