Celebrated finish

Effort: Low

What to notice

Completing sign-up brings a burst of confetti and exactly one next step.

How to build it

  1. Say on the confirmation screen what was completed and what happens next.
  2. Stop the effect after about a second and skip it with reduced motion.
  3. Offer one next action, such as setup or invites.

When it backfires

Long effects make people wait for the next action.

Theory behind it

Peak-end rule

People judge an experience mostly by its most intense moment and its end, not its average.

Well supported

Game feel

When motion, sound, and light answer an input instantly and pleasantly, touching becomes fun in itself.
