How to utilise this in your designs

You could trigger an upsell right after a likely 'Aha! moment' in a first session, so the offer lands on a peak that users disproportionately remember.

Coloring UI with black-and-white forest bike image by Sarah Holliday, arrow from "See why" text to "ENTER LAKE" button; benefits listed: mood, anxiety, cognition.

Try letting users pick the style of their end-of-year review, so the end of the year feels personal, since the peak-end rule gives endings extra weight.

Red UI card with "So what are you in the mood for?" and buttons: "Be nice" (greyed) and "Be savage" (highlighted) points to pink card with McDonald's logo, headline underlined: "Ba da ba ba back again, are we?"

You could cap an onboarding exercise at 30 seconds, so it ends while still fun, leaving a strong end rather than a tired, drawn-out finish.

Time-limited onboarding

You could experiment with a customisable daily limit on bingeable content, so sessions end on a high before fatigue sours the memory of the end.

'Feed' header, two black screens. Left: dark‑gray quote card (Gandhi). Right: empty state with circular icon, "Enough for now" heading, gray copy, "Reload feed" button. Orange arrow points to heading; three‑dot menu.
Example from

Try creating deliberate peaks by rewarding users with power features at streak milestones, so those high points shape how they remember the experience.

Vertical milestone UI with a "Start your streak" egg icon on day 0 in black/white. Locked milestones at 7, 14, 21, 30 days show rewards and descriptions.
Example from

Possible impacts

Users may be more likely to recommend your product straight after a peak moment or an easy finish, as the peak-end rule shapes how they sum up the experience.

A well-timed nudge

You could increase perceived value by designing memorable peaks, since users often judge a product's worth by its best moments and its ending, not the average.

Timing the upsell

Ending sessions on a high, rather than letting them drag on, might help users remember the experience as more enjoyable, even if the middle was less exciting.
