Also relevant to ADHD

Energy can drain slowly, and it's often easier to see a pattern looking back than in the moment. A quick daily note, even just a number, builds a picture you can look back on, share with someone you trust, or take to an appointment.

Log your energy

About 10 seconds. Only the energy level is needed — everything else is optional. Skip days whenever you like.

How much energy do you have? Think about the day as a whole.
Emotional state Optional. Energy and emotions are tracked separately because they don’t always move together.
Anything that might be relevant? Optional. Pick any that apply today or yesterday.

Your last 4 weeks

Your entries will appear here. Patterns become easier to see after a couple of weeks.
