I appreciate the effort and work that has went into providing this app, and I can also appreciate the value it could provide.
However, I find a few issues with it that I think would be easy enough to fix, basically regarding the UI.
First, I see no compelling reason for this to be a full screen app. The built in Photos app leaves the status bar at the top and I think Cooliris should too.
Second, the navigation is wrong. A tab bar could be used, or perhaps just more conventional drill down screens as demonstrated in the SDK samples. The existing navigation at the top is confusing and not a standard convention. I'm not sure what the first item (the icon) on the nav bar does.. it seems to be a home page of sorts, but I can't tell what it decides to show by default. Also, the navigation is confusing when you "drill down", as you have to scroll the nav buttons which isn't intuitive.
Third, there are performance problems on my iPhone with the animation effects, it is all a little choppy. It might be best to scale back or eliminate these.
Lastly, the app seems to always want to start up in landscape mode, even when I'm in portrait mode. It adjusts only after the static landscape mode splash has been displayed. Apple suggests not using splash screens anyway- the initial image should be a simplistic view of the UI to give the illusion of a cleaner, faster load.
In general I think you should stick to more commonplace UI standards. Nobody wants to have to learn the custom controls and navigation you've come up with in hopes of being fancy or perhaps just "different."
Anyway, I hope these sound constructive and not rude. I really think you have a great idea for an app, I just think you're trying too hard. People will use it because it offers solid functionality- it will "sell itself"- even though it is free
A more lower frills UI that performs solidly and is in-line with Apple's guidelines and demos would get a lot more mileage I think. I'd be willing to pay a small amount for an app that behaves the way I've outlined here.
