Five Second Test

Five Second Test (Lyssna) Freemium Beginner

A fast way to check whether a screen reads clearly in the first impression, which is often where clunky starts. Show people a screen for five seconds and ask what they remember or where they would tap. Cheap and quick enough to run before and after a change to confirm you actually made it clearer.

  • Measure first impressions of a single screen in seconds
  • If people cannot tell what to do fast, the screen needs work
  • Run it before and after a change to confirm the fix landed

It answers 2 questions

  1. I keep tweaking the landing page instead of launching. How do I tell polishing from procrastinating?
  2. How do I turn vague feedback like "the app feels clunky" into specific design changes I can actually make?
