Online timer for 169 seconds

You have started the countdown again because the first pass missed a shoulder, the backs of your legs or another patch before you head outside. Two minutes and forty-nine seconds gives you a brief, defined window to spread the remaining sunscreen, check the areas exposed by your clothes and put the cap back on without turning the morning into a long delay.

While you finish this second application, keep the countdown page open and the screen awake. Closing its tab or browser may stop the countdown or clear its progress, leaving you unsure how much of the interval remains. If you need to check the UV forecast or message someone, use another tab or app while leaving the countdown running, particularly when you are preparing near the door, at the beach or beside the local pool.

With sunscreen on your hands, a phone is usually easier to keep nearby and glance at while moving between the bathroom, bedroom and front door. Place it on a dry bench where the display stays visible and taps are unlikely. A laptop can suit a fixed setup, such as applying sunscreen beside a desk before a lunchtime walk, but it is less convenient when you need to turn around, reach your back or move through the house.
