We found checkout or shopping-cart screens in **270 of 809 tracked mobile apps (33.4%)** in our July 2026 analysis. Checkout is a minority pattern, expected mainly in Shopping and Food & Drink. Paywalls appeared in **305 apps (37.7%)**, and a broad in-flow upsell match appeared in **374 apps (46.2%)**, with the latter treated as an upper bound because it also captures subscription upsells. Use checkout for discrete-item commerce, paywalls for subscription products, and treat all checkout prevalence as a lower bound because only captured screens count. The corpus contains 809 apps with at least one captured screenshot, deduplicated by company, with a median of 41 captured screens per app. [Checkout and shopping-cart screens in mobile apps: Lazyweb Research]() Source observed: 2026-10-16T12:01:39.291Z.
