Several smartphones display colorful grocery shopping and food delivery app screens, featuring food images, prices, offers, and promotional banners, all arranged on a blue background.

Infinity scroll - pinned gallery

A vertical scrolling gallery built for sequential storytelling on mobile

Overview

The pinned gallery format presents content one frame at a time, creating a structured and engaging mobile experience.

On first interaction, the gallery applies a one-time scroll lock, guiding users through each frame in sequence before they exit. Once released, the lock does not re-trigger, and scrolling back up will display only the final frame.

This format is particularly effective for story-driven content such as brand narratives, real-people stories or step-by-step messaging where sequence matters.

Please note: This format is not available as part of an Eclipse takeover package.

Examples

Gousto

Two smartphones display food-related app screens; one shows a Gousto ad with a lemongrass & sticky onion pork burger meal and an Order now button, while the other shows a mostly greyed-out, text-filled interface.
