Rowtine is a knitting and crochet app. It keeps in one place what is usually scattered across a project: yarn stash, PDF patterns, row counters and project notes. Features: * Track every project from cast-on to finished piece. Between sessions the app remembers where you left off. * Import a PDF pattern: sections, rows and sizes are rebuilt automatically, entirely on the device. Patterns in English, French, German and Spanish are supported. * Read a pattern with a size selector: every number in the text is filtered down to the chosen size. * Follow a chart row by row, with a movable marker and an abbreviations sheet always at hand. On a tablet, the chart and the text can be shown side by side. * Manage a yarn stash: what is reserved for a project, what is still free, with a warning when there isn't enough left to finish a piece, including multicoloured yarns (gradient, self-striping, speckled, hand-dyed). * Track the cost of every project; purchases and gifts are recorded separately. * Look up a needle or hook size from a yarn's ball band and a pattern's gauge. * Two standalone tools: an increase/decrease distribution calculator and a free-standing counter. * Metric or imperial units, five currencies. * Interface, in-app guide and pattern import in English, French, German and Spanish. The app works offline and keeps all data on the device: no account, no data collection, no server.
