Standard units of time like seconds, hours, days, months, and years chop up time into chunks that seem sensible.

But here’s an experiment: What if you were to measure the time of your life in other, very different units? Does life feel shorter? Longer? More absurd? More precious?
Now’s the time to find out.

Enter your birthdate—then confront the not-so-grim reaper as you find out just how much you have (left) to live for.

How many cat lifetimes until you die? How many blue moons? How much space junk has fallen to earth since you were born, and how many breaths have you taken?

Far more than a mere lifespan calculator, this illustrated journey explores the metrics, mileposts, and meaning of life’s span. Carpe diem!

Too big in size.

As we all know that iPhones do not have external memory option, so we are always under a limitation. But this app, which tells some information which is purely some calculations and some facts acquires upto 300Mb alone. I say that's not worth it. Yeah the information you provide is good, but useless in daily-rushing life at the same time. I don't know whether the makers of these app are a firm or a group of coders. If this was your first app, I would appreciate your work and suggest to optimise size, but if it wasn't your first app, you have a long run to go. Thank you for the app. And thanks for reading. Have a good day. :)
