Reading on iOS devices will go directly to the app, which I appreciate. That said, I would prefer a transitional page to the developer's site with a description first, and then be given the choice to view the app in iTunes or the App Store.
I'm not a Dropbox user yet, but the integration and simplicity of this task manager is pretty sweet. It would feel more mine with alternative background colors. Great job!
The iTunes redirect bothers me too, it's a bit too intrusive and probably heavy on some computers. I am a iOS dev and my links do the same thing.
