Hold to mark a habit complete, keep to-dos alongside it and turn a recurring to-do into a habit. Optional reminders help you remember what matters. TURN PROGRESS INTO A COLLECTION Start with a welcome gift of 10 Ember. Complete all of today's scheduled habits to earn 10 more, with another 10 for every 7 consecutive perfect days. Each draw costs 10 Ember and reveals a card you do not yet own. Collect two series: 22 illustrated Nocturne Arcana cards and 24 felted Habit Figures, with no duplicates within a series. Switch series anytime in Collection or Settings; each series keeps its own progress. To-dos do not earn Ember. Ember cannot be bought, traded or redeemed for money. Cards are for collecting and sharing. No fortune-telling features are included. SEE YOUR PROGRESS Review weekly, monthly and yearly completion rates.
