You can establish exercise routines, diets, new year resolutions and other positive activities with Task:Life.
Using Task:Life you set goals such as going to the gym twice a week or not eating cake five days a week, then track your progress over time.
You record each day if you succeeded yesterday (and are thus encouraged to do the task today, particularly if you didn't manage it yesterday). This is an effective, flexible method of ingraining regular activities into your life.
Task:Life encourages you to exceed your own expectations by tracking the percentage of days you succeed and comparing this with your target. You can view a graphs of your history (and see how your performance has improved over time).
You can choose from several ways to view performance including an overall view, a (custom) windowed view or weekly approach.
