PredictWind — Marine Forecasts

What it does

PredictWind is a professional-grade marine weather forecasting application designed for sailors, boaters, and anyone whose activities depend on accurate wind and sea conditions. The app provides highly detailed weather data through an interactive map interface, allowing users to visualize wind, waves, rain, and other meteorological data. Its core strength lies in aggregating and presenting data from multiple world-leading forecast models, giving users the power to compare predictions and make more informed decisions.

Where it shines

PredictWind excels in delivering dense, technical data in a highly usable format. The centerpiece is the animated wind map (01:35), where particle animations beautifully illustrate wind speed and direction, making complex data intuitive. The app truly shines for its power-user features, such as the ability to seamlessly switch between six different forecast models (01:50) to compare data sources. Furthermore, it transforms the map into a practical tool, as seen with the distance measurement feature at 05:11, which allows for direct route planning within the app.

UX highlights

Multi-model comparison. Users can overlay or switch between forecasts from sources like GFS and ECMWF in tables (03:13) and graphs (03:38), offering a level of professional analysis rarely seen in consumer apps.
Interactive map tools. Features like the 'Measure Distance' tool (05:12) turn the map from a passive display into a functional planning workspace.
Data-rich pop-ups. Tapping anywhere on the map brings up a detailed card with precise data points like wind speed, direction, and latitude/longitude (01:46), providing immediate, granular information.
Layered information hierarchy. The side menu (02:31) provides clear access to different views like Daily Briefing, Tables, and various map types, allowing users to drill down into the data they need.
Clear forecast options. A simple pop-up (01:51) gives users direct control over the forecast model, resolution, and display style without navigating deep into settings menus.
Efficient onboarding. The app gets users into the core experience quickly with a straightforward registration (00:06) followed by an immediate, mandatory location setup (00:57).

Monetization & growth

Monetization is handled through a freemium model with contextual paywalls. While much of the core functionality is available for free, advanced features like 'Gust Maps' (04:11) and 'CAPE Maps' (04:27) are locked. When a user attempts to access these, a screen appears explaining the benefits and prompting them to upgrade. The main subscription page (04:20) presents three plans (1, 3, and 12 months) with clear discounts for longer commitments, a common strategy to increase lifetime value.

Who it’s for

This app is clearly built for a niche but serious audience. Its target users are experienced sailors, professional mariners, competitive racers, and dedicated hobbyists who require reliable and detailed weather forecasts for safety and performance. The emphasis on comparing different models and using planning tools suggests it's for users who are not just consuming weather information, but actively analyzing it to make critical decisions on the water.

Notes & opportunities

The app's greatest strength, its data density, could also be a point of friction for novices. The onboarding is fast but offers little guidance on how to interpret the various models or use the advanced tools. Adding optional, bite-sized tutorials or tooltips on first use could broaden its appeal. Additionally, while the contextual paywalls are effective, the value proposition could be strengthened with a short free trial for premium features to let users experience their power before committing.
