Callcalc: Smart Calculator para Android

Callcalc: Smart Calculator is a utility application designed to facilitate quick arithmetic calculations during phone calls. This app features a floating calculator that overlays the call interface, allowing users to perform essential calculations without the need to switch between applications. It supports basic arithmetic functions such as addition, subtraction, multiplication, and division, and also includes a calculation history for easy reference. The app can launch automatically at the start of a call or immediately after it ends, making it particularly useful for professionals who need to handle figures in real-time during conversations.

The calculator operates offline and is designed to have a minimal impact on device performance, ensuring smooth functionality while calls are in progress. Users can customize the interface with different themes and adjust the size of the floating window to fit their preferences. While the app is accessible to non-technical users, it requires certain permissions to function effectively, including the ability to draw over other apps and detect phone state changes. This makes it a practical tool for those in roles such as sales, logistics, or advisory services, where quick calculations are often necessary.
