About
Carol converts knitting patterns to your gauge and stays with you until the very last round.
YOUR PATTERN, YOUR YARN, YOUR MEASUREMENTS
You found a beautiful pattern, but your yarn is thicker, your gauge is different, or the size doesn't fit. Carol recalculates every number based on real measurements, rounds to valid pattern repeats and shows you honestly how big the difference is in centimetres. No guessing, no calculator, no scraps of paper.
WHAT CAROL CAN DO
Adapt a pattern: Enter the sections of your pattern and Carol converts them to your gauge in six guided steps
Plan a raglan: A top-down raglan sweater, written out round by round with increases, dividing, body and sleeves all the way to the ribbing
Plan socks and hats: Cast-on, heel flap, gusset, toe and wedge crown matched to your gauge and size
Knitting mode: A large round counter with huge tap targets, reminders at exactly the right round and check measurements for try-ons
Gauge library: Saved swatches are ready in every calculator
Share patterns: Designers create patterns directly in Carol and share the file through their own channels. Loading them into Carol is free
Backup: Export all your data as an open file and restore it at any time

KNITTED WITH LOVE IN DENMARK
Carol is written in plain, clear English on purpose, calculates transparently and always shows you where a number comes from. It was born from a real knitting problem: a favourite sweater that needed to be knitted again in thicker yarn.

What's New in Carol
1.2
September 18, 2026
Carol now stays even closer while you knit. In knitting mode, a panel opens your round plan and your pattern with a marker bar, and counters can be edited, count rows and be chained as repeats. New are a knitting dictionary in German, English and Danish that translates abbreviations from other patterns, and a journal with notes and photos for every project. You can search and sort projects and stash, and changing the appearance recolors the app right away.
