SeismicAR es una aplicación educativa en la que podrás observar en tres dimensiones las diferentes capas del interior de la Tierra y las características de propagación de las ondas sísmicas P y S a través de ellas, mediante Realidad Aumentada. La aplicación se distribuye con un track, de manera que, apuntando con la cámara del dispositivo al citado track, se proyecta la imagen tridimensional de un corte de la Tierra en el que se distinguen las diferentes capas terrestres que la componen según el modelo geoquímico, así como las trayectorias y velocidades que siguen las ondas sísmicas P y S al atravesar cada capa. Al hacer click sobre cada uno de los dos tipos de ondas sísmicas se muestra información útil sobre las mismas. Esta aplicación ha sido desarrollada en colaboración con la Universidad Camilo José Cela (UCJC).

The clearest difference is in-app purchases: Seismic_AR at none against Periodic Table's 3. Seismic_AR also leads on iOS requirement (11.0 vs 15.0). On price, ads and device support there is nothing between them.
