QuiltMath and KnitMath: October update
Both craft apps are on the App Store. Updated October 22: the current releases are QuiltMath 1.5.2 and KnitMath 1.0.3, with free tools to start and optional one-time upgrades.
QuiltMath: from measurements to a cutting plan
Binding, Backing and two-at-a-time HST calculations are free. Premium adds nine more calculators, saved projects, visual PDF plans and a PDF cutting sheet. Extra includes all Premium features and adds Quilt Layout Designer, joining a block grid, sashing, borders, backing and binding in one plan.
PDF plans are intended for reference at the cutting table. Direct in-app printing and full-size cutting templates are not included.

KnitMath: from a swatch to a project
Gauge calculations, a row counter, the needle and hook reference and one saved project are free. Premium adds yarn and skein estimates, yarn substitution, evenly spaced increases and decreases, handmade price drafts, unlimited projects, result cards and project PDFs.
Use the PDF to keep your gauge, yarn quantities, price estimate and calculation assumptions together. Check your swatch and pattern before committing to a project.

One-time upgrades, local projects
These upgrades are purchases, not subscriptions. Extra already includes QuiltMath Premium. Prices appear in your local App Store currency. To recover an upgrade, use Restore purchase with the same Apple Account.
Calculations, saved projects and PDF creation run on your device. Buying or restoring an upgrade requires internet. Neither craft app requires an app account or includes ads or analytics.
October maintenance updates
QuiltMath 1.5.2 is available on the App Store as of October 19, with quilt-calculation and PDF corrections and an optional rating prompt after continued use. KnitMath 1.0.3 is available as of October 19, with consistent price formatting, purchase-cancellation handling and the delayed rating prompt.
For help or a calculation that does not look right, email the studio with the app version, inputs and expected result. Never include an Apple password or payment details.
