Cube is the precision speedcubing timer built for cubers who care about improvement. Time every solve with millisecond accuracy, track rolling averages as they drop week over week, and celebrate every personal best with the scramble and moment preserved. MILLISECOND-PRECISION TIMER Hold to start, tap to stop. Zero-latency timing that matches competition feel. Large, monospaced display designed for glanceable reads mid-session. The timer is the entire app - everything else supports this screen. SCRAMBLE GENERATOR Randomized scrambles for 3x3 and 8 additional puzzle types (2x2, 4x4, 5x5, Pyraminx, Megaminx, Skewb, Square-1, One-Handed). Every scramble is written in standard WCA notation, so it reads exactly like the ones you get at a competition. AUTOMATIC AVERAGES Your ao5 and ao12 update in real time as you solve. Rolling averages are the language of speedcubing - "I'm sub-16" means your average, not your best single. Cube speaks that language natively. PERSONAL BEST TRACKING Every PB is a milestone. Cube detects new personal bests automatically, preserves the scramble, and marks the solve so you can revisit your greatest moments. Track your best single plus your best ao5 and ao12 across every puzzle type. SESSION MANAGEMENT Organize your practice into sessions. See your session mean, best ao5, best ao12, solve count, and best single at a glance. Every session tells the story of a practice set. ALGORITHM LIBRARY The complete reference: all 57 OLL cases, all 21 PLL cases, and all 41 F2L cases in standard notation. Every algorithm you need for CFOP, grouped by case type and always in your pocket. MULTI-PUZZLE SUPPORT (Pro) Unlock timing for 2x2, 4x4, 5x5, One-Handed, Pyraminx, Megaminx, Skewb, and Square-1. Each puzzle gets its own scrambles, dedicated statistics, and independent personal best tracking. New puzzle types included free in future updates. BUILT FOR FOCUS Dark-first interface with pure black backgrounds and monospaced timing display. No distractions during solves. No social feeds. No gamification gimmicks. Just you, the cube, and the clock. iCLOUD SYNC Your solve history syncs automatically across all your devices via iCloud. Thousands of solves spanning months of practice, always safe and always accessible. FREE FEATURES - Unlimited 3x3 solves with millisecond precision - Randomized 3x3 scramble generation - Automatic ao5 and ao12 calculation - Personal best tracking (best single, best ao5, best ao12) - Session management - Full solve history - Complete OLL, PLL and F2L algorithm reference (view) CUBE PRO - All puzzle types (2x2, 4x4, 5x5, OH, Pyraminx, Megaminx, Skewb, Square-1) - Per-puzzle scramble generation - Per-puzzle statistics and averages - Per-puzzle personal bests - Future puzzle types included free Whether you just broke sub-60 for the first time or you are chasing sub-10, Cube gives you the data to prove you are improving. Every solve counts. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
