Now testing · Cervical dystonia with DBS · AirPods Pro required

Your AirPods are already
a movement monitor.

Your movement, measured.

Vexa uses the motion sensors already in your AirPods Pro to record how your head moves through a real day — then turns weeks of sessions into a report your neurologist can read before adjusting your settings.

"My neurologist sees me for 20 minutes every few months and adjusts my DBS settings based on what they observe in the room. But my tremor varies enormously throughout the day. There was no way to show them what my life actually looks like."

— Built by a patient, for patients

The problem

Programming shouldn't be
guesswork.

Clinic visits are snapshots. Between them there is no objective record of how a DBS program actually performed across a real week — at home, at work, when tired, when stressed.

Vexa records that week, and keeps it with the settings you were on.

How it works

Four steps.
Weeks of data.

1
Log your settings
After a programming appointment, enter your programs and levels once. Medtronic, Abbott and Boston Scientific terminology are all supported. Every session from then on is tagged with what you were running.
2
Record sessions
Put your AirPods Pro in and start a session — a free session while you get on with your day, or a two-minute guided benchmark you repeat the same way each time. Phone in your pocket, screen off.
3
Rate it, then see it
At the end we ask how it felt before showing you any numbers. That's deliberate: your own rating is part of the record, not an echo of the app's.
4
Bring the report
Before your next appointment, generate a PDF: your programs side by side, your sessions grouped by appointment, your notes. Share it from your phone.
Straight answer

What works today,
and what's still experimental.

Vexa is being tested by people with cervical dystonia and DBS right now. The workflow is solid. The measurement is real but has not yet been validated against clinical scales — so we label it that way, in the app and here.

Works todayThe workflow
  • Programming log. Programs, left/right levels and appointment dates. Sessions are grouped by appointment automatically.
  • Free sessions and benchmarks. Record in the background with the screen locked. If your AirPods disconnect or you walk away from the phone, what was recorded is saved — nothing is lost.
  • Your own ratings. Typical and worst severity after each session, asked before the numbers are shown.
  • Voice notes. Say what's happening; the transcript is kept with the session and tagged (the transcript alone is sent to an AI service for the tag — nothing else leaves your phone).
  • Program comparison. A by-program view so you can see which settings your sessions were recorded on and what they showed.
  • PDF report and data export. A multi-page report for your clinician, and a full export of your own data at any time.
Everything is stored on your phone. There is no account and no Vexa server holding your sessions.
ExperimentalThe measurement
  • Severity score (0–10). Computed from head motion in the dystonic tremor band. It is consistent from session to session, but it has not been validated against TWSTRS or any clinical scale, and it can under-read sustained pulling.
  • Movement-quality metrics. Shown under an "Experimental" label as multiples of a control range — not as a score, not as better or worse.
  • Heart-rate context. If a wearable writes heart rate to Apple Health, Vexa shows it alongside your sessions. Context only; it never changes a score.
Vexa is a monitoring tool, not a diagnostic device. Nothing it shows is medical advice, and nothing it shows should change your treatment without your neurologist.
Conditions

One condition, done properly.
Then the next.

We ship a condition when the whole thing works — recording, trends and the report — not when the copy is ready. That's why the list below is short and honest.

Your programs, side by side.
Generated on your phone.

Every program you ran, the levels you were on, and what your sessions showed — laid out by appointment so your neurologist can see what changed and when. Page one is the summary; the following pages carry the evidence, your notes, and a plain statement of what the numbers can and can't tell you.

What you need

Nothing to buy —
but two things to check.

AirPods Pro
AirPods Pro, any generation. These carry the motion sensors Vexa reads. Regular AirPods don't. AirPods Max also have the sensor but are unmeasured so far — tell us if that's what you have.
iPhone
iOS 18 or later. Vexa is an iPhone app and runs through Apple's TestFlight during testing. There is no Android version.

Why we built this

The data your neurologist
has never been able to see.

Vexa was created by someone living with cervical dystonia and bilateral GPi DBS. After five programming visits in seven months — with the neurologist adjusting settings based on 20-minute observations — it became clear that something was missing.

The neurologist needs to know what the weeks between visits actually look like. Which program worked best on a Tuesday afternoon. Whether the change made last month held up at work, or only in the clinic.

That record doesn't exist yet. Vexa creates it — and the people testing it now are shaping what it becomes.

Two ways in

Test it now, or
hear when it launches.

Testing is open to a small group of people with cervical dystonia and DBS who have an iPhone and AirPods Pro. Everyone else — and anyone who'd rather wait for the finished app — can join the launch list. Founding members get early access and founding-member pricing.
