Journal Insights ranks your tags by how far a score moves on days you used them. This article explains the targets and metrics, the impact formula, which day each tag is matched to, and why a tag lands in Low Confidence.
Open it with the Journal Insights button at the bottom of the Journal screen. Titan runs the analysis on your iPhone from scores and tags stored in the app.
01Targets and metrics
The segmented control at the top picks a target. The Metric menu below it picks the score that target is measured against.
| Target | Metrics you can pick | Default |
|---|---|---|
| Recovery | Recovery Score, Stress Score, Resilience Score | Recovery Score |
| Sleep | Sleep Score, Sleep Debt | Sleep Score |
Switching the target resets the metric to that target's default. Each change reruns the analysis.
02The 60-day window
Every calculation covers 60 days, today included. The dates appear under the factor lists as "Window". Days with no stored score for the chosen metric drop out of the calculation. They count as neither tagged nor untagged.
03How impact is calculated
For each tag, Titan splits the days in the window that have a score into two groups. One group holds the days you tagged. The other holds every other scored day. Titan averages the score in each group.
Impact is the tagged average minus the untagged average, divided by the untagged average, times 100. The result shows as a whole percentage with a sign.
Suppose your Recovery Score averages 72 on untagged days and 63 on days tagged Alcohol. The difference is minus 9. Divided by 72, that is minus 12.5 percent, which displays as -13%.
A positive number means the metric was higher on tagged days. A negative number means it was lower. Titan colors positive numbers green and negative numbers red for every metric. For Stress Score and Sleep Debt, a higher number is the worse outcome, so a green +10% on Sleep Debt means more debt on tagged days.
A tag shows a dash in place of a percentage when none of its tagged days has a score, when no untagged day has a score, or when the untagged average is zero.
04Which day a tag is compared with
Titan compares a tag with the score stored for the same calendar day.
Your Sleep Score for a date covers the sleep you woke up from that morning. A late night on Monday, tagged on Monday, is compared with Monday's Sleep Score. That score comes from Sunday night, before the late night happened. The sleep that followed the late night is scored on Tuesday, and Tuesday is not tagged. Recovery, Stress, Resilience, and Sleep Debt follow the same same-day rule.
The Journal screen opens on yesterday under the heading "Tag What Happened Yesterday". Tags you add there go on yesterday's date. If you want a tag to line up with the score it could have affected, pick the date you woke up after it with the date picker at the top of the Journal screen. Stay consistent. Mixing both habits for one tag blurs its result.
05Occurrences and Low Confidence
The number in the grey capsule next to each tag is its occurrences, the count of distinct days in the window that carry the tag. A tagged day counts here even when it has no score.
Tags with 3 or more occurrences appear under Factors. Tags with fewer than 3 appear under Low Confidence, with the note that their impact may be noisy. Keep tagging and a factor moves up to the main list once it reaches 3 days in the window. A tag drops back down when older days roll out of the 60-day window.
06How factors are ranked
Both lists use the same order.
- Largest impact first, by size regardless of sign. A -15% ranks above a +9%.
- Tags with a dash come after every tag with a percentage.
- When impact ties, the tag with more occurrences comes first.
- Remaining ties sort alphabetically by tag name.
07Reading a factor row and the chart
Each row shows the tag, its occurrences, and its impact. The small line under the name plots the metric on the most recent 14 tagged days. The bar beside it fills left for negative impact and right for positive, and it reaches full length at 30 percent in either direction.
Tap a row to load it into the Impact Chart at the top. The first factor is selected when the screen opens. The chart draws one bar per scored day across the 60 days. Dark bars are days the tag was active. The green line marks the average on days without the tag.
08Impact is a correlation
Impact describes what happened to a score on days you tagged. It does not show that the tag caused the change. A tag that often lands on the same days as another habit, a hard training block, or illness will pick up their effect too. Use a strong result as a prompt to test the habit on purpose for a few weeks, then check whether the number holds.
