# Calculus vs 船员海员考试题库

The clearest difference is iOS requirement: 船员海员考试题库 at 13.0 against Calculus's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Calculus sells 4 in-app purchases, starting at $1.99 per month and 船员海员考试题库 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
