# Rain Alerts vs SwellMap Boat

The clearest difference is rating: SwellMap Boat at 4.6 against Rain Alerts's 3.0. SwellMap Boat also leads on ratings volume (11 vs 2). Rain Alerts's advantage is ads (none vs shown) and iOS requirement (10.0 vs 14.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Rain Alerts sells 1 one-off in-app purchase and SwellMap Boat sells 1 in-app purchase, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.

SwellMap Boat holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: SwellMap Boat has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 41% of Rain Alerts's written reviews are positive against 34% of SwellMap Boat's, so the app with the better star average is not the one people write more warmly about.

Rain Alerts ships an update every 2 months, SwellMap Boat every 3 months. Both last shipped on November 1, 2026.
