Just a very basic Task List coded in basic JavaScript that works solely on the basic client side.

Basic things that can be done:

• Change the list's title,
• Add a basic task,
• Mark it as done by clicking on it,
• Change its title by basically double-clicking (long-tapping on touch-screen) on the label,
• Delete it by double-clicking (long-tapping on touch-screen) on the mark once it's set as done,
• Get basic help by typing 'help',
• Get a list of commands by typing 'commands',
• Save basically each two minutes,
• Force saving by typing 'save'.
• Use it on your basic sophisticated phone.
