YOUR ROUTINE, YOUR POINTS Pick from suggested tasks across 9 categories, from waking up and eating well to workouts, focus, and time with people who matter. Or create your own. You decide how many points each task is worth. REACH 100 TO CLEAR THE DAY Check off what you did and watch the gauge fill. Reach 100 points and the day is cleared. Add more than 100 points' worth of tasks, and you can clear the day without doing everything. A WEEKLY REWARD YOU CHOOSE Earn 600 points in a week and treat yourself to the reward you picked. It's set at 600, not 700, so one slow day won't cost you the week. LEVELS AND WISHES Write one wish for each level. Clear 30 days in a row to level up.
