Congratulations! give yourself a stamp! but wait... its missing trigonometry... yeah, TRIGONOMETRY IS MISSING!!!

I have been using this app for years. It was the best unit conversion app because it provides all kinds of unit conversion including the date function in that you can add and subtract from any date, or find the difference between two dates. Unfortunately since 2023, the calculator doesn't fit the screen when doing time/date, add/subtraction operations. I have submitted two feedbacks to the developer without seeing any bug fix on this issue. I am using iPhone 17 with iOS 26.2

I use this application every day to convert temperatures between Fahrenheit and Celsius, and I frequently use it to calculate the time between dates over long periods, especially how it relates to setting target dates. I love how easy it is to use. I also use it to do a lot of conversion of area and volume, for example, converting square miles into acres.
