App Store Screenshot Studio

Turn simulator captures into polished App Store screenshot sets.

Included in npm 2.8.0 and later. Your images stay local.

Choose a layout, supply factual copy, compare variants and export PNGs after validation and a visual review. Keep using the existing simulator tools or your UI-test capture workflow.

Real captures. Three design directions.

Five Reading List simulator states rendered in minimal, dark-premium and gradient layouts. Each row is a variant; screen order is preserved. These are marketing compositions of existing captures.

Five Reading List screens in three English screenshot layouts — English · 15 images · 1260 × 2736 per export

Pixel profiles checked 2026-09-29 against Apple’s screenshot specifications. Recheck requirements for your app before submission. Passing checks is not Apple approval.

Neutral frames are programmatic, not official Apple artwork. Original proportions stay intact. Text panels sit outside app UI. Existing catalog colors can inspire the accent; source assets are never modified.

Translation is supplied, not performed online. Font coverage and overflow must pass. RTL layouts support single-direction copy; mixed-direction text is rejected. Human review is still needed for app content, claims and typography. Local manifests contain source paths—review them before sharing.
