Clock-Out Timer keeps one number in front of you: how much of today is left. Working late usually isn't a willpower problem. It's a time-awareness problem. When the time remaining is simply there, in view, deciding to stop gets a lot easier. ■ Visible without opening it At your start time, the time left and a progress bar appear on the Lock Screen and in the Dynamic Island. There are widgets, Lock Screen widgets, Apple Watch complications and a StandBy desk clock too. You never have to open the app. ■ It changes colour as you get close Under an hour to go, it turns orange. At your end time, it says so. Past it, it turns red and counts your overtime, so you always know how far over you are. ■ End your day with one tap "Done for Today" stops today's notifications and the countdown. Marking the end is often what makes the end happen. Staying a bit longer? Extend by 15, 30 or 60 minutes. Stepping away? Start a break. All of it works from the Lock Screen. ■ Build a streak of finishing on time Days you leave on time are recorded automatically and counted as a streak, with days off skipped. It's one more reason to call it a day. ■ Notifications, at your volume Choose Off, Minimal, Standard or Custom. Beyond start and end reminders, you can set your own checkpoints through the day and a countdown before you finish. ■ Quiet on your days off Pick which weekdays you're off and the app stays silent — no notifications, no Live Activity. Finish on time a little more often.
