# Nmap Guide vs Learn Cryptography

The clearest difference is rating: Learn Cryptography at 5.0 against Nmap Guide's 4.2. Learn Cryptography also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (15.1 vs 17.2). Nmap Guide's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Nmap Guide sells 1 one-off in-app purchase and Learn Cryptography sells 4 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Learn Cryptography holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Nmap Guide has 5 ratings behind it against 1, so its average is the more settled of the two.

Nmap Guide ships an update every 2 months, Learn Cryptography every 3 weeks. The most recent releases landed on October 13, 2026 and October 24, 2026 respectively.
