Do I need an account?

No. Stats are saved on your device by default, but you can sign in with a passwordless email link or Google to keep your streak on every device.

How do I stop the clock?

Click the Stop button or press the Space key. On iPhone and iPad the clock stops automatically when the music fades out instead of continuing to run.

What if videos won't load or my timing feels off?

The site suggests switching off your VPN if videos aren't loading, and notes that Bluetooth headphone delay can cause timing to seem off.

Can I share my results?

Yes — you can copy your results to paste into a group chat or Discord, and share a results image.

vocalstim — Cue the vocals: stop the clock when singing starts

vocalstim is a daily music-timing game: you hear the intro to three songs, the music fades out before the vocals, and you have to stop the clock at the exact moment the singing would kick in. New songs drop every midnight, scores are out of up to 1,250 points per song (1,000 plus a 250-point bullseye bonus), and longer silences give you extra leeway. It's free to play in the browser, works with a keyboard shortcut (Space to stop), tracks streaks and stats, and offers optional sign-in to sync your streak across devices.

Key Features

Daily three-song challenge

Every day at midnight you get three new song intros to play; past stims can be replayed any time if you missed one.

Fade-out timing mechanic

The intro plays with a running clock, then the music fades out before the singing begins — you must keep the song going in your head and hit Stop at the exact moment the vocals would come in. On iPhone and iPad the clock stops instead of continuing.

Scoring with bullseye bonus

Up to 1,000 points per song based on how close your stop was, plus 250 bonus points for a bullseye; longer vocal gaps get more leeway.

Streaks and stats

Track a daily streak and personal stats locally on your device, or sign in (passwordless email link or Google) to keep your streak synced across devices.

Guided practice song

A practice mode lets newcomers learn the mechanic before jumping into the daily songs.

Sharing and community

Copy your results to paste into group chats or Discord, share a results image, and send feedback directly to the developer via a built-in form.

How It Works

Hear the intro

The song intro plays and a clock starts running with the music.

The music fades out

The audio fades before the singing starts, but the clock keeps running (on iPhone/iPad it just stops).

Stop the clock

Keep the song going in your head and hit Stop (or press Space) the moment the vocals would come in.

Hear the real thing

You then hear the actual vocal drop and see how close you got, earning up to 1,000 points plus 250 for a bullseye.
