Hourline: World Clock
Time zones, weather & widgets
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Hourline is a world clock and time zone app for iPhone, iPad, and Apple Watch, designed like a
living poster.
The city you care about fills the screen: its time in large numerals beside the red hour
line, the date, a rolling seconds drum, its day length, sunrise and sunset, and the weather.
The whole page is that city's scene, its sky right now and its landmark, with the sun where
it stands or the moon and stars at night, and the city's rain, snow, cloud, or fog over it.
Drag across the page to turn the city's day to another hour, tap the weather for its forecast,
and share the page as a postcard or a story. Switch between 12- and 24-hour time, and between a
light and a night look, with a tap.
World Time lists your cities as cards, each with its landmark under its own sky, its offset,
local time, and weather. Choose one and a follow spot swings over to it. Hold a card to move
it, and swipe it left to remove it. Drag the ruler of your own day to see every city at another
moment, with your calendar's events on it if you like, and plan an event on any city's clock
to add to your calendar or send to the others. Turn to the map to see day and night across the
world, with your cities on the red hour line, and drag the map or the UTC ruler from one city
to the next.
Widgets bring it to your Home Screen and Lock Screen:
• Clock: one city's time, set like the app.
• World Time: your cities as cards.
• Hour Line: the map around a city, its country filled in, night shaded.
• City Time for the Lock Screen.
• Landmark, with Hourline Pro: the city's landmark under its sky right now, in three sizes.
A Live Activity keeps up to three cities on the Lock Screen and in the Dynamic Island.
Apple Watch shows each saved city under its own sky and landmark, led by its weather. Keep city clocks, weather and landmarks on your watch face with complications and in the Smart Stack.
Details that matter:
• Real time zones and daylight saving time from the system.
• Sunrise, sunset, and day length calculated for each city.
• Weather from Apple Weather.
• 199 cities, each with its own landmark illustration.
• Quiet sounds of wood, paper, and brass, which you can turn off.
• No ads and no tracking. Your cities stay on your device.
CITY STROLL (iOS 27)
On an iPhone or iPad that supports Apple Intelligence, open City Stroll from a city's clock.
Leo, Jack, and Mia share a fictional conversation as they explore real places in the city.
Discovered stops appear on a map, while local time and available weather give the conversation
context. The first three lines are free; Hourline Pro lets the stroll continue. Availability
varies by device, language, and region.
HOURLINE PRO
Hourline is free with up to six cities and the weather of the city on your clock. Hourline Pro
keeps as many cities as you like and brings every city's weather, with its forecast hour by
hour and for ten days. It lets City Stroll go on for as long as you like, adds the Landmark and
City Stroll widgets, and adds the events you plan across your cities to your calendar. Choose
Yearly, an auto-renewing subscription, or Lifetime, a single purchase.
Payment is charged to your Apple Account when you confirm the purchase. A subscription
renews automatically unless it is canceled at least 24 hours before the end of the current
