Small app to make notes that are stored locally on your device. Uses HTML5 LocalStorage. This version uses Application Cache for offline functionality.
To use the app simply visit: https://kafeiinteractif.github.io/bulletpad/
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.
If you want a more app-like experience consider the "progressive web app" version of this app which is available here: https://github.com/kafeiinteractif/bulletpad_pwa .
