The Night Biofeedback Programme · Cohort 2 · a small group
JawSense ONE sits on your forehead while you sleep. Every time your jaw starts working, a small cue prompts it to let go. Most people don't notice it at all, and in the morning the whole night is in the app. We run the programme in small groups while we keep improving the training — join if you'd like to help shape it: try new technology, tell us what works, and see your own data every night.

I don't know if what I feel is a placebo effect, but it seems like my face is much more relaxed and I woke up this morning very relaxed, as if I were very clear-headed.

How it runs

Step 1
Two measured nights in your own bed — the before picture your twelve weeks are compared against.

Weeks 1–12
Not every night — aim for at least four a week; the rest are yours. Enough electrode patches for the whole twelve weeks arrive with the kit.

Every morning
Your jaw activity and your biofeedback data in the app, side by side: the cues delivered, and how well you responded to each one.

Three times
Three calls across the twelve weeks: we look at your nights together and pick better settings. Book extra calls whenever you want, and someone answers if anything breaks.
Patch on, sensor on, sleep. The only habit is charging it in the morning.
What you see
Every morning, last night's numbers are ready and waiting: episodes, bursts, duration and load, with every cue lined up against every jaw episode. Week by week you can see whether the biofeedback is doing anything — change a cue setting and watch what that does.
You keep both reports, written in plain English: your first two nights, and your twelve weeks. Same measurements, so you can put them side by side.



How you get in
The cues are set to your jaw, so we need to see it first.
2,600+ on the list
Before you apply
If your baseline comes back quiet
We say so before the cue weeks begin, and we talk it through with you: does carrying on still make sense?
If your skin won't take an adhesive for twelve weeks
Two nights of the Assessment answer that before you commit to twelve weeks.
If you are here for pain treatment
We are a wellness company, not a clinic. Jaw pain is a conversation with a clinician, and we will tell you that.
If you need the outcome guaranteed
We don't yet know whether the change lasts after the cues stop — that's still an open question in the research. The programme is built to find that out for you, not to promise you an outcome.
And if it does nothing for you, you will be the first to know.
Every night is measured, so a programme that changes nothing shows up as a flat line on your own chart.
Verbatim, from the exit calls
Ten people in our first cohort recorded a baseline night and a cued night we could compare directly. One night each, so we call it an early signal rather than proof.
How we measured it“It felt like someone lightly pulling the hairs above your forehead.”

“I was really surprised how easy it all was. It didn't bother me while sleeping.”

“I don't think there's anything on the market that addresses this problem… I'm not giving a 10 because the system has to prove itself over the longer term.”

Pricing

That's about €75 a week.
Twelve weeks of biofeedback tuned to your own jaw, in your own bed — every night measured on the same scale as your baseline.

What's included
The measurement
The retraining
The humans
The safety nets
The device is a loan, not a purchase. That's why twelve measured, coached weeks cost €897 instead of what it would cost to own a sensor you'd only need for three months.
The comparison
A night guard still protects your enamel, and plenty of people run both. The questions on the left are worth asking of any of them.
| A night guard | Trying things blind | The Night Biofeedback Programme | |
|---|---|---|---|
| Root causeIs anything about the habit itself changing? | No — it protects your teeth while the muscle carries on exactly as before. | Maybe. Nothing was measured, so nobody can say. | That's the entire job: biofeedback at the moment it happens, every night, for twelve weeks. |
| Accurate dataDo you find out whether it worked? | You find out how the guard is wearing. | You find out how you feel — impressions, not numbers. | Every night you wear it, on the same scale as your baseline. |
| What it asks of youWhat do you actually have to do? | Wear it, and remember to. | Keep trying things, and keep not knowing. | Go to bed wearing a patch. Twelve weeks of it. |
| Five years onWhat have you spent, and what do you know? | €800–2,400 in replacements, and as much about your jaw as on day one. | Whatever the last five things cost. Still no baseline. | €897, once, and a before-and-after you can still read. |
| If it doesn't workHow would you find out? | You wouldn't. Wear tells you about teeth, not about muscle. | You wouldn't. That is the trap. | Your own nightly numbers say so plainly. |
A sleep lab is still the most accurate way to measure this — but that means a night away from home, every night, usually with a waiting list. We measure the same muscle group, in your own bed. And a guard isn't competition: one protects your enamel, the other works on the habit. Guard prices are what a custom guard costs, replaced every one to three years.
You are in control
Comfortable is different for everybody, so you set these yourself.
01
How long the sensor waits after you go to bed before it cues you at all — so it leaves you alone while you're falling asleep.
02
How much jaw activity counts as an episode worth cueing. Higher catches more; lower catches only the heavy ones.
03
How strong the cue is, and there's a limit built into the device that it can never go past. Our first users describe it as a light flick on the forehead.
04
A ceiling, so a busy night cannot turn into a night of being nudged.
Some nights in the programme run with the cues off on purpose. That's how you — and we — see what your jaw does without them.

Cohort 1 was our first user test: seventeen people, two nights each, in their own beds. Each comparison is one cued night against that person's own baseline night.
