About this app

Practice your 3-Style algs for 3x3 blindfolded cubing, wherever you are.

Pick a set, hold to time, and drill until every case is under your target. Or pair a Bluetooth smart cube and let the trainer do the timing for you.

SMART CUBE SUPPORT
Pair a smart cube and the timer runs itself: each case starts on your first turn and stops the instant the alg lands. No holding, no tapping.
• Recognition and execution are timed apart, so you can see whether it is your memo or your fingers
• Execute the wrong alg and it names the pair you actually did
• Every mistake is remembered per case, and becomes a drill of its own
• Replay the exact moves the cube saw, to find where an alg went wrong
Works with MoYu, GAN, QiYi, GoCube / Rubik's Connected and Giiker cubes.

PRACTICE MODES
• Sets — pick the sets you want and run the whole pool, optionally repeating until every case is under target
• Race — drill random letter pairs for a fixed number of minutes
• Slowest — drill your slowest cases, or the ones you fail most
• Pairs — the letter pair list for a set, with no timer

EVERY CASE TYPE
Corners, edges, 2-flips, 2-twists and parity, plus custom sets of your own algs.

STATS THAT POINT SOMEWHERE
Per-case solve counts, best and worst, and averages coloured against your own distribution. Filter by type and period, sort by any column, and open a case for its full history. Your slowest and most failed cases feed straight back into practice.

MAKE IT YOURS
Your own 24-letter schemes for corners and edges, your own buffers, and the orientation you actually hold. Three themes. Export and import your times and custom sets as a file.

Everything stays on your device. No account, no ads, no tracking.

What’s new

Smart-cubes bug fixing:

- Cases could get stuck. They should now always complete properly
- Parity now works with any buffer setup. Completion demanded one specific edge swap, so parity refused to drive at all for some buffer combinations. Any rigid swap of two edges is now accepted, matching how solvers actually execute it.
- "Show next alg" is honoured in smartcube-driven runs. Setting was previously ignored for smart cubes
