# Karel1981 vs C++ Compiler

The clearest difference is rating: Karel1981 at 4.5 against C++ Compiler's 2.2. Karel1981 also leads on iOS requirement (9.0 vs 13.0). C++ Compiler's advantage is ratings volume (25 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Karel1981 holds the better App Store score, 4.5 against 2.2. That said, the two scores are not equally well evidenced: C++ Compiler has 25 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Karel1981's written reviews are positive against 70% of C++ Compiler's, so the app with the better star average is not the one people write more warmly about.

Karel1981 ships an update every 5 months, C++ Compiler every 6 months. The most recent releases landed on October 2, 2026 and October 12, 2026 respectively.
