Know what people will remember and act on, second by second, right inside your app.
The Immersion SDK tells you what a person Values and whether they are Psychologically Safe, every second. When you know what someone Values, you can predict what they’ll do with over 85% accuracy. No camera, no microphone, no health data, and no added regulatory risk.
Any sensor in. Two numbers out.
Swift, Kotlin, or Python. One activate() call at launch, then pass samples with timestamps. Real-time or batch.

Sensor-agnostic: anything that gives your app accurate cardiac data works, including BLE heart-rate sensors, fitness devices, watches and wrist sensors, chest straps, sport shirts, smart glasses, finger pulse sensors, reflected RF, or a recorded heart-rate series.
import ImmersionKit
// Activate once at launch
let ok = try await Immersion.activate(company: "your_company_id",
key: "your_secret_key")
// Score a heart-rate sample
let point = ImmersionDataPoint(heartRate: 78, date: Date())
let score = try await Immersion.score(point: point)

Twenty years of published, peer-reviewed science. A decade of Immersion Neuroscience putting it to work for some of the most demanding companies in the world. The Immersion SDK puts that same measurement inside your app.

What the body can tell you, what HRV can't, and what the law now says about faces and voices.
Not what people say they feel. What their body reports.
- Value
- — 0–100, how important an experience is to the person. Predicts memory and behavior.
- Psychological Safety
- — 0–100, how comfortable the person is while it happened.
- Every second, instantly
- — a fresh pair of scores at 1 Hz from whatever sensor your app already reads. No round trip to a server.
- Runs entirely in the Immersion SDK
- — samples in memory, discarded after scoring. No cloud, no PII, no permissions of its own.
- Pro
- — local history, queries by minute, hour, or day, and key moments, all on the device.
The sensitive part never leaves your app.
No biometric identifier. No health data stored or transmitted. No named emotions inferred. No inference from a face, a voiceprint, or a brain scan. No permissions of its own.
