The Oscium engineers and developers have received approval for their application in the App Store, and the application uses Apple’s intuitive multi-touch user interface, clear display and computation power to the full. Their website offers the guidelines on how to use the application and detailing the finger movements needed to navigate through the screens. For example, setting the analog trigger level can be achieved by touching the right side of the screen and swiping in the desired direction (up or down). If you move two fingers apart, you trigger a change in the vertical and horizontal scales. If you want to zoom out, just pinch the screen by moving two fingers toward each other.
