A mountable Rails engine that collects customer testimonials — text and video — and NPS scores from inside your app. An iOS-style "Enjoying this app?" widget prompts users at moments your code chooses (with built-in throttling), a public page collects testimonials from a shareable link, and a minimal dashboard lets you approve, feature, and excerpt what comes in. Display is headless: approved testimonials are served through your models or an optional JSON API, and you render them with your own markup. Framework-agnostic: no CSS or JS framework required.
