Pascal vs Dev Calc
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: Dev Calc at Free against Pascal's $2.99. Dev Calc also leads on iOS requirement (13.0 vs 17.6). Pascal's advantage is rating (4.0 vs 2.0) and ads (none vs shown). On in-app purchases, monetization model and device support there is nothing between them.

Dev Calc is free to download; Pascal costs $2.99 up front. Pascal sells 3 one-off in-app purchases and Dev Calc sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Pascal holds the better App Store score, 4.0 against 2.0. That said, the two scores are not equally well evidenced: Pascal has 23 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 68% of Pascal's written reviews are positive against 60% of Dev Calc's.
Pascal ships an update every 2 weeks, Dev Calc every 2 months. The most recent releases landed on October 5, 2026 and October 7, 2026 respectively.
