• The stopwatch no longer punishes you for tapping it late. You start at a door, the phone is still in your pocket, and the ten minutes before you remembered were served all the same. While a run is going, Today now shows the hour it began — tap it and move the start back, five minutes at a time, by how late you were, or straight to the hour you know. The run keeps counting the whole time and nothing is written down until you stop it. • The lock screen and the Home Screen widget follow the correction in place, so the same run is the same run wherever you look at it.
