What a 2 minute 30 second timer is good for

Two and a half minutes is the brewing time printed on many tea boxes for a lighter cup, and a practical rest interval between heavier sets.

Steeping tea

Oolong and lighter black teas often brew best at about two and a half minutes.

Rest intervals

Rest for two and a half minutes between heavy compound lifts.

A timed drill

Two and a half minute rounds are used in some sparring and fitness drills.

Microwave meals

Many ready meals need about two and a half minutes before a stir.

To pace yourself, glance at the disc rather than the numbers. With the 2 minute 30 second timer running, half the colour has gone after 1 minute 15 seconds, and when only a quarter is left you have 37 seconds to wrap up. Open fullscreen if the timer needs to be read across a room, and add a label so everyone knows what the 2 minutes 30 seconds are for.

Why use this timer

Why a visual timer helps

A shrinking disc turns time into something you can see. You read how much is left at a glance, without doing sums on a clock, and an invisible deadline feels less stressful when you can watch it approach. That is why visual timers are a staple in classrooms and are widely used by people with ADHD and autistic children and adults. Read our guide to using a visual timer, how it helps with ADHD time blindness, classroom transitions and autism.

Why this timer is accurate

The countdown is anchored to your device clock rather than counted in animation frames. It does not drift if you switch tabs or your screen sleeps: it keeps running in the background and still sounds the alarm on time. When you come back, the disc jumps straight to the correct position.
