Online poster buyers struggle to choose a size without seeing it in context. See on Wall adds a 2D wall preview to your Shopify store. Shoppers scan a QR code on desktop, photograph their wall on mobile, then see your posters placed at true scale. Room templates let shoppers skip the photo step entirely. Built-in bookmarking and seven-day session history let them save and revisit favorites.

• 2D wall preview - shoppers see your posters on their actual wall, to scale.
• Works on any device - use a QR code or pick a room template, no app needed.
• Built-in bookmarking and history lets shoppers save and compare posters.
• Track sessions, photo uploads, poster views, and completion rates over 30 days.
• Fully anonymous for shoppers — no accounts, no data stored, photos auto-deleted.
