Cube Solver AI vs FreeCubeSolver

Completely free. No in-app purchases, no subscription, no paid tier, no account — every feature described below is simply there when you open the app. Point your camera at each face and Cube Solver AI reads the colours for you, then walks you through the solution one turn at a time, with the layer actually rotating on screen. SCAN WITH YOUR CAMERA A neural network trained for colour constancy runs entirely on your device, so it copes with warm lamps, cold daylight, and the glare that makes white and yellow look alike. A live overlay shows exactly which colour it reads on every sticker while you hold the cube, so you can see it working before you commit. FIX ANYTHING IT GETS WRONG Detection is never perfect on every cube in every light. Tap any sticker on the 3D cube or the flat net to repaint it, with undo and redo throughout. Stickers the model was unsure about are highlighted, so you know where to look first. SOLUTIONS YOU CAN ACTUALLY FOLLOW Every step names the move, describes it in plain words, and animates the layer swinging on the cube, which is far more useful than a line of notation. Step back and forth freely, jump to any move, or hand it to auto-solve and just watch the cube unscramble itself. Choose slow, normal or fast, and let the camera follow the turning face or stay put. 3x3, 4x4 AND 5x5 The 3x3 uses a two-phase search that finds solutions of around 20 moves. Larger cubes are solved by reduction: centres first, then edge pairing, then the 3x3 finish, including the parity cases that only appear on even cubes. FREE, PRIVATE, OFFLINE The neural network and the solver both run on your iPhone, so your photos never leave the device and nothing is collected about you. It works with no signal at all.

Solve your 3x3 or 2x2 cube in minutes, without paying, without ads and without an internet connection. SCAN YOUR CUBE Photograph each face with the camera or pick photos from your library. FreeCubeSolver reads the colors, checks that the cube is valid and shows which stickers to fix if something was misread. You can also enter the colors by hand. FOLLOW THE SOLUTION The 3x3 is solved in 20 moves or fewer, the 2x2 in the shortest possible number of moves. Each move is animated on a 3D cube with clear notation and a description. Step forward, step back, or let it play at your own speed. LEARN TO SOLVE IT YOURSELF Learn mode teaches the beginner method step by step, with an animated 3D demo of every algorithm. PRACTICE Generate a random scramble, apply it to your cube and solve it, or let the app solve it for you. SPEEDCUBING TIMER Time your solves with a 15-second WCA-style inspection, touch-and-hold start, and +2 and DNF penalties. See your best time and your averages of 5 and 12, with separate sessions for the 3x3 and 2x2. Your times stay on your device.
