See every page.

• Leading insight and strongest signal, each with its evidence one click away.
• Measures tiles: each is a 7-day median against your preceding 30 days, unless it says otherwise.
• This week vs last, from your recordings, plus your latest activity and your progress.
• A “How to read” panel sits right beside the tiles, so you never leave the page to learn what you are seeing.

Every tile carries its label — Recorded Calculated Estimate — and says higher or lower without labelling the direction good or bad.

• Ranges from 7 days to all of your history, or a custom window, with a baseline window you select.
• Smoothing as a trailing mean (7, 14 or 30 days) over faint raw points. Baselines, comparisons and CSV export always use the raw readings.
• Views: stacked, normalized overlay, before vs now, event-relative and phase comparison.
• Shaded gaps where there were no readings. A gap is missing data — never a value of zero, and never a line drawn through it.
• Flagged points can be left out of the baseline, and the chart says how many were excluded.

2D clinical by default, 3D when you want it.

• Trends, Compare, Activity and Journeys each offer an optional 3D view.
• 3D is a different way to look, not different data: the same baselines and the same labels apply.
• Switch between 2D Clinical and 3D Explore on the chart itself.

• Per-session pace, heart rate and cadence along the session, with run and walk bouts found from cadence and speed.
• Late-bout heart-rate response: the median recorded heart rate in the last 30 seconds of each bout. Heart rate trails a change of speed by around a minute, and the page says so.
• Effort distribution for the session, and a stated evidence level (good, limited or insufficient) for the recording itself.
• Optional 3D Explore and GEO route replay where a session has the data for it.

Where a treadmill session’s own pace could not be trusted, VITAL draws a reconstructed pace as a dashed line and labels it an estimate. Where evidence does not support a value, none is drawn.

• Play, restart, step and speed controls from 1× to 120×, with distance, pace and heart rate at the playhead.
• Where a session has no belt-measured distance, the race says its distance is the watch’s own estimate.
• The 3D terrain view states its source and accuracy: a 30 m surface model, about ±4 m vertical.

• Compare two or three sessions on one shared axis (elapsed time, moving time or distance), or set one session against its own history.
• Samples are drawn raw, with no smoothing, and gaps are left open. In 3D, depth is not a measurement.

• Before → now by body system: cardiovascular, autonomic, sleep and recovery, body composition. Each status is a recent-window comparison (the last 14 days against the reference period), not a verdict on your whole history.
• Dated notes on charts: click a chart to record what happened on that day.
• Recorded milestones and goals, with the sessions that supplied the evidence. REBUILD brings the physical-capability progress together.
• An optional 3D view of the same data.

The page is explicit: personal baselines describe independent lanes, and wearable progress does not establish medical recovery.

• Your usual range: the average of your latest 7 days against your own variation over the 60 days before. For weight and blood pressure, the latest 14 days against the 90 before.
• Every line is labelled Calculated and states which window it used.
• Sleep, Body Battery and body composition each have their own detail, shown against your own history.

“This is your own history, not a medical normal range.” Where there is not enough history to compare, VITAL shows the counts and no verdict.

• It uses the single longest continuous bout inside a session — intervals are never added together.
• The headline is the level you have demonstrated. Rest never lowers it. Only repeated, credible evidence can.
• Always shown with its Estimate label and a confidence level.
• The scale is published: for example 5 is a 200 m walk, 18 a 5 km walk, 50 a 3 km run, 65 a 5 km run, 100 a 10 km run in an hour or less.

VCI is not a statistical index, a clinical measure, a VO2 estimate, clearance or a prediction. It describes walk/run capacity only.
