A smart cube timer for serious cubers
A stopwatch gives you one number. A smart cube gives you all 62 moves, every pause, and exactly how long your Cross, F2L, OLL and PLL Takes. Connect one and find out what you need to practice!
Works in Chrome, Edge and Opera, on desktop and Android.

Features
Timing is the least interesting part
Your solve stops being one number and becomes something you can actually take apart.
Every single move
Every quarter turn, timed to the millisecond. Move count and turns per second come straight out of it.
Phase splits
Cross, F2L, OLL and PLL, read from the cube state rather than guessed. See exactly where your seconds go.
Every pause, marked
A long gap between moves is recognition, not execution. Now you know whether to fix your lookahead or your hands.
Full 3D replay
Watch the solve back at any speed or step through it move by move. Gyro cubes even replay at the angle you actually held.
Mistakes, pointed out
Four moves cancelled before OLL. A cross solved in twelve moves that only needed eight. Flagged on the timeline exactly where it happened.
Saved forever
Every reconstruction is stored with its solve, so something you did on the laptop in March still replays on your phone today.
Compatibility

FAQ
Smart cube questions
Which browsers support a Bluetooth smart cube?
Chrome, Edge and Opera, on Windows, macOS, Linux, ChromeOS and Android. Safari and Firefox do not ship Web Bluetooth yet, so iPhone and iPad need one of the browsers that does. Everything else in Flowtimer works anywhere.
Which smart cubes does Flowtimer support?
Tested and confirmed: the GAN i Carry 4, i4 and 16 UI FreePlay, the MoYu V10 AI and V11 AI, and the QiYi QY SC-S. Flowtimer also speaks the GAN Gen1 to Gen4, MoYu, QiYi, GoCube, Giiker and HEYKUBE protocols, so other cubes in those families should work too. Ask on Discord if yours does not.
Do I need an app or the cube maker's software?
No. You pair straight from the browser, so there is nothing to install and no extra account to make.
What happens when Bluetooth drops a move?
Flowtimer compares its own idea of the cube against what the cube reports and puts the missing turns back. If a gap really cannot be recovered it gets labelled, so you are never looking at a reconstruction that is quietly wrong.
Can I still use a keyboard or a Stackmat?
Of course. Space bar, touch and Stackmat all keep working, and you can switch whenever you like.
Does the timer start automatically?
Yes. Once your cube matches the scramble, your first turn starts the clock and solving it stops the clock. No key press at either end.
Are smart cube solves saved?
The whole move stream is stored with the solve, so your reconstruction and replay are there on every device you sign in on.
Connect your cube and do one solve
The full reconstruction is waiting before you have even put the cube down.
