This calculator uses postfix notation (also know as Reverse Polish notation). If you have ever used an RPN calculator (such as a classic HP calculator), you will not want to switch back. For those not familiar with RPN: enter the operands first, then select the operation. Operands are pushed on a stack and removed when applying an operation. Results are pushed back on the stack, ready for the next operation.

Various numbers styles can be selected (regular floating point, scientific notation, engineering notation).

This is a standalone watch app and does not require your iPhone to be nearby.
