Where HALO fits

How HALO Compares

HALO defines a new category — non-invasive, multimodal cognitive-state awareness. See how it stands against adjacent technologies.

HALO compared against adjacent neurotechnology categories

Invasive surgical brain implant (BCI)

HALO vs. Neuralink

Neuralink implants a surgical electrode array to deliver high-bandwidth neural control. HALO takes the opposite path: a non-invasive forehead BCI that reads cognitive state — focus, load, stress, recovery — and surfaces it as the Harmonic Index. One pursues control through surgery; the other pursues cognitive-state awareness you can wear in seconds.

Neural implants (e.g. surgical electrode arrays)

HALO vs. invasive brain-computer interfaces

Implanted BCIs deliver extraordinary signal fidelity but require neurosurgery, carry clinical risk, and target medical restoration. HALO trades single-neuron resolution for a non-invasive, wearable, everyday platform that anyone can put on in seconds.

Single-purpose meditation EEG wearables

HALO vs. consumer EEG headbands

First-generation EEG headbands proved people will wear brain sensors. But most capture EEG alone, focus narrowly on meditation, and stop at raw band-power feedback. HALO fuses EEG with PPG, EDA, IMU, and temperature into a calibrated cognitive-state model.

Wrist-based health & stress tracking

HALO vs. smartwatch wellness tracking

Smartwatches infer stress and readiness from heart rate and HRV at the wrist. They are excellent at the body — but they never see the brain. HALO measures neural activity directly at the forehead, then fuses it with the same physiological signals.

Software-only attention & mindfulness tools

HALO vs. focus & meditation apps

Focus and meditation apps guide behavior but fly blind — they have no measurement of your actual cognitive state. HALO closes the loop: it senses your brain and body, then adapts guidance to what is genuinely happening inside you.
