Hi everyone!

I’m the developer of myumyuTimer, a speedcubing timer that runs in your browser.

It brings everyday practice, smart cube features, and online battles together in one place.
Time your solves and organize your results by event and session.
Review your practice with solve history and statistics.
Connect a smart cube for automatic timing, solve analysis, and 3D replay.
Practice with friends online, using the same scramble. You can create rooms for up to 5 players for free.
Share a solve and let others try the same scramble.
Sync your records across devices, back up your data, and import or export csTimer data.
Practice offline after the first online setup.

Try it here:

I’d love to hear what you think! Is it easy to use? What works well, and what could be better? Bug reports and feature ideas are also welcome.

Thanks for trying myumyuTimer!
 
Thank you for your reply!

To delete an older solve, press and hold its time if it is visible on the screen.

Only a few recent solves are shown there. For earlier solves, go to HIS → LIST to see the full list, then press and hold the solve you want to delete.

If you have any other questions, please feel free to ask!

Hi again! If you’ve tried myumyuTimer, I’d love to hear your feedback.

Was anything confusing or difficult to use? Is there anything you liked, or something you felt was missing?

Even a short comment would help me improve the app. You can reply here or contact me on X: @myumyuFactoryJP.

Thanks for giving it a try! 🧩
