Calculators

Time together lasts only while both of you are alive, so Leftover counts up to whichever life is expected to end first. Your side comes from the default number on the Life Expectancy screen, and the other person's from the Birthday and Life expectancy (years) you type in.

Yes. It is the same form, and all it needs is the animal's birthday and how long it is likely to live.

max is the total for the most time you put in, min for the least, and avg sits halfway between them. Without a minimum the result has a single number.

With Days as the unit, every day you spend together counts as all 24 of its hours, so the totals run much higher, and the note says as much. For time you really share, Hours or Minutes give a truer picture.

The birthday and the life expectancy you entered add up to a date that is already behind. Check both fields, since a typo in the year is the usual reason.

No. The figure is the gross time across the days you overlap, so it is worth counting only the hours you actually spend together.

Yes. The button with two arrows at the top of a calculator switches between the steps and a single page with every field and the result, and each calculator remembers which one you chose. 24h has no such button, because its whole day already sits on one screen.

You can tap Skip when the calculator asks at the start. Save asks again, and there a name is needed, because it is how the calculation shows up in its list.

Wasted looks back at a stretch of the past between two dates and lets you weigh those hours with factors such as how much you enjoyed them. Basic counts anything that repeats, over a round number of years or between two dates, and stops at the plain total, which makes it the one to reach for when the only question is how much. Add up what a habit has taken and See what a routine adds up to walk through each of them.

No. The whole third step can be skipped, and the result is then a plain count of hours. A factor you leave empty, or set to its middle level such as Neutral, does not move the total.

Choose its middle level, Neutral for enjoyment, and the factor stops moving the total. In the steps, Clear under the list only closes it and keeps the level you chose, while on the single page it empties the factor.

One calculation holds one habit. For a second one, start another calculation with the round + button, and both wait in Wasted calculations under the day you saved them.

Wasted adds up time that has already gone, so both dates stop at today. For the years ahead, Basic can run the same habit across as many years as you choose.

It takes the daily average of everything you have logged as wasted in Time Entry, stretches it across the dates of the calculation and sets each total halfway between that figure and your estimate.

The calculator found no wasted time in your diary, and only entries on a wasted topic count toward the average. The average is read when the calculator opens, so an entry you add while it is open counts the next time you open it.

Usually not. The average covers every wasted activity at once, so it pulls in hours that have nothing to do with the habit, and the result says more about your days in general than about the habit itself.

No. The calculator counts all your wasted entries, whatever filter Time Entry has on at the moment.

A day's share is easiest to read off a clock, such as 01:30, so Day opens the hour and minute wheels. A week holds more than a clock face shows, so Week takes a plain number of hours, up to 168. Switching Time unit for input clears the time you entered, which is why it pays to choose the unit first.

Yes. Calculate for specific date range on the second step swaps the period for a Start date and an End date, both days counted, and either of them can lie in the future, as far ahead as the end of 2199.

It opens Basic in a window over the topic, for working out how many hours an activity took before you started logging it. The window has no name and no Save, and the total goes into Starting hours once you type it there yourself, as Add hours you spent before shows.

A day holds 24 hours, so a block longer than what total left shows is turned away with "That would take the day past 24 hours. Something already in it has to give first." Shorten or remove another block first and add the new one again, since the block window does not keep what you typed.

Tap the block to change its name or time, or to remove it with the bin at the top of its window, which asks "Are you sure?" first. A swipe to the side removes a block at once, with no question.

24h holds one day at a time. For a week that is not the same every day, save a few days under their own names, such as a weekday and a Saturday, and they wait side by side in 24h calculations.

It depends on what you already know. With the hours and the due date in hand, Quota tells you what each day, week or month asks. If you know the hours and how much you can give a day, Deadline finds the date it lands on, and with a daily pace and two dates, Total Time adds the hours up.

A quota reads like a clock, so 05:30 means five and a half hours. The minutes are rounded up, which can add one to an uneven figure, and 5.77 hours shows as 05:47.

The dates are too close for the hours you gave, so the quota would need more than a day, a week or a month can hold. The result still shows, and moving End date further out or lowering the hours brings it back within reach.

No. It opens Planning in a window over the topic and works the number out, and the goal changes only once you type that number into it and tap Save on the topic.

From today, the moment the calculation is opened, so a saved calculation shows later dates when you open it again a week on, while its row in the list keeps the dates of the day it was saved.

max comes from the most hours at the slower pace, so it is the latest the goal is likely to be done, and min comes from the fewest hours at the faster pace, the earliest. avg sits between the two.

Both spread a daily time across two dates, both days counted. Total Time keeps the question inside Planning, next to the other questions about a goal, while Basic also takes a weekly time or a round number of years, as See what a routine adds up to shows.

Each calculator keeps its own list, which opens when you tap its card on the Calculators screen, and the round + at the bottom of that list starts a new calculation. The list is grouped by the day each calculation was last saved, the most recent day first.

The list is grouped by the day a calculation was last saved, so a change saved today moves it under today's date, above the ones you have not touched since.

No. A change is kept only after Save and the Name window, and leaving the calculation with the back arrow drops it without a question.

No. The app asks "Are you sure?" before it deletes anything, and after Yes the calculation is gone from its list for good.

Leftover counts the time you have left together from the day it was worked out, so a saved figure runs a little high with every day after it. An open count already shows today's figures, while its row in the list keeps the ones from the day it was saved until you recalculate it.

Yes. It counts your side from your default life expectancy as it is now, so a changed number on the Life Expectancy screen shows up in every count you recalculate.

Behind the question mark at the top right of every calculator. The helper that opens has Select example with the examples of that calculator, and in Leftover it appears once your own life expectancy is set.

An example stays an example, and while it is on screen the calculator shows "This is example data" where Save would be. The red round arrow at the top clears it, and a calculation you fill in yourself can be saved as usual.

Clearing empties the fields and leaves the name, so a calculation of your own would be saved under the name of the example. Tap the name at the top to change it before you save.
