Mareas es una aplicación que te permite consultar rápidamente las mareas en cualquiera de los puertos españoles. Rápidamente podrás consultar el estado de la marea (subiendo / bajando), la altura actual, e información sobre los coeficientes, próximas pleamar y bajamar. La aplicación funciona de forma offline, por lo que no necesitarás conexión a internet en ningún momento. Mareas ofrece widgets para la pantalla de inicio y la pantalla de bloqueo para que puedas consultar en todo momento el estado de la marea sin necesidad de abrir la aplicación, así como una versión para Apple Watch. También podrás consultar a Siri el estado y altura de la marea y te dará la respuesta. ** Los datos de la aplicación son los proporcionados de forma pública por el Instituto Hidrográfico de la Marina, publicados en el Anuario de Mareas del año en curso. **
Seander

Seander helps you decide where to anchor and when to go, with a clear read of marine weather tailored to each anchorage — not just a generic forecast for the area. Check marine forecasts, explore Mediterranean anchorages, save your spots, and get a quick interpretation so you can sail with more judgement and confidence. What you can do with Seander: • View wind, swell and the day’s evolution, with a full forecast expandable from Home. • See each anchorage’s status (comfortable, fair or rough) based on wind, sea state and shelter protection. • Explore anchorages and harbours on the map, with detail sheets, comfort timeline and shelter rose. • Ask Seander Advisor in plain language: should I stay here?, where should I anchor?, how’s the weather evolving? • Save favourite locations and see top picks nearby when conditions allow. • Use the app in light or dark mode, built for daytime checks and night watches on board. Seander is built for skippers, crews and sailing enthusiasts who want useful, direct, actionable information — less noise, more judgement before you leave.

Verdict
The clearest difference is in-app purchases: Mareas at none against Seander's 2. Mareas also leads on device support (4 vs 2). Seander's advantage is update cadence (every 10 days vs every 3 months). On price, ads and iOS requirement there is nothing between them.
