Verdict

The call

The clearest difference is price: Calculus at Free against C++ Q&A's $0.99. Calculus also leads on ads (none vs shown) and update cadence (every 16 months vs every 39 months). C++ Q&A's advantage is in-app purchases (none vs 13) and iOS requirement (13.0 vs 15.0). On device support there is nothing between them.
