Sub10Lab: Cube Timer & Trainer

A practice app for 3×3×3 speedcubing. Timing, algorithm practice, and case recognition training, all in one app. • Every feature is free, with no usage limits or trial period • No ads • No account or sign-in required • Your times and practice records are not sent to Sub10Lab's servers ■ Timer Generate WCA-standard scrambles, then handle inspection, timing, and +2 or DNF penalties on a single screen. You can hide the time while running and keep the screen awake. On devices with a wide enough screen, you can also choose to start by pressing the screen with both hands. ■ Smart Cube Connect a supported smart cube over Bluetooth, and timing starts with your first turn and stops the moment the cube is solved, with Cross, F2L, OLL, and PLL segments recorded. Your scramble progress appears on screen, so you notice a wrong turn right away. From your records, you can see a habits table summarizing pauses and thinking time, how far your cross was from the shortest solution, and the sequence of algorithms you used for OLL and PLL. Your solves show where you tend to stall and what to practice. Supported models: GAN (Gen1–Gen4), MoYu (MY32, MY33, MHC), QiYi, GiiKER, GoCube These features require a smart cube. The timer, statistics, algorithm practice, and recognition drills all work with a regular cube. ■ Smart Timers Connect a GAN Halo Timer Smart over Bluetooth and the time you stop on the timer goes into your records without typing it in. The QiYi Timer Bluetooth Adapter also works; plug it into a compatible timer. ■ Statistics Session-based records, ao5, ao12, mo3, bests, and history charts. You can also add comments to individual solves or delete them. Each weakness explains what is happening and what to practice. ■ Algorithm Practice Includes algorithms for 10 groups: F2L, OLL, PLL, AF2L, COLL, WV, VHLS, VLS, ZBLS, and ZBLL. For each case, pick your algorithm from several candidates, or enter your own with move-notation buttons. Practice with spaced-repetition drills, repeated timing of the cases you choose, the CROSS Trainer, the F2L Trainer, and the Finger Trainer. Practice F2L in time with a metronome to keep a steady pace. ■ Recognition Drills Look at a case diagram and identify which case it is. Choose a spaced-repetition drill, or Time Attack, where you see how many cases you can identify within the time limit. ■ Simplified CFOP Course A mode for people learning the cube for the first time. It narrows things down to five stages—cross, F2L corners, F2L edges, 2-look OLL, and 2-look PLL—and teaches step by step, starting with how to read move notation. ■ More View case diagrams in flat 2D or 3D, and play algorithms in the 3D view. Light and dark themes, a wide-move notation switch (Rw / r), and JSON export and import of all your data. For questions or bug reports, contact support@sub10lab.app.
