Because I'm a nut for any type of outliner, I bought this through the AppStore. Disappointing. It's true that it is pretty easy to hammer out an outline hierarchy, but after that things fall apart. There is no way to export your outline that I can see (other than cut and paste). You can't change the labeling style. You can't apply type styles by level. It has an unusual method for managing font styles, which I had difficulty figuring out. After playing with the styles a bit, I ended up with garbled looking text. Select Help from the menu and the dialog box says it all: "Help isn't available for Scribe." Maybe this app will evolve, but don't waste your money on it now.
