# Smart Waters vs Doyle Guides

The clearest difference is rating: Smart Waters at 5.0 against Doyle Guides's 4.3. Smart Waters also leads on in-app purchases (none vs 18) and update cadence (every 10 days vs every 5 weeks). Doyle Guides's advantage is review sentiment (60% vs 25%) and ratings volume (50 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Doyle Guides sells 18 in-app purchases, starting at $9.99 per month. Smart Waters asks for nothing beyond the download.

Smart Waters holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Doyle Guides has 50 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Smart Waters's written reviews are positive against 60% of Doyle Guides's, so the app with the better star average is not the one people write more warmly about.

Smart Waters ships an update every 10 days, Doyle Guides every 5 weeks. The most recent releases landed on October 9, 2026 and October 10, 2026 respectively.
