This is a rudimentary app; overpriced at $4.99. There are three, two-dimensional views: overhead, lateral and frontal. Don't assume 3D with panning and zooming through the sinus regions. You can download the sinus cavities from Google images and save yourself $5. This app is not helpful and has minimal capability.
