Work as a Set Dresser? Or in Wardrobe? Have you ever looked at a pile of paperwork and thought "Maybe coal mining IS for me"? Simply Input pdf files from the major rental prop and costume houses, (they can email these when you pick up) and use your camera to check off the items. You can also add a note about an item, or manually toggle the check status. Note-The pdfs have to be very square. Scans of physical paperwork will work, if they are square. The originals as emailed by production will always work perfect, scans may miss an item or two. I work as a set dresser, and I made sure this thing works for US at every level. If your phone dies, or it crashes mid check? The Dr writes each check each time, so you pick up where you left off. You doing a wrap off grid? The Dr is all offline, just make sure you get the paperwork imported and the Dr will Check it off. That what he does.
