PiSquared vs Sum List

PiSquared is an RPN-only calculator for the Apple Watch. It supports a wide variety of mathematical and scientific functions as well as binary operations for programmers. Integer, floating point (real) and complex numbers are equally supported. These functions are available: - calculation of the number of combinations or permutations for integer numbers - factorials for integer numbers or Gamma function for positive non-integer numbers - trigonometric, logarithmic, exponential and hyperbolic functions for floating point and complex numbers - date and time conversions - logical operations for binary, octal or hexadecimal numbers - cartesian to polar coordinate conversions and vice versa (floating point numbers) - degrees to radians and vice versa conversions (floating point numbers) - absolute, integer and fractional value of a number (floating point and partially complex numbers) - rounding of a real number (standard rounding and rounding up or down) - random number generator and some more. The calculator has a stack depth of ten and features ten additional storage registers. All storage registers and the stack can be inspected. The stack itself can be manipulated by moving it up or down or by swapping its two topmost elements.

Create lists with quantities, calculate the sum: - Simple table for budget or any similar calculation. - User can choose a currency, measurement or custom unit - Marking of completed items is possible. Folder structure for easy organizing - On device folders are used for storing lists. - Lists can be created in a folder or without a folder. - Lists can be duplicated, moved or deleted. - Deleted lists can be recovered from Recently Deleted folder. - iCloud folders enabled in-app-purchases. - iCloud folders are private, and can be accessed by only the user. They can be accessed by only the devices using the same Apple ID. List structure - Contains rows - Each row is formed of a title and and a multiplication of two quantities. - Rows can be marked as complete. List has a title and notes section. - Title can be edited. - Notes about the list can be entered. Notes can be shown or hidden. - Decimal places shown is 2 by default, but can be adjusted. - Calculations can be hid, only title and a value can be shown at each row for simplicity. - At the bottom, the sum of all list items is shown. - The sum can be copied to clipboard. - The list can be exported as a CSV file in the share menu.
