About this app

According to the rule of thumb in Japan, whistles help you survive after natural disasters such as Tsunamis and earthquakes. In particular, they will be beneficial in case that you cannot escape from collapsed buildings. However, it is not in practice to always hold a whistle for disasters that you cannot expect to occur. So, put it into your belongings, your smart phones. This will help you when accidents happen.

GPS location tag functions for when you're at the bar would be a great idea

I had the volume all the way up and it was not very loud. People farther than 10ft away would never hear it.
