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.
21 Sharp holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Morse Code Complete has 85 ratings behind it against 1, so its average is the more settled of the two.
