Digitate is an open source application designed for use on the iOS platform, specifically on iPad devices. The application allows scholars and enthusiasts with an interest in the visual and material elements of a cultural artefact to make notes and annotations directly on an image of such an artefact.
For example, a literary scholar might use it to annotate the material or bibliographic elements of a rare text or first edition, while an art historian might do the same on an image of a painting.
Essentially, digitate allows you to add notes to images. These images may be grouped into projects; saved for later use, and exported for sharing and dissemination.
