# 21 Sharp vs Morse Code Complete

The clearest difference is ratings volume: Morse Code Complete at 85 against 21 Sharp's 1. Morse Code Complete also leads on iOS requirement (15.1 vs 17.0). 21 Sharp's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 21 Sharp sells 1 one-off in-app purchase and Morse Code Complete sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
