Please note: This app is currently available in Japanese only. Wadokei is an app for reading the “koku” of Japan’s Edo-period temporal hour system, adjusted to your current location and the season. Because day and night are each divided into six parts, a daytime koku is longer in summer, while a nighttime koku is longer in winter. Enjoy a sense of time shaped by the sun and daily life, unlike the modern 24-hour clock, through a dial inspired by traditional Japanese perpetual clocks. Main Features: - Shows the current koku using the zodiac sign and traditional bell name - Calculates the length of day and night based on Akemutsu and Kuremutsu - Supports location presets in Japan and around the world - Calculates koku using your current location - Shows moon age, the 24 solar terms, and the sexagenary cycle - Supports Apple Watch, complications, and Smart Stack - Lets you schedule notifications for twilight times Location information is used only when you select your current location, and only to calculate koku on your device. Precise latitude and longitude are not shown in settings or screenshots, and are never sent externally. Time that stretches and contracts with the seasons is something a modern clock alone cannot reveal. Look up at today’s sky, and let it overlap with the hours of Edo.

Put time where it belongs: on your Home Screen, Lock Screen, Apple Watch, Apple TV, Mac, or the biggest display in the room. Ambient Time is a native collection of clocks and useful glances. Explore 47 ways to read the moment on iPhone and iPad—from precise word grids and binary displays to astronomy, weather, mathematics, and generative art. ONE HOME FOR EVERY SCREEN The destination-first control center organizes Widgets, Apple Watch, TV & Displays, Clocks, and Instruments. Browse what fits each surface, preview it live, and choose starting defaults without pretending to control system-owned placement. CLOCKS WITH A POINT OF VIEW • Word Clock spells out time in nine languages plus IPA. • Cosmic brings the sun, moon, horizon, and zodiac into one quiet astrolabe. • Tide follows local predictions and highlights the next high or low. • ASCII World Clock wraps global hours around a text-art globe. • Moon Track follows the live lunar phase. • About Time turns optimistic phrases into the hands of a clock. • Inkwell Ledger lets the day unfold as a handwritten journal. • Mandaza draws a generative clock that never repeats exactly. WIDGETS MADE FOR THEIR SPACE Ambient Time groups Home Screen clocks and information widgets by size, so every layout stays clear and useful. Because the Lock Screen already shows Apple's clock, Ambient Time adds context instead: moon phase, golden hour, rain, tides, and poetry in Inline, Circular, and Rectangular forms. A CALMER GLANCE ON APPLE WATCH Choose from six legible clocks in the Watch app. Add nine Smart Stack widgets and complications for tides, rain, forecasts, golden hour, moon phase, world moments, words, compliments, and poetry. MADE FOR THE ROOM—AND THE MAC Apple TV offers a remote-first gallery of Ambient clocks and fixed dashboards. Mac brings the same destination control center to the desktop, including fullscreen Ambient Mode, dashboards, and Desktop or Notification Center widgets. Five global color themes are available where a clock supports them. Weather, sun, moon, and tide features use coarse location only with permission. There are no accounts, ads, subscriptions, or purchases, and location is never used for tracking. Built natively in SwiftUI with Reduce Motion support. Made by Luke Steuber.
