Read full description

SewCalc is the sewing calculator your phone should have had from day one. Six focused tools for sewists and quilters who need fast, accurate fabric math -- with results displayed in fractions the way you actually think at the cutting table. NO SUBSCRIPTIONS. NO ADS. NO ACCOUNT REQUIRED. Pay once. Use forever. Your data never leaves your device. --- FABRIC YARDAGE CONVERTER --- Your pattern calls for 2 3/4 yards of 45-inch fabric, but you found the perfect 60-inch wide knit. How much do you actually need? SewCalc tells you instantly: buy 2 1/8 yards. It always rounds UP to the nearest 1/8 yard so you never come up short. Preset bolt widths: 36" | 44/45" | 54" | 58/60" | 72" --- QUILT CALCULATOR --- Enter your finished block size, layout, sashing, and borders. SewCalc calculates yardage for every component: block fabric, sashing, each border, backing (with panel count), and binding strips. One screen, zero guesswork. --- SEAM ALLOWANCE CALCULATOR --- Enter your finished dimensions, pick a seam allowance, and see your cut size instantly. Works in reverse too -- enter cut dimensions to find the finished size. Supports all sides, top/bottom only, or left/right only. Presets: 1/4" (quilting) | 3/8" (knits) | 1/2" (home decor) | 5/8" (garments) | 1" (hems) --- PATTERN RESIZE --- Scale any measurement by percentage (e.g., print at 115%) or between sizes. Enter the original bust measurement and the new bust measurement, and SewCalc scales every piece proportionally. --- ELASTIC CALCULATOR --- Enter your waist measurement, choose your elastic type (woven, knit, or braided), and get the exact cut length including overlap for joining. No more guessing how much to stretch. --- BIAS TAPE CALCULATOR --- Tell SewCalc how wide you want your bias tape and how many inches you need. It calculates the fabric square size and yardage required for continuous bias tape -- the only method that doesn't waste fabric. --- BUILT FOR SEWISTS --- - FRACTION DISPLAY: Results shown as 2 5/8 yd, not 2.625. Because sewists think in fractions. - ALWAYS ROUNDS UP: Every result rounds up to the nearest 1/8 yard so you never run short at the cutting table. - IMPERIAL AND METRIC: Genuine metric presets (90cm, 110cm, 140cm, 150cm bolt widths) -- not lazy inch-to-cm conversions. - REFERENCE TABLES: Built-in guides for bolt widths, seam allowances, and elastic stretch ratios. - OFFLINE: Works without internet. Calculates instantly. Under 1 MB. - PRIVACY: Zero data collection. Zero network calls. Zero analytics. Your sewing calculations stay on your device. --- WHO IS THIS FOR? --- - Quilters planning yardage for their next project - Garment sewists substituting fabric widths from pattern envelopes - Sewists adding seam allowances to pattern pieces - Anyone making bias tape, elastic waistbands, or resizing patterns - Beginners who want confidence at the fabric store cutting counter - Experienced sewists who are tired of doing the math by hand --- ONE PRICE. NO TRICKS. --- $2.99. That is less than a quarter yard of quilting cotton. No subscriptions. No in-app purchases. No ads. No account. No data collection. Just fast, accurate sewing math. SewCalc. The sewing math your phone should have done years ago.
