I had to restore my iPhone from iCloud backup. Unfortunately some of my apps are stuck on "Waiting.." stage. One of them is very important for me, it's Stash (http://hedonicsoftware.com/stash.html). It's an application to store documents, photos with password. I tried to find it under App Store -> Purchased tab, but it's not there. I have very important stuff in this app, so I would like to restore the application or the data. I think the app data should be in the cloud, but I can't read/download this data without the app.
What can I do? (I have the latest iOS)
