Big Island Offline Guide also leads on in-app purchases (none vs 1) and ratings volume (20 vs 1). FaucetSafe's advantage is price ($2.99 vs $7.99) and rating (5.0 vs 4.8).

FaucetSafe costs $2.99 and Big Island Offline Guide $7.99 up front. FaucetSafe sells 1 in-app purchase, starting at $29.99 per year. Big Island Offline Guide asks for nothing beyond the download.

FaucetSafe holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Big Island Offline Guide has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 42% of FaucetSafe's written reviews are positive against 88% of Big Island Offline Guide's, so the app with the better star average is not the one people write more warmly about.
