Forgiving streak

Effort: Medium

What to notice

The streak grows day by day, and a rest day is marked without breaking it.

How to build it

  1. Track a small action people can do every day.
  2. Provide rest days so one gap does not erase the streak.
  3. Show what the habit achieved, not just the count.
