Never solved a cube?
Start tonight.
Learning to solve is free.
Your smart cube walks you through your first solve.
Connect a Bluetooth smart cube and cubrs reads every turn. From wherever your cube is right now, it tells you the next piece to place — in plain color language, with the exact moves — and heals itself when you turn the wrong way. No memorizing, no diagrams to decode. You follow along, turn by turn, until the cube is solved.
I have a smart cube
Open cubrs on a desktop Chrome, Edge, or Opera browser and start the guided solve. It’s free.

cubrs needs a desktop browser to reach your cube over Bluetooth. Send yourself the link and a short start guide for when you’re at a computer.
Don’t have a smart cube yet? A smart cube is the cube that teaches you — here’s the buying guide and how to pick one.
The journey
From your first solve to your fastest.
The same app that teaches you to solve is the one that makes you fast. Four steps, one cube.
Your first solve, today
The guided solve looks at your actual cube and names the next move in colors you can see: “bring the white-red edge up to the top.” Follow the turns to a solved cube. This part is free, forever.
Understand the method
A short beginner tutorial teaches the layer-by-layer method behind those moves, plus an interactive lesson on cube notation — what R, U, and a little tick mark actually mean. You go from following steps to understanding them.
Build real speed
When you’re ready to get quick, the trainer drills all 141 CFOP cases with exact diagrams, and every solve is split into Cross, F2L, OLL, and PLL so you can see which phase is holding you back.
Compare with friends
Add friends with a code and see how your times compare. Leaderboards and six skill divisions show where you stand, counting only checked smart-cube solves.
Before you start
The honest answers.
Yes — a Bluetooth smart cube, which has a motion sensor inside so the app can see every turn. A regular cube won’t connect. Our buying guide picks safe ones at three budgets, and the supported list shows exactly what works.
The guided solve walks you through it turn by turn, at your own pace, from whatever state your cube is in. You don’t need to know any moves or memorize anything to start — that’s the whole point of guided.
Nothing today. The guided first solve, the beginner tutorial, the notation lessons and the full trainer are all free. A paid Pro plan is planned but not on sale yet; the pricing page has the details.
Not for the guided solve — talking to a cube over Bluetooth needs desktop Chrome, Edge, or Opera. On a phone, send yourself the link above and pick it up at a computer.
cubrs is new, so we’re not going to invent testimonials. Once real people have learned their first solve here, this is where their words go. Until then, the only promise we’ll make is the honest one: the app walks you through it, turn by turn.
