Cubist is a beautifully designed cubing app where you learn, time, and compete — built to WCA standards, for the phone. Most cube timers just count. Cubist takes you from your very first solve to a spot on the global leaderboard, in one app you'll enjoy opening. FOUR PUZZLES — ALL FREE 3x3, 2x2, Pyraminx, and Skewb, each with its own scrambles, records, and leaderboards. No puzzle sits behind the paywall, and every one of them has a beginner's path. More official WCA events arrive in free updates, and your records and unlock carry straight over. LEARN TO SOLVE — FREE New to a puzzle? Step-by-step tutorials walk you through your first solve of each one: Layer-by-Layer for the 3x3 and the 2x2, Top-Down for the Pyraminx, Sarah's Beginner for the Skewb. The puzzle renders right in the app, highlights the next move, and shows the exact turns — so you learn by doing, not by pausing a blurry video. Every beginner method is free, forever, on all four puzzles. Faster methods — CFOP, CLL, EG-1, Keyhole, L4E, Sarah's Advanced — are part of Cubist Lifetime. A WCA-GRADE TIMER This is the timer serious cubers expect. Real 15-second inspection with +2 and DNF applied at the official boundaries. Centisecond precision down to 0.01. ao5 and ao12 calculated the WCA way, with best and worst solves trimmed exactly as they should be. Random-state scrambles, generated the way official competitions do and served fresh for every solve. Free accounts get 5 timed solves a day, shared across all four puzzles — enough for a full ao5 every day. Cubist Lifetime times as many solves as you want, every day, on every puzzle. COMPETE — GLOBAL, REGIONAL, FRIENDS — FREE Cubist is a competition platform, not just a stopwatch. Climb per-puzzle leaderboards filtered by the whole world, your country, your continent, or just your friends. Every ranked solve is server-verified, so a place on the board actually means something — no fake times, no padded averages. Add friends by username or invite QR and put your averages head to head. TRACK YOUR PROGRESS — FREE Personal bests for single, ao5, ao12, and mean, plus your full solve history — synced to the cloud for free so they follow you to any device. Cloud sync is never paywalled — it's what puts you on the leaderboard. GO FURTHER WITH CUBIST LIFETIME Ready to break into CFOP and chase sub-X?
