What is Speedcube?

Speedcube is a browser-based timer for Rubik's Cube solves, built for cubers who want a straightforward way to time and track their attempts. The site is a web application, so it runs in your browser rather than as an installed desktop program or mobile app.

What it does

The core function is timing solves, the same job a stopwatch or stackmat timer does at a competition. A typical session looks like this: you scramble the cube, start the timer, solve, and stop it. The recorded time becomes part of your history, which is what makes a timer useful beyond a phone stopwatch — you can look back at whether you are actually improving or just having a good day.

Because it is a web app, the practical trade-offs are:

• Convenience: nothing to install, and it works on whatever device has a browser.
• Dependence on the browser: the page needs JavaScript enabled to run at all, so a locked-down machine or a blocked script will leave you with a blank page.
• Input method: keyboard or on-screen controls are the norm for browser timers, which is fine for casual practice but feels different from the physical stackmat pads used in official competition.

Who it suits

The main audience is casual and improving solvers — people drilling algorithms, chasing a personal best, or tracking an average of five or twelve solves. If your goal is competition simulation with a stackmat and a display, a dedicated timer setup will serve you better. If your goal is simply to know how fast you are and whether you are getting faster, a browser timer removes almost all friction.

A useful next step

Open it in a browser where JavaScript is enabled, do a few untimed solves to get comfortable with the controls, then run a session of twelve solves and look at your average. The average matters more than any single time, because one lucky solve can flatter your progress while a consistent average shows real improvement.

If you later want a broader set of training tools, compare it with other cubing resources such as J Perm for algorithms and CubeSkills for structured lessons.

How does Speedcube time my Rubik's Cube solves?

Speedcube is a browser-based timer for Rubik's Cube solves: you start the clock, solve the cube, then stop the clock, and the app records the elapsed time for that attempt. It is a straightforward, single-purpose web tool rather than a training program or coaching service.

Because it runs in the browser, the practical flow is usually: open the page, wait for it to load, then use the timer controls or keyboard to begin and end each solve. The page evidence indicates the app requires JavaScript to run, so the timer itself is generated client-side in your browser rather than by a server sending you a stopwatch reading. That means the accuracy you experience depends mostly on your device and browser responsiveness, not on network latency after the page has loaded.

What this means in practice

For a typical user, the value is in repeated, low-friction timing. A cuber doing a session of 12 or 50 solves wants to start the next attempt immediately, see the time, and move on. A browser timer like Speedcube fits that loop well: no install, works across desktop operating systems, and keeps the interaction simple.

Trade-offs to expect from a web-based solve timer:

• Convenience: You can use it on a shared or borrowed computer without installing anything.
• Dependence on the browser: A heavy tab load, background processes, or a slow device can affect the feel of the timer.
• Limited context: A basic timer records times; it does not, by itself, teach you algorithms or diagnose why a solve was slow.

A useful next step is to test the timer in the conditions you actually solve in: on your normal device, with your usual keyboard setup, and for a full session rather than one solve. If you are comparing options, look for whether a timer supports keyboard start/stop, session history, and inspection countdown, since those features matter more to regular practice than visual polish.

Can I use Speedcube to practice for a competition?

Yes. Speedcube is a web app for timing Rubik's Cube solves, which is exactly the kind of tool competitors use for daily practice. The main caveat is that it runs in a browser, so you need JavaScript enabled and a reliable connection to load it.

What it can and can't do for competition prep

A timer helps you build the habits that matter on competition day: consistent inspection, fast starts and stops, and tracking your averages over many solves. What a browser timer typically can't replicate is the full competition environment, so treat it as a training tool rather than a simulation.

A practical routine

If you're preparing for a specific event, decide which event you're training (3x3, 2x2, one-handed, and so on) and set a session goal, such as 50 solves with a focus on lookahead rather than raw speed. Record your best and worst solves as well as your average, because competition results depend on consistency across five solves, not one lucky fast time. If you want a second timing option, CS Timer is a widely used browser timer with detailed statistics.

