自由拼豆

Turn favorite pictures into fuse-bead patterns and build real artwork bead by bead, following color codes

Design Philosophy

Let algorithms handle the mechanical work — drawing grids, matching colors, counting beads — and leave the joy of placing each bead to you. Pick a picture and everything else happens automatically, entirely on your device; pictures never leave it.

Core Features

• One picture, an instant pattern

  Pick a picture from your photo library (or use a built-in sample) and it converts automatically into a fuse-bead pattern with color codes. Tall portraits and wide shots are fitted proportionally without cropping — the pattern matches the original picture.

• Five conversion modes, side by side

  Classic Cartoon (clean hard-edged color blocks), Photo Natural (error-diffusion dithering), Pattern Stable (reproducible ordered texture), HD Detail (two-stage scaling), Precise Color (CIEDE2000 perceptual color difference). Cartoons, photos and patterns each have a best fit; compare all five on one screen and pick with one tap.

• MARD standard palette system

  Built-in MARD tiered sets: 24 trial / 36 starter / 48 beginner / 72 intermediate / 96 advanced / 120 flagship / 221 full color, each tier contained in the next, so the palette matches the beads you actually own. The 221 solid colors are organized into nine color families, each with its own name. Custom palettes can be picked by family, named and saved — or generate patterns using only the colors you have on hand.

• Any board size you like

  Three standard square boards of 25 / 50 / 100, or a custom 5–200 edge length — up to 200×200 (40,000 slots) — for everything from small keychains to large wall pieces.

• A helper for the assembly process

  Numbered row/column rulers for precise positioning, with 10×10 bold-region outlines. Tap a slot to cycle "to place → placing → done" and track exactly where you are; select by color code to advance a whole color at a time, with undo and redo at any point.

• Export, print and shopping lists

  One-tap PNG export with row/column rulers and bold region lines, ready for print or screen casting while you build; per-color usage is counted automatically into a shopping list, so you buy exactly the beads you need.

More Features

• Fully offline

  The app has no networking capability. Conversion, assembly tracking and export all happen on your device; pictures are never uploaded or shared. Works and palette data stay in the local app directory and are removed on uninstall.

• Clean interface

  A focused, distraction-free interface designed for the task at hand.
