The product pages position it as a tool for responsive testing, mock-up work, and website previews. The pricing page says it supports 35+ mobile devices, while the mockup page provides free high-quality device mockups for popular phones and tablets in downloadable PNG format.
Features
Screenshot capture
Capture high-quality screenshots of simulated mobile views for documentation, sharing, and review.
Screen recording
Record screencasts from within the simulated mobile view to show browsing behavior or present a workflow.
Automated capture

Documentation and review
Capture screenshots of a simulated device view to document changes, gather feedback, or share a specific screen state with teammates or clients.
