Two cities. 24 hours. Green means both of you are awake and working. Tap the row. Copy the message. Done in under a minute. Clock Zone Timing is a scheduling tool for people who regularly need to find a time that works across two different timezones, without doing mental arithmetic. Open the app and you see a strip of twenty-four rows — one for each hour of the day. The left column shows the hours in your city. The right column shows the corresponding time in the other person's city. Every row is the same moment in time, expressed in two different timezone labels. The rows are color-coded: green for the hours when both of you are in working hours, dark for the hours when one of you is asleep, amber for early morning and evening. The overlap is visible in one glance. You do not calculate anything. Tap a green row and a formatted message fills the field below: "Does Thursday 9am London / 5pm Tokyo work for you?" One tap copies it. You paste it into the message thread. The whole process takes under a minute. A day selector lets you check tomorrow or any day in the coming week — useful because daylight saving transitions and day-boundary crossings change the overlap on specific dates. A swap button flips the two cities. City pairs you use regularly can be saved as one-tap chips. The search covers a hundred and fifty cities worldwide. A home screen widget shows the current overlap status for your most-used pair — how many hours of overlap remain today, or how long until the next window opens. An optional notification fires fifteen minutes before the overlap window opens for any saved pair. No account. No calendar access unless you choose to create an event. No data leaves the device.
