The app is capable of a continuous production of drawings. Each drawing starts with a selection of the photos and drawing operations to use. The operations include the drawing of lines and aesthetic curves, enabling an operation without access to the photos as well. The result of the photo-operation selection process is shown as an expression for a moment, followed by the execution of these operations.
The final result of each drawing is stored locally on disk or in iCloud. One of the app settings is the number of drawings to retain (up to 100). The latest results are browsed in the History tab, where the previously created drawings can also be drawn again, deleted, shared, locked - meaning they wont be deleted automatically by the app - or viewed in detail by selecting that drawing.
From the detail view it is also possible to examine the drawing process in a step-by-step view that shows the result of each individual drawing operation in a tree-like layout of the drawing expression.
