Manual and smart-cube timing
Start with a fast manual timer, then connect a supported GAN smart cube when you want move-aware timing and automatic CFOP stage analysis. Both modes keep a clean, repeatable solve loop in the browser.
Direct answer
A useful speedcubing timer should make starting the next solve effortless, preserve accurate session history and turn results into training decisions. SupaKewber combines manual keyboard or touch timing with a separate smart-cube mode, generated 3×3 scrambles, averages, graphs and detailed solve review.
Complete guide
Manual timing is available on almost any modern browser and works with a keyboard or touchscreen. Smart-cube timing uses the cube’s first turn and solved state, removing the reaction time involved in pressing a key or mat.
SupaKewber keeps Manual and Smart Cube results separate. That prevents automatically detected solves from being mixed into manually stopped averages and makes comparisons between sessions easier to interpret.
Choose a mode, follow the generated scramble, ready the timer and solve. The result panel records the time and prepares the next scramble so practice does not stall between attempts.
Recent singles, Ao5, Ao12 and longer averages show short-term form and repeatability. A clickable solve history adds penalties, scramble context and progression instead of leaving you with an isolated number.
When a compatible GAN cube is connected, SupaKewber follows every turn and detects Cross, F2L, OLL and PLL milestones. Individual stage durations can then be compared across the session.
A slower total can still contain a strong Cross or cleaner F2L. Looking at several stage splits helps separate a real improvement from a lucky scramble or a single fast algorithm execution.
Use Manual mode for hardware-neutral practice, stackmat-style routines or devices without Web Bluetooth. Use Smart Cube mode for automatic starts, move-aware review, live cube mirroring and verified online play.
The best mode is the one you can use consistently. Switching is easy, but comparisons should stay within the same timing source when you are judging progress.
Quick answers
Yes. Manual and supported smart-cube practice can be started in the browser without a paid tier.
Manual touch timing works on phones. Smart-cube support depends on whether the mobile browser exposes Web Bluetooth.
SupaKewber uses the cubing.js scramble generator for 3×3 practice.
The Solve Lab includes a csTimer JSON import so existing practice history can be reviewed in SupaKewber.
