Your body knows before you do.
Soulace reads your heart rate and skin conductance in real time, and uses an onboard AI model to catch the physical onset of anxiety, the racing pulse, the first sweat response, before it builds. The moment it detects that shift, the band delivers a low-frequency infrasonic vibration to your wrist to help calm your nervous system back down.

Real-time response
Reads you. Answers you.
Most wearables stop at a chart. Soulace senses the spike and answers it in the moment, a gentle pulse at the wrist that helps steer your nervous system back down, hands-free.
Not a buzz. A settle.
A calm you can feel.
Not a beep, not a notification. A low, felt infrasonic pulse designed to meet your body's stress response where it starts and help bring it back toward balance.
Most anxiety support arrives after the moment has already passed.
Breathing apps, journals, and check-ins all ask you to notice you're anxious first, often minutes after your body already has. Soulace's sensors watch the physical signals directly, so it can respond at the moment of onset, not after the thought spiral has taken hold.
2 sensors
Heart rate (PPG) and skin conductance (EDA), read continuously from the wrist.
On-device AI
A personalised model learns your baseline and flags meaningful shifts, not generic thresholds.
Infrasonic
A felt, low-frequency pulse, not a sound, not a buzz, delivered right at the wrist.
Private
Sensor and symptom data stays yours: exportable, deletable, never sold.
Four steps, running quietly on your wrist.
Soulace doesn't ask you to manage anything mid-episode. It senses, decides, and responds automatically, you only reflect once things have settled.
01
Sense
Optical and electrodermal sensors track heart rate and skin conductance continuously from the wrist.
02
Detect
An onboard AI model compares live readings to your personal baseline to catch early signs of anxiety onset.
03
Respond
The band delivers a low, steady infrasonic pulse designed to help calm the nervous system and support autonomic balance.
04
Learn
A short, optional check-in afterwards refines what anxious looks like for you, so detection sharpens over time.
Built for the moments your body reacts first.
Work pressure
A presentation, a deadline, a hard conversation. Soulace catches the climb in heart rate and skin conductance before it crests, and answers it in the moment.
Social settings
Crowds, calls, the build-up before you walk in. The band meets the onset where it starts, so you can stay present instead of bracing.
Restless nights
Pulse still up when the lights go out. The infrasonic pulse cues the wind-down your body doesn't always find on its own.
Two signals, read together.
Heart rate alone rises for lots of reasons, exercise, caffeine, standing up. Skin conductance (electrodermal activity) responds specifically to sympathetic nervous system arousal, the same system involved in anxiety. Reading both together, against your own baseline, gives a more reliable signal than either alone.
Onset window: both signals rise together, then settle after response
PPG heart-rate sensor
An optical sensor at the wrist tracks beat-to-beat heart rate continuously.
EDA skin-conductance sensor
Two small electrodes measure the skin's electrical conductance, which shifts with sweat gland activity tied to sympathetic arousal.
Infrasonic vibration response
Low-frequency vibration, below typical hearing range, delivered as a felt pulse designed to help calm the nervous system and support autonomic balance.
Every reading, made visible.
The app shows the same heart rate and skin conductance data the band is already reading, alongside every onset it caught and how you responded, so you can see, over weeks, whether things are actually easing.
- Live sensor view Real-time heart rate and skin conductance readings, not just a daily summary.
- Onset detection log Every moment the band responded, timestamped, with your own note on whether it helped.
- Trend view Weekly and monthly views of frequency and intensity, so progress is visible, not just felt.
- Share with your therapist Export a clean summary of sensor trends to bring to a session, if and when you choose to.

Before you wear one.
No. Soulace is a wellness product designed to support relaxation and stress resilience through sensing, vibration, and personalised tracking. It is not approved to diagnose, treat, prevent, or cure anxiety or any other condition, and it isn't a replacement for therapy, medication, or professional care. If anxiety is affecting your daily life, please speak with a doctor or licensed therapist.
