Rivage is a maritime app for tracking tides, wind, waves and weather at your favorite coastal spots.

The app shows the current tide height, the time and coefficient of the next high or low tide, the full 24-hour tide curve, wind (speed, gusts, direction), temperature, and sea state (wave height, period, swell). Add as many coastal cities as you want to your favorites, or use your device's location to see your current position.

— FEATURES —
• Tides: full curve, next high / low tide, real-time height, SHOM coefficient
• Weather: temperature, weather code, hourly forecast
• Wind: speed, gusts, direction, visual heading indicator
• Sea: wave height, period, direction, swell
• Activity scores: fishing, surf, kite (computed from current conditions)
• Day-by-day detail view, interactive curve with per-cycle coefficient
• Search coastal cities and nearby harbors
• Home-screen widget: tide and sparkline at a glance
• Themes (Ocean, Sunset, Forest), light / dark / system mode

— WHO IT'S FOR —
Rivage is built for coastal fishermen, surfers, windsurfers and kitesurfers, sailors, free-divers, and anyone who wants to know what the shore looks like before heading out.

— PRIVACY —
Your location is never sent to a Rivage server — there is no Rivage server. Coordinates are only used on-device to call public tide and weather APIs. No account, no email, no sign-in required. See the privacy policy for details about the quality monitoring tools used.

— DATA SOURCES —
Forecasts come from open public services: Open-Meteo (tides, wind, weather), Overpass and Nominatim on OpenStreetMap (search and nearby cities). All requests originate from your phone over HTTPS.
