CubersDen: Cube Timer & Solver

You followed a video, got lost, and now you are holding a cube you cannot solve. That is exactly where CubersDen starts.

BRING US YOUR MESSED-UP CUBE
• Point your camera at the cube and CubersDen reads the six faces, one at a time — each one captures itself as soon as you hold the cube still
• You check each face as it is read, and fix any colour with a tap
• Or paint the colours in by hand — the fallback that always works, and needs no camera at all
• Then choose: fix it fast, or be taught while you fix it
• "Teach me" walks you home from the state your cube is actually in — not from a solved cube, not from a scramble the app chose

LEARN TO SOLVE, IN EIGHT STEPS
• The beginner method broken into eight steps, from the daisy to the last yellow corner
• Each step explains the idea in plain words, then shows a narrated 3D demo you can scrub, pause and replay
• Then you practise on a cube on screen: turn it with your finger, and the app knows the moment you have the step right
• A hint ladder for when you are stuck — a nudge, then where to look, then the moves
• Holding a real cube instead? CubersDen dictates the moves one at a time, then shows you what your cube should look like and asks whether it matches. Say it does not and it walks the moves back with you, one at a time.

IT ALL WORKS OFF THE GRID
• The colours are read on your phone, the solver runs on your phone, and all eight steps are built into the app — scan and solve in aeroplane mode
• The camera is on only while a scan is open. No photo is written, no video is recorded, and no image ever leaves the device

PRECISION TIMER
• Hold-to-start timing, accurate to the millisecond
• WCA-style 15-second inspection with +2 and DNF penalties
• Scrambles for 11 WCA puzzles, each drawn as a cube diagram
• Light (Mat) and dark (Carbon) designs, and a distraction-free Zen mode

SESSIONS AND STATISTICS
• Ao5, Ao12 and longer averages, mean, best and worst single, standard deviation, DNF and +2 rates
• Trend, histogram and distribution charts, and CSV export

ALGORITHM TRAINER
• All 57 OLL cases, all 21 PLL cases and F2L, each with a diagram
• Recognition and execution drills, scheduled by spaced repetition

FRIENDLY BATTLES AND COMMUNITY
• Race another cuber head to head: quick match, invite, or join by code
• Follow other cubers, post solves, comment and share scrambles
• Report and block tools on every post, comment and profile
• Community features are off for accounts under 13; timing, statistics, the beginner course and invite battles still work

PHONES AND TABLETS
• One app for both — the scanner, the eight steps, your sessions, statistics and trainer progress are the same on each, and follow you across devices when you sign in
