Stuck on a twisty puzzle? Point your iPhone or iPad at it. CommuniCube reads every face with the camera, lets you fix any sticker with a tap, and then walks you through the solution one move at a time on an animated 3D model — in plain English, not just notation. Puzzles it solves (all on your device, no internet needed): - 3×3 Cube — a near-optimal solution of about 20 moves, or the Learn mode that solves YOUR cube with the beginner layer-by-layer method so you understand every stage. - 2×2 Pocket Cube — the shortest possible solution, 11 moves or fewer. - 4×4 and 5×5 cubes — solved step by step by reduction: centres, then edges, then finish like a 3×3, with parity handled for you. - Pyraminx — optimal, 11 layer turns or fewer plus up to four tip turns. Skewb — optimal in 11 moves or fewer. - Ivy Cube — optimal, 8 moves or fewer. Dino Cube — solved one edge at a time. - Tower 2×2×3 and Domino 2×3×3 cuboids — optimal within their own moves. - Megaminx and Kilominx — the twelve-sided puzzles, solved piece by piece with sequences that move only three pieces at a time. - Mirror Cube (entered by block depth) and Void Cube. Scanning that just works: - Guided capture of each face with a live overlay showing what the camera reads; it snaps automatically when the picture is steady. - Colours are worked out from all the faces together, so warm lamps and shadows don't fool it. - A check screen shows the whole puzzle as an unfolded net. Tap any sticker to recolour it, and if the pattern is impossible the app tells you exactly why: wrong sticker counts, a piece that can't exist, or a corner that was reassembled twisted. Follow along with confidence: - Every move is written out plainly ("Turn the right face up, away from you") beside a 3D model with a direction arrow, and the standard notation if you want it. - Play, pause, step back and forth, change the speed, and jump between stages on the big cubes. - Hands full? Turn on "Read each move aloud" and CommuniCube speaks every move, in the solution and in the Learn lessons; tap the move card for the next one. - Timer with scrambles for thirteen of the puzzles — random-state on the 3×3 and the Void Cube, random-move on the rest — plus inspection, ao5/ao12 and a chart of your times. - A Learn tab with animated notation for twelve of the puzzles and the full beginner method. - Colour themes and a colour-blind mode that puts a letter on every sticker.
