Recent user interface trends featuring "flat design" are embracing simplicity. To accomplish anything that looks simple is quite often difficult; succinct works for interfaces too.
For the Bale Wrap App, all interface elements were chosen carefully to reinforce the simplicity of the application and the data it represents.
To emphasize actual wrapping of a bale, circular sliders were chosen for crucial inputs.
These serve both to break up the visual flow and provide a tactile representation of wrapping done by the product in the field.
