155 Second Timer

Need just the right amount of time to get something done without it dragging on? A 155 second timer—2 minutes and 35 seconds—strikes that perfect balance. It’s long enough to knock out a quick task but short enough to keep your focus sharp. This countdown timer fits neatly into those awkward in-between moments in your day that often go to waste.

Why Use a 155 Second Timer?

Sometimes, all you need is a little structure to push through hesitation or procrastination. A one 155 second timer can help you:

Do a fast desk clean-up using the speed cleaning timer
Stretch or move between meetings with the stretching routine timer
Warm up before your workout or HIIT session using the HIIT workout timer
Take a breathing break using a focused meditation timer

It’s the kind of timer that helps you shift gears, focus up, or finish what you started—fast.

Run It Anywhere with an Online Timer

You don’t need a stopwatch—just an online timer. Setting a timer for 155 seconds is easy, fast, and totally flexible whether you’re on a desktop, tablet, or phone. Use it during a content sprint with the content creation timer or while prepping ingredients with the meal prep timer.

What Can You Get Done in 2 Minutes and 35 Seconds?

Write out your top three priorities for the day
Rehearse a presentation intro using the speech rehearsal timer
Make a cup of coffee and use the coffee brewing timer
