# Nautical Ship Flags vs Sailor's Deck

The clearest difference is review sentiment: Sailor's Deck at 100% against Nautical Ship Flags's 33%. Sailor's Deck also leads on rating (5.0 vs 4.6). Nautical Ship Flags's advantage is ratings volume (15 vs 1) and monetization model (free with in-app purchases vs paid). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Nautical Ship Flags sells 2 in-app purchases, starting at $0.99 per 7 days and Sailor's Deck sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sailor's Deck holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Nautical Ship Flags has 15 ratings behind it against 1, so its average is the more settled of the two.
