A clip on lap counter is a small, easy-to-use device that helps you keep track of laps while swimming, running, or doing any repetitive activity. Whether you are a swimmer in a pool or a runner on a track, it’s easy to forget how many laps you’ve completed. This is where a clip on lap counter becomes your best friend. You simply clip it on your finger or clothing, press a button after every lap, and it counts for you. No need to remember in your head anymore.
