Frequently Asked Questions
What does restyling change?
It transfers the look and feel of an inspiration app onto your screenshots while keeping your own app content intact.
How does the workflow work?
It goes `get_screenshots` -> `generate_overview` -> `extract_slots`, so the style is applied before the final screens are exported.
What size are the final screenshots?
The output is App Store resolution at 1290x2796, ready for creative testing or store updates.
Is this useful for A/B testing?
Yes. It is a fast way to explore different visual directions without rebuilding the whole design system.
