Set the timer to 87 minutes

Online timer for 87 minutes

You have settled beside the pool for your child’s second swimming session in a row, with another eighty-seven minutes covering the lesson, changing time and the slow shuffle back through the showers. The countdown keeps the whole stretch together while you watch from the stands, answer a few messages or sort out the afternoon without repeatedly checking the pool clock.

While the lesson moves from warm-up laps to drills, your phone may dim or lock well before the swimmers finish. The countdown should continue behind the dark screen, so there is no need to keep waking the display and losing track of what is happening in the lane. Near the expected finish, checking the remaining time gives you enough context to pack up and be ready by the change rooms.

For two consecutive sessions, a mechanical ring timer can become awkward because its markings are coarse and the second turn may begin from a slightly different point. A precise countdown keeps the planned pool time intact across both blocks. If the instructor runs a little late, let the alarm mark the scheduled finish, then use the pool clock for the extra minutes rather than restarting and confusing the original plan.
