How it works

Your Nervous System. Upgraded.

1. Put It On

SONA sits around your ear, & collects heart and respiration data, whilst stimulating the vagus nerve

2. Personalise Your Protocol

Pick the protocol that matches your goal, from rapid recovery to deep focus, or design your own

3. Connects to Your World

Pair SONA with soundscapes, music, respiration or beats to amplify effect.

4. Track, Learn, Refine

SONA learns how your nervous system responds and adapting stimulation to match

This is more than stress relief. It’s stress recovery. Designed to repair the circuits stress has rewired and help your brain return to balance.

Why Personalisation Matters

How much stimulation you need is determined by:

Your state of arousal. SONA reads your breathing rate and heart rate and identifies whether you are overactivated or underactivated. The more overactivated you are, the higher the dose.

The sensitivity of your vagus nerve. Different people need different doses. Over time the feedback loops within SONA enable it to learn what dose your specific VNS needs to see a response in key metrics like HRV.

And the effectiveness of that stimulation is determined by timing. Timing is Everything.

The vagus nerve is in constant flux, cycling between states of high and low excitability. SONA delivers pulses of stimulation exactly when your vagus nerve is most excitable. It’s like pushing a swing at the right time. The same effort carries it higher and smoother with every motion. Push at the wrong time, and the energy is lost or throws the rhythm off. By catching your body’s natural rhythm, SONA amplifies your relaxation response instead of fighting against it.

The result is a stimulation protocol tuned to your vagus nerve. And that means reaching a deeper state of calm for longer.
