For the HRV-literate

The variable you haven’t isolated yet

Cold plunge, zone 2, no alcohol — and the trend line still won’t move. The missing input may be vagal tone. Ten minutes a day of low-frequency sound resonance on your sternum. Not electricity. Sound.

You’ve optimized everything except the brake

HRV is substantially a readout of vagal activity — the parasympathetic brake on your autonomic nervous system. Training load, sleep hygiene and alcohol all matter, but if vagal tone is the limiting variable, no amount of zone 2 will move it.

Most tools in this category try to activate the vagus nerve with electrical current. Sensate takes a different route: sound resonance, delivered acoustically through the sternum — bone conduction turning your ribcage into the transducer.

One input, ten minutes, daily. Then watch your own data.

Mechanism, not mystique

The device emits low-frequency sonic vibration against the sternum. Bone conduction carries that resonance through the chest, where the vagus nerve’s afferent pathways respond to the signal — helping tone the nerve and shift autonomic balance toward parasympathetic.

In a study, a single 10-minute session produced brain activity measurably similar to that of long-term meditators — the state experienced practitioners take years to train.

Sensate is the input, not the instrument. Pair it with your favourite wearable and treat it like any other protocol: baseline, intervene, measure the delta.

How Sensate works — sonic resonance felt through the chest

The numbers that matter

Study and pilot data — run your own n-of-1 on top.

1 session

to reach brain activity measurably similar to long-term meditators (study-backed)

48% decrease

in stress levels within 28 days of regular use (research study)

50% reduction

in time to fall asleep + 45–60 min more sleep per night (pilot study)

Ten minutes. That’s the whole practice.

Sensate isn't a tracker. It has no sensors and the app records nothing — bring your own device and judge us against your own baseline.

Baseline

Whatever you already wear — Oura, Whoop, Apple Watch, Garmin — is holding months of your data. That's your control.

Good questions

Is this vagus nerve stimulation?

No — and the distinction matters. Electrical stimulation devices drive the nerve with current. Sensate uses low-frequency sonic resonance through the sternum to help tone the vagus nerve — a gentle, non-invasive acoustic signal rather than electricity.

Will it move my HRV?

Individual results vary, which is why we publish study data rather than promises: 48% stress reduction over 28 days in a research study, and sleep gains in pilots. Sensate has no sensors, and the app doesn't record biometrics. It's the intervention, not the measurement. Keep using whatever you already trust, and hold Sensate to your own numbers. Run it against your own baseline — you have 90 days to test it, full refund if the data doesn’t convince you.

Do I need to pay for the app?

The core app is free and includes everything you need to use Sensate every day. Sensate Plus is an optional upgrade with a wider library of premium soundscapes.

How long until I notice a difference?

Most people feel noticeably calmer during their very first 10-minute session. In a research study, users saw a 48% decrease in stress levels within the first 28 days of regular use.

Is it safe?

Yes. Sensate uses gentle sound vibration — comparable to a cat’s purr resting on your chest. It is non-invasive and requires no effort from you. If you have a medical condition or implanted device, check with your doctor first.

What if it doesn’t work for me?

You have a full 90 days to try it. If Sensate isn’t for you, return it for a complete refund.

Run the experiment

90 days. Your wearable keeps score. Full refund if the data says otherwise.
