## What is QuiltMath?

Plan fabric cuts with clear, offline quilt calculations. Start free with binding strips and yardage, backing layouts, and two-at-a-time half-square triangles. Switch between inches and centimetres and see the assumptions behind each estimate. No account, ads or analytics. Optional Premium is a one-time purchase. It unlocks nine more calculators: Borders, Sashing, Flying Geese, Quarter-Square Triangles, Continuous Bias Binding, Setting Triangles, Diagonal Backing, Precuts and Blocks. Save quilt projects on your device, view labelled plans for all twelve calculators, and save PDF Visual Plans or a complete PDF cutting sheet through the system share sheet. Optional Extra includes all Premium features and adds Quilt Layout Designer. Plan a uniform block grid with optional sashing and borders, see a live preview, and create one connected backing, binding and fabric plan. Extra does not require a separate Premium purchase. Both upgrades are one-time purchases, not subscriptions. Prices are shown in your local currency by the App Store. Restore purchase is available with the same Apple Account. Calculations and PDF creation work offline. An internet connection is needed to buy or restore an upgrade. QuiltMath gives planning estimates, not pattern-specific cutting instructions. Always measure the finished quilt top, check your pattern and make a test unit before cutting all fabric.
