QuiltMath is now on the App Store
A quiet companion for the cutting table: turn quilt measurements into fabric estimates and visual plans, right on your iPhone or iPad.
Download QuiltMath on the App Store
Start with three free calculators
Binding strips and yardage, Backing layouts and two-at-a-time half-square triangles are free. Switch between inches and centimetres and see the assumptions behind each result. No account, ads or analytics are needed.
More tools, without a subscription
Premium is an optional one-time purchase. It adds nine calculators, saved projects, full-screen visual plans and PDF exports. Extra includes all Premium features and adds Quilt Layout Designer: a uniform block grid with optional sashing and borders, linked to backing, binding and fabric estimates. You do not need to buy Premium before Extra. Current prices appear in your local currency in the App Store.
Plans you can keep
Preview labelled measurements and save or share a visual plan or complete cutting sheet as an A4 or US Letter PDF. Calculations and PDF creation work offline; buying or restoring an upgrade needs an internet connection.
These are planning estimates, not full-size cutting templates or pattern-specific instructions. Direct in-app printing is not part of this iOS release. Check your pattern, measure the finished quilt top and make a test unit before cutting all your fabric.
Available for iPhone and iPad
QuiltMath 1.5.0 is now released and requires iOS or iPadOS 16.4 or later. All 175 App Store territories, including the EU, are enabled; regional availability changes may take up to 24 hours to appear.
Our knitting companion, KnitMath, is also on the App Store, with gauge tools, yarn planning and a row counter.
