A treadmill timer you won’t want to cover with a towel.

Introducing RunKWC, a super lightweight treadmill timer for your phone. No ads. No paywalls. Absolutely free. Just enter your time, place your phone on your treadmill ledge, then run.

Cycle through six timers with the tap of a finger. You’ll get you through your runs far better than with that energy-sapping timer you cover with your gym towel anyways. Log your time after your run right in the app too.

RunKWC helps you get through the mental struggle of running. Here's my post explaining how.

Note: RunKWC is made for mobile devices. Read all about in on your laptop, then go back to this link on your phone or tablet to install it!

Six wonderful timers out of the box.

Grinding through your run is easier when you see progress in different ways. When you cross micro-milestones. When you get that hit of dopamine over and over again. Just tap the screen to change the way your time is visualized.

**Decaseconds**: Declutter your mind with a pulsating number that ticks down 0.1 every second.

**10x30**: Break down your run into micro-milestones. In 10 and 30 groups and groups of :10 and :30 seconds.

**Up-and-down**: See your run progress from red to bright yellow. Your remaining time grows in size as it descends.

**Half-life**: Seven intervals that are half the duration of the previous one. Progress faster as your energy winds down.

**Runner's dozen**: No numbers to distract your mind. Just ten donuts being eaten away until the satisfying end.

**Over-the-hill**: Hill intervals based on time. Feel the early climb, speed of the middle, and late descent.

*- RE-ZERO: Re-start progress by tapping the left-half of the screen. Your timer length stays the same but the animations start over (and go faster with less time remaining). It's a huge motivation boost—especially during the latter stages of your run!

Tap around and find out.

Here’s a quick 1:00 run. Tap to move to the next timer. On Rezero-able timers, tap the left-side to “zero-out” and reset your progress. Stay 1 minute, get your medal! (You’ll see.)

We want you to love RunKWC.

And when I say we, I mean me—Ka Wai Cheung, the creator of this app. Yes those are my initials right there in the name. Pronounce it “run-k-w-c” or “run-quick”, whatever you fancy.
