Insights compares the days you did something with the days you did not, over your last 90 days, and shows how your Sleep score, Readiness score and your own 1 to 5 ratings differ between them. Each item needs at least five days with it and five days without it before NOYU will estimate a difference.

What it compares with
Choose what to compare with using the tabs under the header:
- Sleep and Readiness, the scores NOYU works out from your wearable. An answer for Tuesday is compared with Tuesday night's sleep and the Readiness you wake up with on Wednesday.
- Each 1 to 5 rating on your Journal, such as Energy, Mood or Stress, once you have rated it at least once in the window. An answer for Tuesday is compared with how you rated it on Tuesday, the way mood trackers compare a mood with that day's activities. If you rated it more than once that day, NOYU uses the average. Night items, such as a late meal or a screen in bed, come after the day's rating, so they are only compared with Sleep and Readiness.
Insights does not compare with other metrics, such as HRV or Strain.
What it compares
Yes or No items. A day you answered Yes is a day with it. A day you answered No is a day without it.
None, Some or Lots items, such as caffeine and alcohol. Some and Lots count as with it; None counts as without it. If you count drinks, any number above 0 is a day with it and 0 is a day without it.
Automatic items, which NOYU fills from your wearable: daily steps, cardio minutes, strength minutes and time in heart rate zone 2. A day counts as with it when it reaches the target in the item's name, such as 7,000+ steps or 30+ min of cardio. Cardio and strength come from your recorded workouts, including strength sessions you log in NOYU, so a day your wearable synced with no workout counts as a day without.
You can change an automatic item's target when you edit your Journal. The new target applies to the whole 90 days straight away, so changing cardio from 30 to 60 minutes reclassifies your existing days against 60 minutes. Your Journal entries are not changed.
Ratings themselves are not compared as things you do, and neither are notes.
Days NOYU leaves out
A day you did not answer is left out, never counted as a No.
Occasional items are the exception. On any day you logged something else in your Journal, an occasional item you did not tap counts as a day without it. This only applies from the day the item became occasional. That is how a sauna you only tap twice a week still gets its days without.
A day only counts if it also has the thing being compared: a Sleep score for the Sleep tab, or a rating that day for a rating tab. So the same item can have enough days on one tab and not another.
How to read a result
Each result shows how many days it is based on, such as 14 days with · 23 without. Tap a result to see that item's days in Summary.
The number is NOYU's current estimate of the difference. For Sleep and Readiness, it is the percentage difference between your average score on days with the item and days without it, such as +6%. For a rating, it is the difference in points on your 1 to 5 scale, such as +0.8.
The faint range around it is a 90% uncertainty range. If it crosses the middle, your data so far could support a higher result, a lower one or no real difference.
Colour shows the better direction. Green is better and red is worse. For ratings such as Stress and Pain, lower counts as better.
Patterns, No real difference, Some early signs and Needs more days
Results are grouped into four sections.
Patterns are items where NOYU can call a direction. That needs all three: a difference of more than 3% either way (for a rating, 3% of your average rating on days without it), a range that stays on one side of the middle, and a result that still holds after NOYU checks all your items together. The last check is there because comparing many items at once makes it likely one looks different by chance.
No real difference is an answer too: the whole range sits within 3% either side of no difference.
Some early signs holds everything else with enough days. The number shows which way it leans so far, but it could still go either way, and more days usually narrow the range.
Needs more days lists items without five days with it and five without it yet, counting each towards five, such as 4 of 5 days with · 1 of 5 without. An item you have done every day so far says so, because it needs some days without it before NOYU can compare. Five is enough to make an estimate, not a guarantee of a clear answer.
Why the last 90 days
The window keeps the comparison close to your current routine while still giving NOYU enough days to find a pattern. Each new day replaces the oldest one, so results can change as old days drop out.
What a pattern is not
A pattern in your own data is an association, not proof of a cause. If late meals tend to happen on stressful evenings, stress could explain some or all of a lower Sleep score on those nights. Same-day ratings have a second catch: a good mood could prompt a walk as much as the walk lifts your mood.
A strong pattern is a good reason to run an experiment: change one thing deliberately for a fixed window and see what moves. See How experiments work.
