CubersDen vs CubeSensei

Got a Rubik's cube that's been sitting scrambled in a drawer for months? We'll show you how to solve it, step by step, on your very own cube. And once you've done it, the real fun starts, because every day you'll get a little bit faster. Best of all, everything in CubersDen is free. There's no subscription, no ads and no paid levels, and every feature you read about below is there for everyone. FIRST, SOLVE IT FOR THE FIRST TIME Show your cube to the camera or paint the colours in with your finger, and CubersDen walks you home from exactly where your cube is right now. We split the beginner method into eight steps. Each one is explained in plain words first, then shown on a 3D cube you can spin around, and then you practise it on the cube on screen or on your real one. Stuck? We'll tell you where to look. It all works offline too. THEN A LITTLE FASTER EVERY DAY The timer has WCA-style inspection, +2 and DNF penalties and scrambles for eleven events, and your stats show how you're improving: averages of 5, 12 and 100, personal bests and charts. The new daily streak keeps a cube in your hands every day. Your flame grows with each day, a week in a row earns you a rest day that saves your streak on its own, and when today is still empty, your phone gives you a nudge. SMART CUBES, A COACH AND ALGORITHMS Got a GAN, MoYu or QiYi smart cube? Connect it over Bluetooth and the timer starts with your first turn and stops the moment the cube is solved. Every one of those solves goes to the coach on cubersden.com, which looks through your recent solves and tells you straight what costs you the most time: a long cross, pauses between F2L pairs, or a PLL you still do in two steps. It also tells you which algorithm to learn next to win back the most seconds. The algorithm trainer in the app has all 57 OLL cases, all 21 PLLs and the F2L cases, and it schedules your reviews so each algorithm comes back just as it starts slipping from memory. EVEN BETTER WITH OTHERS Every week there's a competition with the same scrambles for everyone. You can play a 1v1 battle, open a room for your friends, or race the ghost of your own best solve. And when you fancy something completely different, fire up Rush, a game of quick moves against the clock. THE SAME CUBE EVERYWHERE Your solves, streaks and progress are the same on iPhone, iPad, Apple Watch, Apple TV and cubersden.com. The app speaks English and eight other languages, and it's free with no ads. Start as a guest and make an account later if you like. You can delete your account and everything in it from inside the app: You → Settings → Delete Account.

Learn something from every solve. CubeSensei turns your Bluetooth smart cube into a coach. Every turn is read straight from the cube, so each solve is broken down move by move — cross, F2L, OLL and PLL — with recognition and execution timed separately. CONNECT YOUR CUBE Works with GAN, MoYu and X-Man smart cubes over Bluetooth. The app remembers the cube you used last and reconnects to it on its own, so you can pick it up and start turning. SEE WHERE THE TIME GOES • Stage splits for every solve, with recognition vs. execution timing • Automatic case and algorithm detection • Replay any solve, move by move, in 3D • Cross analysis showing the solution you could have used • Visual aids for every stage, plus "take me there" to set your cube to any position FIND YOUR WEAK CASES • Per-case charts for time, frequency and turns per second • Sortable tables that rank your slowest and least consistent cases • Spot the cases that are slow, frequent, or wildly inconsistent TRAIN THE RIGHT THINGS • Training Planner — a plan built around the cases costing you time • Algorithm Trainer — drill F2L, OLL and PLL with spaced repetition • Cross Trainer — practice efficient crosses and compare with the optimal one • Algorithm Library — the complete F2L, OLL and PLL lists, plus notation • Solve Helper — step-by-step guidance from any scramble KEEP TURNING Daily and weekly challenges, personal records and statistics that show progress over months, not just today. WORKS OFFLINE Once you are signed in, solving runs on the device. Connect a cube, time a solve and see it broken down with no connection at all. Solves are stored on the device and sync when you are back online; browsing your history needs a connection. A Bluetooth smart cube is required. Every turn CubeSensei times and analyzes is read from the cube, so the timer, the training modes and the analysis need one. Without a cube you can still browse the algorithm library and replay solves you have already recorded. Case charts and statistics are on iPad. Archive, statistics and history-based suggestions need a connection.
