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 iPhone, the solver runs on your iPhone, 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 the photo library is never touched

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

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

SMART CUBE, SMART TIMER AND APPLE WATCH • Connect a GAN Gen2 or MoYu WeiLong V10 AI smart cube over Bluetooth and let your own turns start and stop the timer • Connect a GAN Smart Timer and time on the pads • Scramble and time on your wrist, with haptics through inspection; solves land back on your iPhone

ONE APP FOR IPHONE AND IPAD • Universal — the scanner, the eight steps, your sessions, statistics and trainer progress are the same on both, and follow you across devices when you sign in
