If you have bipolar disorder, with its difficult-to-manage mood cycles, in order to function your best, get ahold of your triggers, and help your treater help you, it’s crucial that you chart your moods.

Formerly we encouraged patients to chart their moods with good old pen and paper, checking off boxes and circling numbers. But, a better day has arrived.
