This app is a countdown app until the birthday. That celebrates his birthday every year, so feel very early, I made the time to visualize.
Is not only the time until the birthday of watch, you can also see their life. This is up to the average life expectancy of Japanese people, it is their remaining time. (Men 81 years of age, is the calculation of the 87-year-old woman)
By the way I am, it seems not only live about 17700 days left. Or, sad. .
