SomaCheck 1.0
Introducing SomaCheck: Vibecheck, the first release from Sensie, now on the App Store. Say a first-person statement, flick your wrist three times, about three seconds in all, and get an Aligned or Unaligned reading measured against your own baseline. No survey, no typing, no wearable.
SomaCheck is a body-based vibecheck for the moments when your state matters: before a meeting, a decision, a difficult conversation, or showing up for someone else. It is the individual product in the Sensie family, and everything in version 1.0 serves one promise: Notice sooner. Choose better.
A reading is a signal to consider, not a verdict. It tells you how your body responded to a statement, compared with your own baseline, in the moment before words had time to shape the answer. You decide what it means and what happens next.
The gesture
Every check follows the same five steps.
| Step | What you do | What happens |
|---|---|---|
| 1 | Choose the moment | Pick one of your check-ins, or write a statement of your own |
| 2 | Hold a first-person statement in mind | “I am ready for this conversation.” |
| 3 | Flick your wrist three times | Your phone's gyroscope and accelerometer capture about three seconds of movement |
| 4 | See the reading | Aligned or Unaligned, with the model's confidence [1] |
| 5 | Choose what is next | Agree, disagree, continue, or open optional guided support |
The movement is small. Think of flicking a water droplet off the top of your phone: three rhythmic, fluid flicks from the wrist, nice and easy. No camera is involved and nothing has to be worn. The phone already in your hand is the whole instrument.
The comparison is personal. SomaCheck does not judge your movement against anyone else's. During calibration it learns what your movement looks like when you hold something true, something false, something joyful, and something sad. Every reading after that is a comparison with you.
The result is honest about itself. A reading is always one of two words, and it always comes with the model's confidence. When a capture is too still or too rushed to read, SomaCheck asks for another gesture rather than guessing.
Hearing your signal
While you move, SomaCheck plays continuous sound that changes with the motion. It is not decoration. It is the same signal the reading is built from, played back to you as it happens.
| What the motion does | What you hear |
|---|---|
| Swirls more or less (vorticity) | Pure tone, or richer overtones |
| Keeps a steady spin (spin coherence) | Perfect intervals, or beating between notes |
| Wobbles at the wrist (precession) | Smooth sustain, or grain and shimmer |
| Carries its energy low or high (energy cascade) | A warm low register, or a thin high one |
| Flips direction (helicity sign changes) | An even line, or small rhythmic stutters |
A coherent movement sounds consonant and rich. A disrupted one adds texture. You hear alignment and misalignment while the gesture is still happening, before your mind has time to build a story about it. Then the reading arrives.
Two things are worth saying plainly. The sound is feedback; the reading is the result. [2] And headphones make it better. SomaCheck asks you to check your sound before your first calibration for that reason.
Calibration is a game
Before SomaCheck can read you, it has to learn you. We built that part to be played, not endured.
- Learn the gesture. A short tutorial shows the flick. You try it until it feels loose.
- Strike the gong. Flick your wrist to strike a gong, three times, across three rounds. This is where you find your rhythm and SomaCheck finds your range.
- Joy and sadness. Two rounds each. Bring to mind something that genuinely makes you happy, let the feeling express itself in the gesture, then do the same with something that makes you sad. Joy and sadness teach it how your body speaks.
- The congruence game. SomaCheck shows you something, a car, a flower. You hold in mind either what you see or something different, and flick. It guesses which. You tell it whether it was right.
- True and false. Statements about yourself that are true, then statements that are false. Hold each one in mind and flick three times.
Then it starts reading you. The app says it straight: early reads may miss, and every answer teaches it. There is a milestone screen for the moment your personal model becomes officially better than a coin flip, and still learning. We think that honesty is part of the product.
One practical note from testing: a bulky case or a PopSocket can muffle the read. Pop it off if you can.
A check-in that is yours
SomaCheck tunes your check-ins to what you choose. During setup you pick up to three challenges you are working with and tell it a little about what you do. Those choices seed your first check-ins, and you can change them in Settings any time.
Two moments are built in. Walk in ready: a check before the meeting, the decision, the conversation. Find your center: one quiet minute to check in, notice what comes up, and choose how to move forward.
Journey keeps your completed check-ins together. Revisit a statement and notice what repeats. There is no social feed and no public score.
When a reading comes back Unaligned, you can open techniques to explore the signal, find your center, and move forward. That includes Satyen AI, a 30-minute AI-guided selfcare session built with Satyen Raja, our Chief Cultural Officer. It is an AI guide, not a live appointment and not therapy.
Your feedback sharpens the model without rewriting the past. When you agree or disagree with a reading, that answer is stored separately from the reading itself. The original prediction is never overwritten. [3]
Privacy and honesty
What a reading is
A reading is about you in relation to one statement, measured against your own baseline. It is not a fact about the world, and it is not an instruction. Two people can hold the same statement and get different readings, and both readings can be right about their owners.
What leaves your phone
There is no camera and no wearable. There is no social feed and no public score. You control any connected context sources and any links to other tools from Settings, and you can remove them at any time.
What we do not claim
SomaCheck is a wellbeing tool. It is not a medical device and it does not diagnose or treat any condition. Early reads can miss, which is why every reading carries a confidence and why the app asks for another gesture when a capture cannot be read. Our research line is exactly this: researched with PhDs from Oxford, UC Berkeley, and Northwestern; research trials in preparation at Columbia University and Mayo Clinic. [4]
What is coming
One more thing is already in the app, and we are not going to explain it yet. If you have an AI assistant you talk to every day, take a look in Settings. The next post is about that.

Notice sooner. Choose better.
Footnotes
- A valid reading is always Aligned or Unaligned. A low-confidence reading is still one of the two; confidence describes the classifier's uncertainty, not a third answer. A capture that cannot be read technically asks for a retry and produces no reading. ↩
- The sound engine maps live motion features (vorticity, spin coherence, precession, energy cascade ratio, helicity sign changes) to harmonic richness, consonance, texture, register, and rhythm in real time. The reading is produced by the classifier, not by the sound. ↩
- The original proposition, prediction, and confidence are stored separately from any feedback you give after seeing the result. Feedback contributes to learning through a separate, deliberate process; it does not retrain the model on the spot. ↩
- “In preparation” means the studies are designed and not yet enrolling. SomaCheck makes no claims about diagnosis, treatment, or improved outcomes. ↩
