Provide a managed pre-release testing service built around each app's critical user journeys and established interaction patterns. Testers compare release candidates with the production version, document behavioral regressions, and deliver reproducible evidence ranked by user and retention risk. The service can begin manually and later productize its reusable test library, recording tools, and release-comparison process.

Rapid release cycles and frequent interface experimentation make behavioral regressions easier to introduce. AI-assisted development may increase change volume, while crowded consumer markets make avoidable user frustration more costly.
