Qubo is a speedcubing timer that stays out of the way. Long-press to ready it, release to start, then tap anywhere on the screen to stop — no aiming for a small button while the clock is running. COMPETITION SCRAMBLES Scrambles for 3×3, 2×2 and Pyraminx are drawn at random from every state the puzzle can reach — the same standard used at official competitions. 4×4 and Windmill get random-move scrambles with redundant turns filtered out. Tap the scramble to see it as a full sequence of moves. SESSION STATS See how a practice run actually went: your personal best, a trend line across the session, and Ao5 and Ao12 averages for each puzzle. Every solve is kept with the scramble it was given and any +2 or DNF, stored on your device. PERSONAL BESTS Each puzzle tracks its own record, and your bests follow you across devices through iCloud. New records get the celebration they deserve. PUZZLES 3×3 is free, always. 2×2, 4×4, Windmill and Pyraminx each unlock with a one-time purchase — no subscriptions, ever. Curious about a locked puzzle? Watch a short video to earn free solves and try it before you buy. Whether you're learning your first algorithm or chasing sub-10, Qubo gives you competition-grade timing without the clutter.
