Revision #1058

'''Trends is Loopa reading your own data back to you.''' Not a wall of charts. The handful of things that have actually changed, and what each one still needs before it can say more.

You will find it under '''Health''', then '''Trends'''.

== Worth knowing right now ==

The top of the screen carries three to five things, picked because they are unusual '''for you'''. Loopa compares the last week against your own previous eight weeks, so "your fiber is running higher than usual" means higher than '''your''' usual, not higher than a stranger's average. That matters if your targets are unusual for good reasons.

Milestones land here too: a longest-ever logging streak, a goal reached, the lowest trend weight in a month, a first full week on a new medication.

If you dismiss one, it stays gone for two weeks.

== Every number says how solid it is ==

Under each figure you will see how many '''fully logged days''' it used. A day counts as fully logged when you recorded three or more meals.

'''Half-logged days are never averaged in.''' If you logged one meal on Tuesday, Tuesday is not a 400-calorie day. It is a day you did not finish logging, and averaging it would quietly pull every figure down. Those days are counted and shown separately instead.

Days with nothing at all are counted as unlogged, never as zero. The header tells you the split: so many fully logged, so many partial, so many unlogged.

== When a trend does not have enough yet ==

It tells you what it needs, in words, instead of showing you a number.

* '''Log 2 more full days to see your 7-day average.'''
* '''Weigh in across at least a week so the trend has something to smooth.'''
* '''Add your date of birth and sex in your profile so nutrient targets can be matched to you.'''

That is deliberate. A weekly average built from two days is a number that is wrong in a direction you cannot see, and we would rather tell you what is missing than hand you one.

== Choosing what appears ==

'''You can switch off any section you do not use.''' Go to '''You → Preferences → Customize
Trends''' and turn off the ones you scroll past. What is left keeps its order, and your
choices are saved to your account, so the page looks the same on every device you sign in on.

'''A hidden section is not fetched.''' Loopa stops asking for the data behind a section you
have switched off, so the page loads lighter as well as shorter.

'''A new section arrives switched on.''' When a chart is added it appears for everybody,
including members who have already customized the page, and you can turn it off if it is not
for you.

'''Turn everything off''' and the page tells you so, with a button straight back to the
settings.

Customizing Trends is part of [[subscription-and-the-full-dossier|Loopa Premium]]. Every
section is listed either way, so you can see what is there before you decide.

== The same page on both phones ==

Trends carries the same sections in the same order on iPhone and on Android, and each chart
sits under the section it belongs to (your vitals together, your macros together) rather
than in one long list.

Each chart is named the same on both. The 1–5 check-in you log as '''Feeling''' is charted as
'''Feeling'''; body fat reads the same wherever it appears.

== What is in there ==

* '''Intake'''. Rolling averages for calories and each macro, weekdays against weekends, and how your calories spread across your meals.
* '''Nutrients'''. How your intake compares with the reference for your age and sex.
* '''Weight'''. A smoothed trend line with your actual weigh-ins still visible, your rate of change over the last two and four weeks, and how far you are from your goal. If you are moving toward it, Loopa gives a projected '''range''' rather than a date, and says out loud that it assumes your current rate continues.
* '''Energy balance'''. An estimate of what you burn against what you logged eating, weekly. Labeled an estimate everywhere it appears, because it is one.
* '''Fasting, hydration and activity'''. Completion rate, average window, weekly totals.
* '''Medication and supplement adherence'''. Doses logged against doses expected, and any gap of two days or more. This counts doses you '''logged''', which is not the same as doses you took.
* '''Consistency'''. Your streak, days logged per week, and the day of the week you most often miss. That last one is usually the single most useful thing on the screen.

== Patterns in your own data ==

Further down, Loopa compares two of your own signals against each other: weekly weight change against how much you logged eating, fasting consistency against weight change, protein on training days against rest days, and sodium against the next morning on the scale.

'''These are patterns, not causes.''' They come from your own logs, with no control group and no way to rule out everything else going on in your life. Loopa says so on every one of them, and it will not show you any of them until you have six weeks with at least four full days in each, because a pattern drawn from a fortnight can point the wrong way entirely.

== Where the reference numbers come from ==

Nutrient targets are the '''Dietary Reference Intakes''' published by the National Academies of Sciences, Engineering, and Medicine, banded by age and sex, with the FDA Daily Values used for saturated fat, added sugars and cholesterol. The weight trend uses an exponentially weighted moving average. The expenditure estimate uses the Mifflin-St Jeor equation. Each figure names its source on screen.

Loopa is wellness tracking. It is not medical advice, and none of this replaces your clinician.
