StitchTap keeps count for you while you knit, so you don't have to hold the numbers in your head. Count rounds, rows, pattern repeats, decreases and increases โ€“ anything you need to keep track of. Tap to count up, swipe between counters, and keep several going at once. SIMPLE COUNTING A big, clear counter you can hit without looking down. Tap to increase. Press and hold to name a counter โ€“ "rounds", "decrease every 4th", whatever you like. MULTIPLE COUNTERS Swipe between as many counters as you like. Count the main piece in one, the pattern repeat in another, and your decreases in a third โ€“ all at once. PROJECTS Group your counters into projects so you always come back to exactly where you left off โ€“ one project for the sweater, one for the socks. APPLE WATCH Count straight from your wrist. Counters sync between watch and phone, so you can switch freely. With Always-On display, the number stays visible even when the screen dims. MADE FOR KNITTING Keep the screen awake while you work. Choose a light or dark theme. Switch between six languages: English, Norwegian, Danish, Swedish, German, and French. StitchTap is part of the KniTime family, alongside StitchEven and YarnSwap. Made for knitters, by a knitter.
