Signal.OS

The Core Assessment.

See exactly which of your body's communication networks are carrying the most strain, and get your full personalized report.

$97USD, one time

Not a subscription. Not a membership. One purchase, one report.

The full Core Assessment — all 9 signal domains, the complete question set. Not the free preview map; the whole thing.
Your automated personalized report, generated from your own answers the moment you finish.
Your assessment history stays on your account — reopen your report, or retake the assessment later and compare.
Who it's for — people who want the full, structured picture of their own signal patterns, not just the free preview: anyone already following the doctrine and ready to go deeper, and anyone starting fresh who wants the complete assessment and report from day one.
See a sample firstSignal.OS example profile. This is an example. It is not your data.
Time required — plan for about 20–30 minutes to get through the full question set in one sitting. That's an estimate, not a guaranteed time.
Privacy — your answers and the report generated from them are stored on your account so you can reopen it later; they are not posted publicly. Signal.OS wellness data like this has its own consent and retention boundary, still being finalized — see privacy and data choices for what's confirmed live and what's still in progress.
Limitations — this is a wellness self-assessment for education, not a diagnosis, and never a "what to take". It reflects your own answers, not a lab test or a clinician's exam. Some patterns may be modifiable, but this report cannot establish a cause, prove an adaptation, or promise an outcome.

Already have a free account? The free Signal Integrity map is still there — this is the deeper, full assessment and report, sold on its own, not folded into membership. Educational, never a diagnosis.
