Land on the target time.

How Hit works

You're given a target time. Tap to start the clock, then tap again when you believe the target has arrived. The clock is never visible while it runs, so there is nothing to read and nothing to react to. Five rounds make a run.

Note what changes from Guess: you aren't judging a duration someone else chose, you're producing one to order. Psychologists treat estimation and production as separate abilities, and plenty of people are visibly better at one than the other. If your Hit scores and your Guess scores don't match, that's the reason.

What a good score looks like

Because the target changes every round, judge yourself on percentages rather than on seconds. Within 10 per cent is a respectable round, within 5 per cent is good, and a run averaging above 90 means your internal clock is calibrated to a degree most people never test.

Three ways to get better

• Launch the second tap early. Your finger takes time to arrive. If you wait until the target feels reached and then start moving, you land late every round, a consistent bias that looks like bad timing but is really a motor delay.
• Give yourself a rhythm. Producing an interval is far more accurate when it rides on a pulse than when you sit still and wait for a feeling. Establish the beat before you tap to start.
• Tap the same way twice.Same finger, same distance, same force. Change the movement and you change the lead time you need, which adds variance you can't see.

The common mistake

Second-guessing near the end. The last stretch before the target is where doubt arrives, and a hesitation of a quarter of a second wipes out an otherwise perfect round. Commit to the moment you picked. Reaction time vs anticipation is the guide for this mode: the gap between responding to a moment and arriving at one is where the whole score lives.

The other four modes

Temvo is five disciplines, and “a sense of time” turns out not to be one skill. Most people are markedly better at some of these than others.

• GuessWatch a hidden timer, then say how long it ran.
• EchoHear an interval, then reproduce it.
• TempoLock onto a beat, then hold it after it goes silent.
• 9.99Stop the timer on 9.99, with the last seconds blurred out.

Or play all five in one run as today's daily challenge, where everyone gets the same rounds and you get a single shot at them.
