There is no notification when a message comes in. U have to be looking at the screen. It crashes constantly and has to be reloaded. We had 12 people trying to stay in communication about meals and excursions using this app, and it was completely hit or miss. You never knew. However, its your only choice on a princess cruise. Pick another cruise line or rate it low and maybe they will fix it.
