Wastime
Life expectancy
Your own guess and the average where you live are the two easy ways to put a number on how long a life might last, and the calculator adds a third that takes your habits into account. None of them can say how much time you really have, though any of them gives the calendars and the calculators something honest to count from.
These guides go through the calculator, the results it keeps and the choice of which number the rest of the app uses by default.

Questions and answers
Where does the calculator's number come from?
It starts from a baseline made of three numbers, the average of your countries for your sex, a fixed 85 years and your own number, and your answers then move the years still ahead of you up or down. It is a rough estimate meant to give you something to think about, which is also what the disclaimer before each assessment says.
Where do my answers go?
Nowhere outside your phone. As the disclaimer puts it, "Your answers and the result are calculated and stored on this device", and the calculator doesn't ask for an account. What the app may report about itself is up to you, as Choose what the app may report shows.
Why do I get a range rather than one number?
The calculator takes two and a half percent of the estimate either way, so the range is a reminder of how rough the number is. It doesn't measure how likely each end of it is.
If I change my birthday or my countries, does an old result change too?
No. A result keeps the data it was calculated from, and Show details on its screen shows them. For an estimate that takes your new data into account, run the calculator again, and the new result is saved next to the old one.
Does Update keep the old number somewhere?
No, Update writes the new answers over the result. If you want to compare one year with the next, run the calculator again instead, and both results stay in Results.
How many results can I keep?
As many as you like. Each run of the calculator is saved as a separate line in Results, and one of them can be the default.
Why is an option in Life Expectancy Settings gray?
There is nothing for it to count from yet. Countries needs at least one country, Custom needs your own number, and Calculator needs at least one saved result.
Does the default change my calendars?
No. The calendars and the life timer count from the Life Expectancy type on the Calendars screen, which has a choice of its own, so you can keep them on your own number while the rest of the app counts from a result. The source Calculator is called Calculations there.
Why has the gear on the Life expectancy screen turned red?
A source has appeared that Life Expectancy Settings hasn't shown you yet, such as your first saved result, so it may be worth choosing again. The gear goes back to its usual color once you open the window.
