Shotwell

Shotwell, made by independent San Francisco-based developer Matt, is a screenshot editing application for iPhone that enhances screenshots with device frames, backgrounds, shadows, and other design elements, all processed natively on the phone. It lets users quickly turn plain screenshots into polished, presentation-ready visuals for app store listings, marketing materials, and social media, without needing a desktop design tool. Shotwell is distributed through the Apple App Store, where it maintains its own dedicated listing and branding, alongside a newsletter for updates on new features and future development. Pricing information is presented through the App Store listing rather than the marketing site directly, consistent with a paid iOS app distributed via Apple's standard purchase and subscription mechanisms.
