This ambitious iPad app aims to replace costly and cumbersome printed design documents with a manageable digital archive of customizable plans in PDF format. It allows users to manipulate plans in the field, flip between blueprint versions, and share new designs via cloud services or email. The app eliminates printing costs; reduces time spent managing, updating, and waiting for delivery of plans; and provides instantaneous updates that should eliminate rework costs that can occur from using outdated designs in the field.The company offers a three-tiered pricing plan, which includes a free version for smaller projects (less than 50 sheets).
