Board Cut Optimizer vs Construction Calculator

Buy fewer boards and reduce waste. Board Cut Optimizer turns a list of lengths into a ready-to-use crosscut plan for long stock boards, with saw kerf and end trims included. Try the core optimizer free with orders of up to 3 unique lengths and 30 pieces. Enter the stock length and the required piece lengths and quantities. The app quickly builds a verified plan, while exact optimization works to reduce the amount of material you need. Add an optional price per board to see the planned material cost and a transparent savings estimate. Features: • a verified cutting plan you can use right away; • exact optimization for the fewest boards; • saw-kerf and end-trim allowance support; • material cost and potential savings estimates; • millimeters, centimeters, meters, and inches; • common fractions and feet/inch input for workshop dimensions; • a clear crosscut map for every stock board; • an optional limit on available boards; • named projects and reusable orders saved in history; • readable text reports that follow the app language; • PNG cutting plans for printing and sharing (up to 20 cutting patterns and 32 lengths per pattern); • iPhone and iPad support with light and dark appearance. OPTIMAL is shown only after the app has completed a mathematical proof. The current verified cutting plan remains ready to use while the exact search runs. All calculations run entirely on your device. The app works without accounts, advertising, analytics, or transmitting your orders to the developer.
