Streaks Motivational Calendar uses a simple--and surprisingly effective--concept to motivate you to stay productive. The idea is that you choose a thing you want to do more of, such as exercising, for example. Streaks Motivational Calendar lets you set up an exercising calendar on which you can mark off each day that you exercise with a big red X. Once you have a few days marked off, you'll have a streak.
Streaks Motivational Calendar lets you set up multiple calendars so you can track your progress toward various goals. You can name your calendars for any ongoing task, then simply touch the screen on the calendar to put an X on that day.
The app comes with settings for changing the theme of your calendars, showing an icon badge on your home screen for the currently selected streak, and lets you share your streaks with a friend. It also lets you browse your longest current and past streaks for a given task. Overall, we think this simple app offers a great way to motivate people to continue ongoing tasks using a nice looking, easy-to-use interface.
