Verdict

The call

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.
