KnitMath is now on the App Store
A pocket calculator for the knitting bag: turn a gauge swatch into cast-on stitches, yarn amounts and a handmade price draft, right on your iPhone or iPad.
Download KnitMath on the App Store
Start with free gauge tools
Gauge, the needle and hook reference, a row/round counter and one saved project are free. Convert a swatch into cast-on stitches and see every assumption behind the result — no account, ads or analytics involved.
More tools, without a subscription
Premium is an optional one-time purchase, not a subscription. It adds Yardage and skeins estimates with leftovers, a handmade price draft (EUR, USD and GBP), yarn substitution, an even increase/decrease spacing calculator, unlimited saved projects and PDF or image export. Current prices appear in your local currency in the App Store.
Every number shown, nothing hidden
Calculations show their assumptions instead of a single opaque result. Projects and results stay on-device; buying or restoring Premium needs an internet connection, everything else works offline.
Available for iPhone and iPad
KnitMath is now released for iPhone and iPad across 175 App Store territories. Our quilting companion, QuiltMath, is also on the App Store, with free fabric calculators and optional Premium and Extra upgrades.
