This app allows you change the size of the clock, to have both a digital and analog clock displayed at the same time, a second time zone, to add colors inside the clock digits, and more. There is an emoji that you can change it's size on the screen. It has a battery indicator ring that changes color depending on the battery level and you can also change it's size. You can also make the screen really dim so that you can have it displayed by your bedside. Choosing dark colors and images ensures that the battery will not be greatly affected utilising OLED technology device panels found in later model iPhones. For changes or requests you can always contact us and we will try our best to implement it for you in the next update! *Disclaimer - This version of the will not display icons related to calls or messages within its screen. a href="https://www.freepik.com/vectors/background" Background vector created by starline - www.freepik.com a href="https://www.freepik.com/vectors/star" Star vector created by macrovector - www.freepik.com

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
