Pascal vs Computer Science Calculations
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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

Verdict
The clearest difference is price: Computer Science Calculations at Free against Pascal's $2.99. Computer Science Calculations also leads on iOS requirement (15.0 vs 17.6). Pascal's advantage is ads (none vs shown) and update cadence (every 2 weeks vs monthly). On in-app purchases and device support there is nothing between them.
