About

Dozen Clock

Features
Read full description

Dozen Clock shows the time in a different way than other clocks and watches. In digital and analog format, too. It enables the user to have a tricky but still precise display of time enabling perhaps new ideas to root and grow. Released currently exclusively for Apple products, the application is able to display the date also in the format according to the Japanese calendar. INSTRUCTIONS: The biggest rectangle in the middle shows the minutes ( numbers outside the circle ). The small rectangle in the middle shows the hour ( darker numbers inside the circle ). The small red rectangle in the middle shows the seconds ( no numbers since it functions like in normal clocks ). "Think different." - Steve Jobs

Zulu Time brings Zulu (UTC), local time, world-clock planning, UTC alarms, and original instrument-inspired displays together in one focused app. AT A GLANCE • View live Zulu and selected local time side by side. • Configure Zulu and local time independently: 24-hour, 12-hour, or military format, optional seconds, and separate date styles. • Detect your current time zone automatically and refresh it as needed, or manually choose from 111 countries/regions and 126 cities and aviation hubs. PLAN THE SAME MOMENT WORLDWIDE • Select an exact UTC date and time up to seven days ahead or behind. • Move by 15 minutes, one hour, or one day. • Compare the same moment across saved world clocks with UTC offsets, DST status, and day-boundary indicators. • Read ISO 8601, aviation DDHHMMZ, and YYDDD ordinal codes. ZULU ALARMS • Schedule alerts directly in UTC and review the local-time conversion before saving. • Create one-time, daily, or weekly alarms. • Choose sound on or off and snooze for 10 minutes. ORIGINAL THEMES • Choose from 17 brand-neutral designs: six modern aviation displays, seven premium analog dials, and four minimal themes. • Supported aviation themes can use the on-device compass for live heading; heading scales in other themes are decorative. • Premium dials display both Zulu and local time without covering the dial. IPHONE, IPAD & APPLE WATCH • Configurable Home Screen, Lock Screen, and StandBy widgets. • A full Apple Watch app with all 17 themes. • Zulu/local and Zulu/date complications. • Sync the selected place, time zone, theme family, and verified subscription status from iPhone. PRIVATE BY DESIGN • No ads. • No Zulu Time account. • No cross-app tracking. Zulu Time requires an auto-renewing monthly subscription. Eligible new subscribers can receive a 7-day free trial. The localized price and renewal terms are shown before confirmation, and the subscription can be managed or canceled in Apple Account settings. The aviation displays are visual clock themes only. They are not calibrated or certified flight instruments and must not be used for navigation. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
