Aptus is a dedicated OS X browser that lets you preview, edit and grab screenshots of your site at any size from mobile through to large desktop.
Focus your responsive workflow with a tool that doesn’t rely on bookmarklets, restrictive pre-defined breakpoints - or even a web connection.
Aptus improves on web-based tools by letting you create and work on multiple breakpoints simultaneously, even setting custom user agents if required. Aptus also allows you to preview and debug fluid variations inside your media queries with our unique “Range” functionality - all without having to resize your browser ever again.
Aptus allows you to capture full viewport screenshots of all open breakpoints for sending to clients, supporting blog posts or assessing layout. Of course Aptus doesn’t require a web connection so you can work uninterrupted when traveling or when a connection isn’t available.
NOTE: To buy Aptus via the App Store an Apple account is required.
