Swimming revolves around time.

The pace clock is the focal point of swim practice.

And swim practice is at the heart of our sport.

 We’ve made pace clocks great again.

And transformed your phone into your very own personal pace clock.


pace clocks for swimming pools

We’ve re-invented the pace clock by listening to dozens of coaches, swimmers, and triathletes just like you.


Pace Clock Features:

  • It can count up
  • It can count down
  • Bluetooth enabled, it connects to our Swim Practice mobile app which allows you to program any set your heart desires
  • LED’s made specifically for outdoor viewing are visible from 100 meters away
  • 8 hour battery life when not plugged in (AC 110~240V)
  • Easily mountable or self-standing
  • USB port to update clock software
  • Ruggedly built to withstand outdoor conditions; splashy kids; slips, trips, and falls
  • Two year warranty
  • 30″ x 2.5″ x 12″ (L x W x H)

We wanted to create something for everyone so we’ve made the mobile app to do just that.


Swim Practice App Features:

  • Swim Practice can be used without the swimnerd pace clock as your personal pace clock which is especially awesome for Master swimmers, triathletes, and fitness focused folks
  • Share your swim practices with your team, teammates, or with the global network of swimnerds
  • Set goals for all events over all courses (SCY, SCM, LCM)
  • Keep track of your yardage, calorie burn, best times, and practice records
  • It’s free

We hear you loud and clear, fellow swimnerds.
