Purl keeps your patterns, your projects and your yarn in one place. It works the same for knitting and crochet. There is no account to make, and your data stays on your device unless you choose to export it. FOLLOW YOUR PATTERN • Open your PDF patterns, draw on them, highlight and add notes. • Lay a colored band across your row and move it up as you go. It counts the rows for you. • Line up a printed chart, and Purl lights the stitch you are on. • Photograph a paper pattern, and Purl turns the pages into one PDF. • Share PDFs to Purl from Files, Mail, Books or Safari, several at once. • Learning from a video? Watch it from YouTube inside your project, with your counters beside it. DRAW YOUR OWN CHARTS • Color charts: fill in square by square, or start from a photo. • Crochet charts (Beta): draw a line with a finger or an Apple Pencil, and Purl fills it with evenly spaced stitches. Write a round the way a pattern reads, such as "[3 dc, ch 2] 3 times", and Purl draws it. • Knit charts (Beta): knit, purl, decreases and cables on a grid, followed row by row. • Send a chart as a Purl file, and another Purl user can open and edit it. PROJECTS AND STASH • Follow each project from plan to finished, with photos, the yarn and the gauge you actually got. • Note each yarn's color, dye lot and weight, and see how many meters and grams you have. Purl knows about 20 Nordic yarn brands. • Scan a ball band to find a yarn you already have. Purl also spots a new color of a yarn you own. • Find a pattern for a yarn you own, or yarn for a pattern. HANDY TOOLS • A calculator that works out your gauge, spreads increases and decreases evenly, and says how many skeins to buy. • Counters, and knitting and crochet terms in English and Norwegian. • Anything you delete waits 30 days in Recently deleted. • Light and dark mode. On an iPad, your list sits beside what you have open.
