About
Built by people who kept reaching for the spacebar.
cubrs started with a simple annoyance: you have a cube that knows exactly when you turned it, and you’re still hitting a key to start a stopwatch.
Why we built it
Smart cubes stream every turn with a timestamp. That’s enough to time a solve precisely, split it into CFOP phases, and replay it move by move — no spacebar, no stackmat, no arguing about when the clock started. Once you have that, comparing times stops being “compare screenshots” and becomes something you can check: every turn is on the record.
So we built the timer we wanted, then kept going: a trainer that drills 365 cases across 7 methods by move completion, honest support for the smart cubes people actually own, and now friends and leaderboards that count only checked smart-cube solves.
What we believe
Timing should come from the cube, not the keyboard. The free tier should be a real product, not a trap. There are no ads and we don’t sell your data. A paid Pro plan is planned to keep the lights on. And when a cube is only half-supported, we say so.
