Survivor for Android
Determine how many more years you and your friends are going to Survive using the power of Statistics.
"Eww Statistics!" you say, well we all hate it [*] but you will have to admit it can be useful in some limited situations beyond passing another boring Statistics exam.
In this application you give us the birthday and gender for a person and we will give you estimate of how many more years they have left. Obviously we are making some assumptions here but we are presenting a reasonable on-average estimate for life expectancy [**].
* FIND out how far into the future you will survive ("We'll be on Mars by 2030.. right?")
* SHARE how many years you have left via Twitter, Google+ and more
* TRACK the life expectancy of your family for fun
[*] Other Mathematical disciplines: we still cool though *fistbump*
[**] *grumble* you win this round statistics
Note: You will probably live longer than the estimate because you are a) Too Smart b) Too Good Looking and c) Modern medical science has our collective backs.
