LetCube
Read full descriptionHide full description
LetCube turns cube solving into a visual learning game that children can understand and follow. A matching 3D cube shows every change. Instead of memorizing formulas first, kids learn by turning, observing, checking, and correcting. A wrong turn is not failure - LetCube keeps collecting clues and always offers another useful step. QUICK SCAN OR MANUAL INPUT Photograph the six faces in numbered order and LetCube recognizes the whole cube. Every face can be reviewed, retaken, or fixed with a tap. The complete 3x3x6 color editor is always available when the camera is not. STEP-BY-STEP 3D GUIDANCE Every step is a real, gentle turn of the 3D cube with friendly arrows on the moving layer - no cryptic notation to decode. Play or pause, step back, step forward, at a pace you choose. Reduce Motion replaces animated effects with clear static guidance. CUBE ACADEMY No cube at hand? Swipe the 3D cube: the layer follows your finger and snaps into place. Start with small lessons, then solve scrambled cubes, beat the clock, and play freely. Every finished round earns stars and points - full stars for solving alone, and stars are always earned even with hints. Levels grow with practice, so children can see their own progress. A Circle Map lays the cube's 54 stickers flat on the crossings of nine circles; turn a layer and the stickers on that ring slide along with it, so kids see the 3D cube and the flattened whole at once. KID-FRIENDLY THEMES Choose classic colors, animals, or fruits. Themes change only the display - not cube recognition or solving. Narration, sound effects, and guide speed are adjustable. FOR GROWN-UPS - Completely free and ad-free - No data collected; scanning, solving, and progress all work fully offline - Camera images are processed only on-device, never saved or uploaded, and discarded immediately - Settings and outbound links are protected by a grown-up multiplication gate - An optional tip jar in the parent area is handled by Apple and unlocks nothing From exploration and observation to a solved cube: pick it up, follow along, and learn.
