NO Advertising, Math Simply is an easy-to-use calculator with a minimalist design that allows users to place the calculator on the Home Screen of their iOS or macOS device to perform calculations directly without opening the app itself. The widget calculator has an almost identical calculation experience to the main APP. Version 2.0.0 introduces a brand-new unit converter feature, offering conversions for over 100 units across 10 categories, with more content to be added in future updates. It has the following features: 1. Easy-to-use interface – has the same design interface as the traditional calculator, simple and clear. 2. Has almost the same widget calculation experience as the main program (the widget calculator only lacks the cache memory function). 3. Adopts the cache memory function and provides four cache operation buttons, which is convenient for diversified calculations. 4. User-friendly hints – hints for β€œPrevious Result”, β€œcurrent operator” and operation status during calculations. 5. Global Localization – Math Simply not only supports 12 languages, but also provides globalization support, whether you are used to using β€œ.” or β€œ,” as a decimal point, or β€œ,” or β€œβ€˜β€ as a thousands separator, Math Simply adapts to your needs in real time. 6. Personalization – For display modes, button vibration, button shapes and colors, and even display fonts, Math Simply offers adjustments to provide a variety of personalized settings. 7. Unit Converter - Quick and intuitive unit conversions, with customizable precision control. 8. Future Upgrades – Math Simply is a one-time purchase and download for life, with access to all future upgrades (including more convenient calculation features). Math Simply currently supports all iPhone and iPad devices with iOS 17 installed. In addition, thanks to the characteristics of the M series chips, Mac with Apple Silicon chips can also install this app and use the Widget Calculator function. In the near future, Math Simply will also add more convenient features, aiming to help users calculate more conveniently. Thank you for your support!

About

Dozen Clock

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
