Built around the turn,
not the spacebar.

Hands-free timing

First turn starts it. Solved stops it.

Follow the scramble — tracking is state-based and self-healing, so a wrong turn never derails it. The moment you reach the scrambled state the timer arms; your first turn is t=0.

Cube clocks drift, so cūbrs fits every move’s cube timestamp against your computer’s clock and takes the line — the same technique csTimer pioneered. Your time doesn’t depend on Bluetooth lag.

First turn starts the clock. Solved stops it.

CFOP splits

Every solve, cut into four phases.

cūbrs reads Cross, F2L, OLL, and PLL straight from the cube state as you turn — no taps, no markers, and fully color-neutral. Each phase gets its own time on every solve, so an average that looks fine can still show you a slow OLL hiding underneath.

Phase averages sit next to your ao5 and ao12, and Pro charts each phase over time so you can watch the one you’re drilling actually come down.

Last-layer skip? The phase reads 0.00 — detected, not guessed.

Every solve, split four ways: Cross, F2L, OLL, PLL.

The trainer

Cross 22 · F2L 41 · OLL 57 · PLL 21

Every case with an exact generated diagram — PLL arrows are computed from the actual permutation, not drawn by hand. Star your preferred algorithm per case; drill it timed by move completion, not cube state, so you can rep an alg twenty times without ever re-scrambling.

Wrong turns count as misses. Accuracy is a stat, right next to your ao5.

141 cases, exact generated diagrams, timed by move completion.

Reset & solve

Never hand-scramble back to solved again.

Point cūbrs at any state and it computes a short solution with the bundled min2phase solver — usually around 20 moves. Follow the on-cube guide turn by turn; it heals itself when you misturn, so you can’t get lost.

Want to study a case instead? Snapshot the state, get a solution, and watch it play out on the 3D cube before you touch a piece.
