Memento Mori is an app meant to remind you to focus on the important things. It consists of an app and a widget which show you your exact age and how it is always increasing. Put it on your home screen and let it remind you every once in a while to be more mindful of what you actually want to do.
It is a reminder of the finitude of one's time on this earth. A tool to create meaning and urgency. An encouragement to use your time to the fullest.
Use every second you get as well as you can. Go!
