Case Paper’s FREE Paper Pro mobile app, which provides swift answers to common paper-sourcing questions, continues to fly off the shelves, recently recording its 4,000 download.

The Paper Pro, which was released in 2013, is a handy tool for commercial printers, suppliers, and packaging professionals who need to spec orders, price out options, or calculate quantities and weights. With just a few finger taps, users can copy data for later use or email the results to a client or prospective customer.

The app provides ways to calculate paper M-weights, basis weights, linear footage, as well as price per MSF/MSI. The app also includes converters for paper weight, length, and area; caliper conversions (mil to microns); and tables of U.S. domestic paper averages for paper weights and thicknesses. For technophiles, info buttons provide the specific mathematical formulas for each calculation.
