Your sewing companion, finally built right
Introducing the Quilt Math App.
Ever wish you had a single app that did all the math so you could get back to sewing? That's exactly why this one exists—I built it to be the tool I wanted, and I'm sharing it in case it helps you too.
Inside you'll find 30 tools and calculators covering everything from quilting to garment work, and 27 of them are completely free—so is the app itself, no catch.
A few favorites:
Your calculations talk to each other. Run the sashing calculator, send the results straight to the border calculator, then backing/batting, then binding. No re-measuring, no re-typing, no mistakes.
Making a t-shirt quilt? The built-in calculator tells you exactly how much interfacing to buy.
Stuck mid-project? Troubleshooting guides walk you through common machine issues by type.
Never lose a calculation. history keeps track of your recent work—your last 3 free, unlimited with a small monthly or yearly subscription. Subscribers can also group calculations into saved projects, build shopping lists, and sync everything across all their devices.
And for the color nerds: three premium conversion tools find the closest real match (not just a nearby swatch) between thread brands, solid fabric brands, and perle cotton colors—so you can substitute with confidence.
Whether you stick with the free tools or unlock the extras, this app is built to make your next project faster, easier, and a lot less mathy.
You can find the app in the Apple App Store, Google Play Store or at www.QuiltMath.app!
