So I'm a dev who spent 10 minutes just now with Jetstrap and Froont; Jetstrap has component items such as 'navigation' etc., which can be easily tossed in. Froont has break points for responsive design. So while Jetstrap allows you to view the result on iPhone v. desktop; Froont allows you to set up very different parameters that change responsively to screen size 'break pointss'... or am I missing that feature in Jetstrap?
