The Quilting Maths app provides the following functions:

Binding -
Using the width and length of the quilt the app can calculate the amount of binding material needed (based on the size of the cut binding strip being used).

Material Needed -
Enter the width of the material being used and the number of patches required, including the patch size. The app calculates the amount of material needed.

Patch Count -
Choose the desired patch type and provide information on the width and length of the available material. The app calculates the number of patches that can be provided by the material.

Setting Triangles -
By providing information on the finished block the app can calculate the size of squares needed to provide the necessary side and corner setting triangles.
