Designing for Performance and Perceived Speed
Make your app feel fast and responsive by mastering perceived performance techniques, loading states, skeleton screens, and smooth rendering that users actually notice.
Speed Is a Feature
Users abandon slow apps faster than they forgive bugs. But raw speed is only half the story — how fast an app feels matters just as much.
This lesson covers both real and perceived performance.
Perceived vs Actual Performance
Actual performance is measured in milliseconds. Perceived performance is how slow it feels to the user.
Clever feedback can make a 2-second load feel instant, while a blank screen makes 500ms feel broken.
