Somatic is a consumer iOS app for nervous-system regulation. Not somatic therapy. Not a wearable. Not another meditation library.

See what actually settles your body.

Somatic measures your heart rhythm before and after short evidence-anchored practices, then shows you — with your own data — which ones move the needle. No verdicts. No vibes.

90 seconds, seated, still. No hardware. iPhone only for now.

The problem

You've tried five apps. You still feel wired most weeks.

You already know the drill. A meditation app sits half-finished on your phone. Your watch tells you your HRV every morning and you have no idea what to do with the number. You've done breathwork on TikTok, bought the hardware clip that's now in a drawer, paid for a subscription you forgot to cancel.

A year later, you still snap at people you love. You still can't wind down at night. And you still can't tell what — if anything — was actually working.

Either it's not landing for your body, or none of it actually works — and you have no way to tell which.

The thing none of those apps gave you was the one thing that would have settled it: a measurement loop honest enough to prove what's helping your body and what isn't.

How the loop works

Three steps. Five minutes. Your own data.

Step 01 — Measure

A 90-second standardized scan.

Same posture, same time of day, every morning. Your phone camera reads your pulse and computes RMSSD — the time-domain HRV metric that holds up against ECG at rest. You see today's reading against your personal rolling baseline. Not "you're stressed." Just "38 ms — inside your normal range of 32–46. Readiness: moderate."

Metric: RMSSD · Method: photoplethysmography (camera) · Wearable: optional

Step 02 — Match

One practice, picked for you, today.

Somatic looks at your goal, the time of day, where today's reading sits in your range, and your recent check-ins, then recommends a single 3–5 minute protocol — slow-paced breathing, HRV biofeedback, an extended-exhale pattern, a grounding sequence, or a gentle somatic movement. One practice. Not a catalog to scroll.

Step 03 — Prove

A 20-second scan before. A 20-second scan after.

You see the actual delta in your physiology. "RMSSD up 12%. Your nervous system responded to this one." Some weeks the practice lands. Some weeks it doesn't. You stop guessing.

And every 7–14 days, Somatic re-administers PSS-10 and GAD-7 — the validated stress and anxiety questionnaires clinicians have used for decades. You watch the score line move. Or not. That's the proof.

What makes Somatic different

Three things you won't get from a meditation app, a wearable, or a hardware sensor.

01

Trend, not verdict

Your HRV doesn't get a thumbs up or thumbs down. Every reading is shown against your own rolling 7-, 14-, and 30-day baseline, with a confidence band. Your number is yours. We compare you to you.

02

Pre/post on every session

Twenty seconds before, twenty seconds after. You see the practice's effect on your physiology in real time, the same morning you did it. The work either moves your body or it doesn't, and you find out today — not in six months.

03

Validated outcome proof

PSS-10 and GAD-7 aren't our scores. They're the validated self-report instruments used in stress and anxiety research. We re-administer them every 7–14 days and show you the line. Your stress score is moving, or it isn't. No internal app score we made up.

"But wait —"

The questions you're already asking.

At the margins, that's true. Smartphone camera PPG runs about 11–17% MAPE against ECG for RMSSD at rest, with correlations above 0.9. That's accurate enough for tracking your own trend, which is how we use it. We don't use it for frequency-domain metrics where it isn't reliable, and a quality gate runs on every scan — if the signal isn't clean, we don't show you a number. We ask you to redo it.
Your wearable shows you a number. Somatic shows you what to do about it. We match a short evidence-anchored practice to where you are this morning, measure the effect before and after, and re-administer PSS-10/GAD-7 every couple of weeks so you can see whether your stress score is actually moving. Wearable equals reading. Somatic equals reading plus practice plus proof. (Apple HealthKit read is on the roadmap so your wearable's HRV feeds in.)
Slow-paced breathing is one tool in the library. The product is the loop — baseline → match → pre/post delta → weekly outcome score. Breathwork apps don't measure outcomes. We do.

Start with your baseline.

Three scans across onboarding to establish your personal range. A short PSS-10 and GAD-7 to anchor where you are today. Then your first matched practice — and the first pre/post delta in your own data.

Five minutes. Free to start. iPhone only for now.
