Why Another Cube Timer?

Speed Cube Timer

There are already some fantastic cube timers out there — csTimer, Twisty Timer, and others have served the community well for years. But I wanted something that felt a bit different:

• Instant to use — no login, no install, just open and start
• Competition-ready — with proper WCA inspection time
• Clean and modern — a minimal UI I’d actually enjoy using every day

So I built one as a personal project, and now I’m sharing it with you.

Features That Matter

WCA-Style 15-Second Inspection

Just like official competitions, you get a 15-second inspection countdown before solving. Audio alerts at 8 seconds and 12 seconds help you stay on track. Go over 15 seconds? The timer automatically applies the correct penalty (+2 or DNF).

You can also turn inspection off if you prefer to start immediately.

Real-Time Statistics

See your best time, Ao5 (Average of 5), and Ao12 update live as you solve. Tracking your progress has never been easier — no spreadsheets required.

Works Offline (PWA)

Add Speed Cube Timer to your phone’s home screen and use it like a native app. Once loaded, it works completely offline — perfect for practicing anywhere, even without internet.

Dark Mode & Light Mode

Long practice sessions? Switch to dark mode to reduce eye strain. Practicing outdoors? Light mode keeps things visible. Toggle anytime in settings.

Your Data, Your Control

No account required. Your solve history is stored locally in your browser. Need to transfer data to a new device? Just export to JSON and import it anywhere.

How to Use

1. Open sct.yo4e.com on any device
2. Tap the button or press Spacebar to start
3. Stop the timer when you finish solving
4. Mark penalties (OK / +2 / DNF) if needed
5. Track your progress with built-in statistics

That’s it. No sign-up. No downloads. Just cube.

Who Is This For?

• Beginners who want a simple, no-fuss timer
• Intermediate cubers tracking Ao5 and Ao12 improvements
• Competitors who need WCA-compliant inspection practice
• Anyone who wants a beautiful, fast timer that just works

Try It Free

Speed Cube Timer is free to use. The main timer screen is completely ad-free so nothing interrupts your solves. (You’ll only see minimal ads on secondary pages like History or Settings.)

Give it a try and see if it fits your practice routine.
