Frog Garden is a free, browser-based to-do list and task manager built around the "eat the frog" productivity method: the idea that you should tackle your most important or dreaded task first.
Every task on your list becomes a frog living in your garden. When you make a frog you name it after a task and set how long you estimate it will take, how long you have been procrastinating on it, and how stressful it feels. Frogs hop around the garden. The more stressful a task, the more restless its frog will behave.
As you actually work on a task, you feed its frog that time. Ten minutes of real work feeds the frog ten minutes. The frog shrinks as it fills up, and once it is fully fed you eat the frog to mark the task complete and add it to your memorial gallery. A "View tasks" list lets you copy all of your tasks, sorted by estimated time to finish. Frog Garden runs entirely in your browser, needs no account, and saves your garden locally with a nostalgic Windows 95 look.
