No guessing games, no scrolling through ten weather apps. Swipe the 7-day outlook for peak wind and wave height at a glance, then drill into hourly wind a full week out with gusts, true direction and Beaufort scale. The official NWS marine zone forecast comes straight from the source, written in plain English, free for every user. No subscription wall between you and the forecast that actually matters. See the whole picture on the chart. Toggle official NOAA ENC charts over Apple Maps for depth soundings, buoys and hazards at three detail levels, cached for when you lose signal offshore. Animated wind and current particle layers show you what's actually moving out there. Drag the time scrubber through the next 48 hours and watch conditions shift before you leave the dock. Tide stations are now plotted right on the chart. Tap any station for a 24-hour tide curve with the next high and low, so you can time the cut or the flat right. Have an AIS receiver aboard? Connect your boat's NMEA Wi-Fi gateway to see live depth, wind, water temperature and nearby vessel traffic on the chart, working offshore with no cell signal. Dropping the hook? Anchor Watch guards your position with a drag alarm and two-fix false-alarm protection, backed by Live Activity, Dynamic Island and Apple Watch alerts. Sleep easier. For the fishing crowd, sea surface temperature and current layers help you find the edges and breaks where fish stack up. SeaState is built for offshore anglers, cruisers, sailors, surfers and captains who want a straight answer, not a maybe. Download it and know before you go.

Verdict
The clearest difference is review sentiment: PredictWind at 84% against SeaState's 50%. PredictWind also leads on ratings volume (33K vs 3) and chart position (#22 vs unranked). SeaState's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PredictWind sells 16 in-app purchases, starting at $6.99 per month and SeaState sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
SeaState holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: PredictWind has 33K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 84% of PredictWind's written reviews are positive against 50% of SeaState's, so the app with the better star average is not the one people write more warmly about.
PredictWind ships an update every 11 days, SeaState every 2 weeks. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
