About

CubeDojo

Read full description

CubeDojo is a speedcubing app for the whole way: from your very first solve to full CFOP, with a competition timer that keeps every time you do. TIMER • All 17 WCA events, each with a random-state scramble like the ones used in competition, and a picture of it • 15-second inspection with warnings at 8 and 12 seconds, and +2 and DNF counted the way competitions count them • Ao5, Ao12, Ao100 and more, mean, best, histogram, trend and personal bests • Sessions, splits and a round simulator with cutoffs and time limits • Bring your times from csTimer or Twisty Timer, and export them whenever you like LEARN • A step-by-step path: notation, the beginner's method layer by layer, the 2-look last layer, then full F2L, OLL and PLL • Every move animated in 3D at the speed you choose: play, pause, step forward and back • Do it on your cube or on the virtual one, then a quick recognition quiz TRAIN • OLL, PLL, F2L (every slot) and 2-look trainers • Train one case, the ones you pick, the ones you know, the ones you are learning or the slowest • Random-state scrambles with the case fixed: never the inverse of the algorithm, so you learn to recognise the case, not the scramble • Review what you know: when you forget a case, CubeDojo shows it again with its fingertricks and has you solve it several times in a row until it sticks • Spaced repetition picks what to review each day, and the statistics show which cases you forget and which ones you have mastered ALGORITHMS • Every case with its diagram, its 3D animation and several algorithms to choose from • Write your own: CubeDojo checks it and tells you when it is backwards, mirrored or solves a different case • See how cases relate: Ua and Ub are each other's inverse, Ja and Jb are mirror images SOLVE • Paint your scrambled cube and get the solution, or a guided beginner's solve linked to the lessons • If the colours cannot be a real cube, it tells you which sticker is wrong PROGRESS • Streaks, levels, achievements, goals and how far you are through every set Sign in with Apple or Google, and your times, algorithms and progress follow you to every device and to cubedojo.app. CubeDojo is free with ads, and they never interrupt practice: at most one full-screen ad a day, when you start a lesson or a training mode, never the first time that day, and none on your first day. Nothing ever shows in the timer, inspection, drills, reviews or lessons. An optional one-time purchase removes every ad for good. CubeDojo is not affiliated with the World Cube Association.

Verdict

The call
