Your cube is the timer.
cūbrs connects to your Bluetooth smart cube. The first turn starts the clock. The solved state stops it. No spacebar, no stackmat, no argument.

How it works
Scramble. Solve. It’s already recorded.
01
Follow the scramble
The app watches every turn. Wrong move? Undo it — tracking self-heals.
02
Solve
Your first turn is t=0. Timing comes from the cube’s own clock, fitted move-by-move — the same technique csTimer uses for smart cubes.
03
It’s saved
Time, moves, TPS, and your CFOP splits, recorded the instant the last piece lands.
Analytics
Know where the time goes.
cūbrs detects your Cross, F2L, OLL, and PLL from the cube state itself — color-neutral, zero setup, on every solve. Averages per phase tell you what to train next.
OLL skip? It shows 0.00. We saw it too.
Cube-clock timing, fitted move by move.
Train
365 cases. Drilled the way you actually turn.
The full CFOP library — Cross, F2L, OLL, PLL — plus decks for the beginner method, Roux, ZZ, Petrus, blindfolded and one-handed. Exact diagrams and timing by move completion, not cube state. Repeat an alg twenty times without resetting; every rep gets a time, every wrong turn counts against your accuracy.

New to the cube?
Never solved a cube? Start here.
You don’t need to know a single move. Connect a smart cube and the guided solve walks you through your first solve turn by turn, naming the next piece in plain colors — then the same app makes you fast. Learning to solve is free.
Learn to solve — start hereFriends and leaderboards
Compare times with real people.
Add friends with a short code and see how your times stack up. Public leaderboards rank the best average of 5 by day, week, month, year and all time, and only count smart-cube solves the server has checked turn by turn. A board stays closed until 25 players are on it, so it never shows a handful of names.
How friends and boards work#Solverao5
The world board opens when 25 players have verified times this week. Until then there is nothing to rank, so nothing is shown.
