Plan your next knit with clear numbers and less guesswork. KnitMath turns your swatch gauge into cast-on stitches and rows, estimates the yarn you need and keeps your project details together on your iPhone or iPad. START WITH YOUR SWATCH • Calculate stitches and rows for scarves, cowls, hats and blankets. • Work in centimetres or inches. • Fit stitch counts to a pattern repeat, including edge stitches and your choice of rounding. • See the resulting measurements and calculation assumptions. KEEP YOUR PLACE • Count rows or rounds with large, simple controls. • Resume your current draft and counter after closing the app. • Save one project for free, including yarn, needle and project notes. • Look up metric, US and UK needle and crochet-hook sizes. GO FURTHER WITH PREMIUM One optional, one-time purchase unlocks: • Yardage, whole-skein quantities and leftover estimates from a weighed swatch or known length. • Yarn substitution estimates. • Even increase and decrease spacing for knitting, using kfb and k2tog instructions. • A handmade price draft with yarn, labour, extras and markup in EUR, USD or GBP. • Unlimited saved projects, shareable result cards and PDF project summaries. Calculations and projects stay on your device. No app account, ads or tracking SDKs. An internet connection is needed for App Store product information, purchases and restoration. KnitMath provides planning estimates, not complete knitting patterns. Check your swatch and finished measurements. Yarn substitutions still need a fresh gauge check; price drafts are not invoices or tax advice.
