Very snappy on an iPhone 4s in app browser.
Nice animations that aren't overdone, my scroll history is remembered, no scroll jank, no touch latency. Kudos.
Wish more spas worked this well on mobile.
Edit: there's occasionally a touch of repositioning when opening up the homepage again. The Israeli article headline is stuck at the top of the page behind the header for a half a second or so then quickly gets set into place. Definitely still a web app, but it's better than most
