The app developer was a high school teacher until recently and noticed that the iPads introduced for students in high schools didn't have a built-in calculator. Upon downloading a calculator app from the store, they encountered issues such as intrusive ads and poor usability. Motivated by the desire for a reliable and user-friendly calculator app, they created this application. It is not driven by profit but rather aims to be useful for many people, including those who face similar challenges.
