iOS 17 has brought us interactive widgets, and we immediately thought about how to provide a better experience for our users. Just a few days later, the inspiration for a calculator struck! The interactive widget feels like a dedicated addition to the calculator, allowing users to perform daily calculations right on their home screen without having to open the app. Unlike most calculators, we display both the calculation process and the result simultaneously on the interface, making it easier for users to follow the entire calculation process. Additionally, we save all calculation results locally, enabling you to review past calculations whenever you need. If you wish, you can even synchronize these results across your devices using iCloud. There is one known issue: Rapidly tapping the interactive widget may cause the app to open, so a few of our fast users may need to slow down a bit for now. We are committed to perfecting this feature, so if you have any suggestions or feedback, please don't hesitate to contact us at commonemails@163.com.
