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. **

Verdict
The clearest difference is in-app purchases: Mareas at none against My Tides's 2. Mareas also leads on iOS requirement (15.0 vs 18.0). My Tides's advantage is update cadence (every 3 days vs every 3 months). On price, ads and device support there is nothing between them.