Before you register

Learn the WCA regulations for your event, especially inspection limits, puzzle defects and solving procedure, and practise with a physical timer if one will be used at your competition. Use Speedcube for volume and data, and simulate competition conditions separately: five solves in a row, no restarts, with someone watching if possible.

Does Speedcube work on a phone or tablet?

Yes. Speedcube is a web application for timing Rubik's Cube solves, so it runs in a mobile browser rather than as a native app. On a phone or tablet, that generally means you can open it, start a timer and log solves without installing anything.

The practical trade-offs matter more than the yes/no answer:

• Touch timing: A browser timer responds to taps, so you can start and stop a solve with a finger. Whether that feels precise depends on the screen and your tapping style; a physical timer or keyboard is usually more consistent for serious speedcubing.
• Screen size: On a tablet, the timer is easier to read at arm's length and the scramble text is more comfortable. On a phone, large digits still work but you may want landscape orientation.
• Browser behaviour: Because it is a web app, features depend on the browser. Keep the tab active, avoid aggressive battery-saving modes, and check that JavaScript is enabled — the page itself notes that JavaScript is required to continue.
• Session continuity: If you solve on a phone and later on a laptop, you may need to check whether your times sync between devices, since that is not guaranteed by a browser-based tool.

For a concrete scenario: a casual solver practising on the sofa can use a phone or tablet without setup, while someone chasing personal bests might prefer a tablet with a stand or a keyboard-equipped device for cleaner start/stop input.

A useful next step is to open the app on your own device and run a few test solves, trying both portrait and landscape and comparing a tap with a keyboard press if one is available. If consistency matters to you, that quick test will tell you more than any general claim about mobile support.

How do I track my solving progress over time?

The honest answer for Speedcube is that its public page doesn't describe any progress-tracking features — the only content visible is a note asking you to enable JavaScript, which suggests the timer runs entirely in the browser. So the reliable way to track progress over time is to build the record yourself: after each session, note the date, session type (solo, timed, or average-of-five), and your times, then review the trend weekly rather than solve-by-solve.

A simple tracking routine

• Log the raw data. Record every individual solve time plus the session's best and average. Averages smooth out lucky scrambles; single bests show your ceiling.
• Separate practice modes. Times from casual solving, deliberate slow practice, and timed attempts aren't comparable, so keep them in different columns or tabs.
• Review on a schedule. Once a week, compare this week's average against last week's. Daily comparison mostly shows noise.
• Note what changed. If you switched method, learned new algorithms, or changed cube, write it down — otherwise a sudden jump looks mysterious later.

Choosing where to keep it

If automatic history matters more to you than using this particular timer, compare a few established options before committing, for example CS Timer or CubingTime, both of which are built around stored solve history. Speedcube may still be perfectly usable as a straightforward timer — just plan on exporting or copying your times out if you want a long-term record.

Next step

Do one timed session today and immediately write the results into a spreadsheet with columns for date, time, and notes. After two weeks you'll have enough data to see whether your average is actually falling, which is the only progress signal worth acting on.

Is Speedcube free to use?

Speedcube is described as a web application for timing Rubik's Cube solves, and there is no indication on its site that it charges for access. Nothing in the available page evidence shows subscription tiers, paywalls, or payment options, so the reasonable expectation is that you can use it at no cost.

What to check before relying on it

• Whether an account is required. A free timer may still ask you to sign in to save solve history across devices.
• What "free" covers. Some timing apps keep the basic timer free but charge for extras such as detailed statistics, cloud sync, or scramble generation.
• Whether ads appear. Free web tools often offset costs with advertising, which can affect how the interface feels during fast solves.

A practical way to decide

If you just want a stopwatch for casual solves, open Speedcube in a browser and try it directly — that costs nothing and takes seconds. If you need persistent solve history, cross-device syncing, or advanced breakdowns like inspection timing and averages of 5/12, test those specific features before committing to it as your main timer.

One caveat: the page content available for Speedcube is minimal, so treat the free-to-use conclusion as the default assumption rather than a confirmed pricing policy. Confirm on the site itself if cost is a deciding factor for you.
