What happens if I miss a day?
Nothing bad. Your plan carries on and your history stays. Your streak counts the days you do a step, and you can pick it up again tomorrow.
Missing a day is normal. Your plan keeps going and nothing is deleted.
Your streak counts the days in a row with at least one step done. A missed day starts a new streak, but your best streak and all your history stay.
If a time of day keeps not working, change when steps arrive.
