About Exactish — Daily Senses Test
How exact are your senses? Exactish gives you six short tests every day, and everyone in the world gets the same six.
THE SIX TESTS
• Hidden clock: stop at the given second. The clock vanishes after the first second, so you count in your head.
• Angle: open an angle of the given number of degrees.
• Colour from memory: a colour shows for three seconds, then you rebuild it from lightness, chroma and hue.
• Dots: dots flash for 1.2 seconds. How many were there?
• Split: mark a given percentage of a line.
• Fill: hold the button and the tank fills at a speed that changes every day; let go at the given percent.
HOW IT IS SCORED
Every answer is measured in its own natural unit: relative timing error, degrees, the CIEDE2000 colour difference, the log-ratio of the count, and percentage points along the line and up the tank. Each test turns that error into an exactness score from 0 to 100, and the day's card shows the six as coloured squares you can copy and share.
WHAT ELSE
• Unlimited practice rounds, separate from the daily game.
• A day streak.
• Retry your weakest test.
• Albanian and English.
• No account. Your results stay on your phone.
The six tests change every day at midnight UTC.
