About

Board Cut Optimizer

Features
Read full description

Plan crosscuts for boards, battens and slats before buying material or starting work. Board Cut Optimizer helps home renovators, installation crews, cutting shops and small woodworking businesses turn lengths and quantities into a clear cutting plan. It can help reduce waste and material costs, depending on your order. Enter one stock length, the required part lengths and quantities, saw kerf and end trims. The app builds a verified plan, then uses exact search to look for a solution requiring fewer stock pieces. Optimality is shown only when it has been proved. Use it for shelving parts, battens for lining, decorative slats and repeat batches of wooden products. Calculate each material and cross-section separately, using one stock length per calculation. This is a one-dimensional crosscut planner, not a sheet-nesting, rip-cutting or structural-design tool. TRY BEFORE BUYING Calculate your own orders with up to 3 different lengths and 30 pieces for free. You can run repeated calculations, save results and export reports. You can also view and export the ready-made reference result. Larger orders require full access. FOR THE JOB AND THE WORKSHOP • Saw kerf and end-trim allowances. • Millimeters, centimeters, meters and inches, including fractions and feet/inches. • Cutting maps, saved results that open without recalculation, and readable text reports. • PNG cutting plans for printing or sharing, up to 20 patterns and 32 lengths per pattern. • An optional price per stock piece for estimated material cost and potential savings compared with cutting each requested length separately. Savings are not guaranteed. All calculations run on your device. No account, ads or analytics SDK. Works offline on iPhone and iPad; orders are not sent to the developer. Full access is available as a one-time lifetime purchase or a weekly auto-renewable subscription without a free trial. Both unlock the same features. Prices and terms are shown before purchase; Restore Purchases is available. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
