Memento Mori

How do we live a life of purpose?
We have an answer: Memento Mori, a clock that lets you see how many heartbeats you―and your loved ones―have left in your life. The idea is to imbue our lives with meaning by reminding ourselves of our mortality. Based on the hypothesis that we have a limited number of heartbeats in a lifetime, this app will let you do just that. How many more heartbeats do we have? What will we have accomplished, and where will we be when our heart beats their last?
