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 Start as a guest, or sign in to keep everything in sync. You can delete your account and everything in it from inside the app, at You → Settings → Delete Account. ## Version history (last 2 releases) ### 1.5 — 2026-10-03 CubersDen 1.5: a new Train area for practising one part of the solve, a new way to set up the algorithm trainer, and more smart cubes. TRAIN Learn now has four cards: Solve my cube, the beginner course, Algorithm trainer and Drills. The Algorithm trainer, Drills and the new Playground sit together on one Train screen, with layouts made for iPad. Drills train one part of the solve: • Cross: pick the optimal move count (4 to 8), and after each attempt step through the optimal solution • XCross, Full F2L, Last two pairs, Last pair + last layer • Lookahead: cross and F2L to a metronome, slowly but without stopping; with a smart cube you also get a tempo report • Blocks: the Roux first block, and CMLL recognition Every drill works with or without a smart cube. A session panel shows last, ao5, ao12, best and mean, and "Last time" compares you with your previous day. Algorithm trainer: choose what to practise (sets, categories, your slowest cases or the ones you ticked) and how (recognition or execution, 10, 20, 30 or 50 questions, spaced repetition on or off), then start with one button. Playground: take any scramble, or type or paste your own, solve it and step through the solution move by move. TIMER SOUNDS Two new sounds in Settings, both off until you turn them on. Inspection calls: a voice says "8 seconds" and "12 seconds" during WCA inspection, like a competition judge. Choose a voice, or a plain ding. And a short sound when the solve ends. SMART CUBES XMD Tornado V4 AI and QiYi smart cubes now connect, next to MoYu and GAN. After a smart-cube solve, turn U then U' on the cube to go to the next scramble without touching the screen. "Open the app on" in Settings: start on the Timer, Learn, the Algorithm trainer or Drills. ALSO NEW IN 1.5 • Ghost races: race a real recorded solve by another cuber, turn by turn at their pace. Same scramble, one attempt, and your Elo does not change. In Battles you can also race the pros: real WCA competition attempts by world-class cubers, on the scramble they were solved on. • Your efficiency: in Learn → OLL and PLL, your own cases from smart-cube solves, costliest first, with recognition and execution times. Tick the ones you want and practise exactly those. TPS in Stats and on your profile. • ZBLL in the trainer, and "My algorithm": use your own algorithm for a case. The trainer works with a smart cube and tells you how to set a case up on a real cube. • Links to cubersden.com/s/… open in the app with the replay, and "Try this scramble" races the author's time. Weekly competition, badges and "How CubersDen works". • Sync you can see: when it last synced, Sync now, pull to refresh, live updates. Zen plays rain again. ### 1.4 — 2026-10-02 No release notes. ## More apps by ARVIND JUNEJA OUMM - [Sobienie.pl](https://appshunter.io/ios/app/sobieniepl/id6739706104) - [Vays](https://appshunter.io/ios/app/vays/id6763947081) - [Vays - Markdown reader](https://appshunter.io/ios/app/vays-markdown-reader/id6797046995) - [FoxyDocsy](https://appshunter.io/ios/app/foxydocsy/id6807770444) All apps by ARVIND JUNEJA OUMM: https://appshunter.io/developer/1782767786 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
