Hello there! This is Calculator Express. We are introducing you a beautifully designed app, that includes 6 handy tools: - Currency converter - Unit converter - Percentage calculator (hey marketers, this feature is for you) - BMI calculator - Tip calculator - World time converter (and many more tools will be added very soon, stay tuned!) You can customise Calculator Express as you wish - color, fonts, app icon, buttons background and even more! But what else? Guys, we think that calculation history is a very important feature and that's why we decided to make it more convenient - we added labels and notes to your calculations. Pin, copy and share. We think our app will be a great companion and just a handy simple tool. Privacy policy: https://calculator.express/assets/privacy.html Terms of Use: https://calculator.express/assets/terms.html

This is a calculator app using Reversed Polish Notation (RPN) In Portrait mode, this app provides a basic calculator with the four arithmetic disciplines +, -, x, and /. In Landscape mode, 30 extra buttons are available providing most functions found on a scientific calculator. You can do trigonometry, logarithms, roots, probability, and more. RPN is neat because you can do fancy calculations without having to worry about parenthesis. Putting the operator after the operands allow the operator to infer which are its operands without the clarification offered by paranthesis. The built-in help function (?) provides a short description of each function. The settings page allows you to set the number format, number of decimals displayed, decimal separator and more.
