Ultradian is an easy-to-use ultradian rhythm tracker.  Log your energy levels each hour of the day to generate future energy maps and determine when your prime energy times during each day are.

Rate your energy, focus, and motivation levels each hour of the day. As you begin to build up more data, Ultradian gets smarter and produces more accurate rhythm maps.

Forgot to log an hour or just didn't have the time? Your history section allows you to edit and review all rating throughout the day for every day you've ever tracked.

As you track your productivity each day and build up data, you'll be able to add reports to your Trends screen and see how your productivity varies by day, month, weather, and more!
