What Tricolab does
Hands-free counter
One very big + button, a screen that stays on, and your voice: say "next" or "back" without putting your needles down.
A pattern that keeps your place
Import a PDF, photograph a paper pattern or paste its text. Your current line is highlighted and abbreviations are explained in plain words.
36 original patterns
Six styles: Classic, Modern, Rustic, Emoticon, Crop circle and Clothing. A drawing of the finished item, a measured schematic and sizes that recalculate the instructions.
Motif generator
30 chart motifs — crop circles, fishing, construction, leaves, racing, knight — in your size and colours, with the rows written out automatically.
The Lab
Step-by-step techniques, materials, chart examples, an abbreviation dictionary and calculators for gauge, sizing and yarn.
Share and stay motivated
A finished-project card to share, a monthly challenge, badges and your year in review.
Clothing, from S to 2XL
Sweater, hooded cardigan, jacket, sleeveless vest, skirt, headrest cover and car seat pad, with optional body fit.
Your piece in 3D and augmented reality
See it at real size on your table or wall. While you knit, finished rows show in colour and the rest faded.
Magazine-style export
Turn a finished project into a magazine cover: big headline, pattern, yarn, time, rows and a QR code, ready to share.
