When the streak resets
A reset feels like losing everything. It isn't. What to do the morning after.
Everyone misses a day eventually. When it happens, the calendar marks that day in red with a cross and the streak starts again from zero.
Your history stays. Every day you kept is still on the calendar, your longest streak is still recorded, and your next streak starts the moment you tick today's circles.
Look at the pattern
Tap the red day in the calendar to see which task was missed. If the same task keeps breaking your streak, it may belong on fewer days, or as a square. Changing a task's days doesn't change your past days; they keep the schedule they had.
