SuperAge calculates biological age as a multi-signal estimate, not from one raw metric.
The exact weighting can evolve as the model improves, but the core idea stays the same: combine useful patterns from recent health data to estimate how your body appears to be functioning relative to your chronological age.
What goes into the estimate
SuperAge looks for patterns across several types of input, including:
- recovery-related signals
- cardiovascular signals
- activity and movement data
- sleep-related signals
- overall data coverage across the available evidence
The estimate is stronger when these signals are present in a reasonably complete and recent form. It is weaker when the evidence is sparse, stale, or uneven.
What makes the estimate stronger
The estimate is usually more useful when:
- Apple Health contains enough relevant data
- the data is recent, not weeks out of date
- the signals are consistent enough to show a pattern
- SuperAge has broad coverage instead of just one or two isolated metrics
Completeness and recency matter. If important inputs are missing, delayed, or only partially available, the estimate may still update, but it should be interpreted more cautiously.
If you think the calculation missed something
- Identify the exact metric you expected SuperAge to use.
- Open Apple Health and confirm that metric exists there.
- Confirm the metric has recent entries.
- Open Data Sources & Access for that metric in Apple Health and check which app or device wrote it.
- Confirm SuperAge has permission to read that metric.
- Reopen SuperAge after the data appears in Apple Health.

What this does not mean
SuperAge is not a literal formula you can derive from one score input.
Do not treat the result as:
- proof that one specific metric caused the number
- a single-metric calculation
- a line-by-line formula you can reconstruct from one reading
- a full explanation without the surrounding context
The most useful way to read it is as a multi-signal estimate built from patterns, not as a one-input formula.
When to contact SuperAge
Email [email protected] if Apple Health contains recent data, SuperAge has permission to read it, and the app still appears to ignore it. Include the metric name, the date range, your device model, iOS version, and a short description of what looks wrong.
