How it works
This lap counter clicker adds one lap each time you tap the button or press Space. Load a distance and it beeps on the last one, such as length 16 of a 400 m swim in a 25 m pool.

Count to a distance
Open More options and pick a preset, or press its name in the list under the tool. The line under the button says how many are left, and one beep sounds on the last.
Pool lengths and track laps
A pool preset counts lengths: 400 m, 800 m and 1,500 m in a 25 m pool are 16, 32 and 60. On a 400 m track, 1,600 m is 4 laps, 3,200 m is 8 and 10,000 m is 25.
Several lanes at once
Six lanes, a key each gives each lane its own counter on keys 1 to 6. Four walkers or runners with a total adds up the laps of a group.
Questions and answers
How many laps is 1,500 m in a 25 m pool?
60 lengths, because 1,500 ÷ 25 = 60. In a 50 m pool the same swim is 30 lengths. Each pool preset on this page counts one length of the pool with each tap.
Is a lap one length of the pool or two?
Usage differs. In swimming a lap most often means one length of the pool and, less commonly, one length and back. The pool presets count single lengths, and Lengths into laps, two lengths a lap keeps both numbers.
How many laps of a track is a mile?
Just over 4. A mile is 1,609.344 m and lane 1 of a competition track is 400 m, so a mile is 4.02 laps. Four laps are 1,600 m, which is 9.344 m short of a mile.
Can it count laps by itself while I swim or run?
No. The count goes up only when the button is tapped or Space is pressed; the page reads no motion and no location. A walker can tap a phone each lap, and for a swimmer someone on the pool deck taps.
