Great app. I've been helping beta test and it's obvious a lot of effort went into making it look polished and feel responsive. An amazing feat of programming and design magic. Angular, ClojureScript, HTML5 and CSS3 working in concert. Congrats lynaghk and ryan!
You might guess that it is well done from the screenshots, but it is even more polished than I expected. If you we're unsure about native vs PhoneGap, try this out. The one thing that doesn't feel quite right is changing the time of day.
Neither of them were released when we started development. Also, I tend to think that it's better to explicitly manipulate JavaScript data structures through ClojureScript than try to build some potentially leaky abstractions on top of them.
Since ClojureScript's protocols are so flexible, it doesn't take a lot of work to teach ClojureScript about JavaScript---whereas the other direction is much more difficult to get right.
edit// works great on iOS 7 beta 2 ;)
