How you look is how you're aging.

Know which treatment actually worked.

Understory reads your labs, skin, wearables and treatments together — and finds the one number quietly holding your results back.

One move, not a data dump

Understory ranks everything you generate and hands Farrah the single highest-leverage action this month — raise iron. No dashboards to decode; just what matters, and why.

The proof · Farrah, 41
$6,000 in treatments, held back by one blood number.

Farrah invested in the right treatments — her skin score climbed from 64 to 73 — then stalled. Here's what Understory's longitudinal, cross-domain view caught that no lab, scan, or skin app alone could.

The connection no single test could make

Iron is a required cofactor for collagen cross-linking. Below the performance band, Farrah's microneedling, PRF and filler all under-delivered — her score climbed, then flattened. Understory caught it by connecting her labs → treatments → skin over time. Fix a ~$15/mo iron protocol first, and the treatments she's already paid for finally pay off.

Six treatments. One number holding them back. That's the difference between spending and results.
And it isn't just your skin.

Lean-muscle percentile vs. women 40–49
The muscle you're leaving on the table

Farrah's lean mass sits at the 11th percentile — the single biggest untapped longevity gain she has. Low free-testosterone and light protein blunt the response. 90 days of resistance training and protein projects the 45th. Same engine, different domain.

A daily insight, and a monthly deep-read.
Two rhythms keep you close to your body — a fast read every morning, a full synthesis every month — with one deterministic, evidence-graded engine underneath both.

The Daily Dashboard

Every morning, in 30 seconds: your readiness, what changed overnight, and the single move that matters today — connected to your skin, labs and treatments.

The Understory

Your monthly report. The full cross-domain synthesis — what's working, the one biology holding your results back, the contraindications between your treatments and meds, and exactly what to take to your provider. Educational, never a diagnosis.

The Nexus

The engine beneath both: low iron isn't just fatigue — it blunts your collagen, recovery and sleep. One root cause, surfaced across your whole body.

How it works.
Bring what you already have. Understory does the synthesis.

The engine connects it

A deterministic, evidence-graded engine finds the cross-domain threads and ranks your single biggest lever — every insight carries its confidence grade and sources.

Act with confidence

The Daily Dashboard gives you the morning read; The Understory — your monthly report — goes deep on what's working, what to change, and what to raise with your provider.
