Pascal
This app offers a powerful 3-in-1 calculator experience, combining scientific, graphing, and programmer functionalities. The scientific calculator is free, while graphing and programmer modes require an in-app purchase, with trials available for testing.
- Scientific calculator (degree, radian, gradian modes)
- RPN mode
- Graphing calculator with smart tape and adaptive sampling
- Programmer calculator (8, 16, 32, 64-bit bitwise)
- Multiple numeral systems (binary, octal, decimal, hex)
- Unicode and ASCII character encoding

Pascal (formerly Calculator³) is a professional-grade 3-in-1 scientific, graphing and programmer calculator. Scientific Calculator¹ - Supports degree, radian and gradian modes - Decimal factorials - Modulo operator - Permutations (nPr) and combinations (nCr) - Standard memory functions - RPN mode Graphing Calculator² - Includes all functions the scientific calculator offers - TI-like design - Perform calculations on a smart tape (i.e. no need to close parenthesis, multiply out brackets, real-time syntax highlighting) - Plot graphs using adaptive sampling algorithm to generate precise results - Show or hide roots/intersections and trace values Programmer Calculator³ - Supports 8, 16, 32, and 64-bit bitwise calculations - Binary (base-2), octal (base-8), decimal (base-10), and hexadecimal (base-16) numeral systems too - Unicode (UTF-16) and ASCII character encoding - A binary table that shows you in real time the binary representation of the current operand - RPN mode

Verdict
The clearest difference is price: Evaluate at Free against Pascal's $2.99. Evaluate also leads on iOS requirement (9.0 vs 17.6). Pascal's advantage is update cadence (every 2 weeks vs every 11 months) and review sentiment (68% vs 44%). On rating, ratings volume, ads and in-app purchases there is nothing between them.
