Vagal Buddy vs Nemos
Nemos pioneered non-invasive vagus nerve stimulation. Vagal Buddy was built on the same principles. Here is what they share — and where they differ.
Vagal Buddy
$349
Nemos
~€3,500
Stimulation type
Current-controlled tVNS
EverSteady adjusts in real time, keeping the current constant regardless of changing skin impedance. The dose you set is the dose delivered.
Stimulation type
Current-controlled tVNS
Nemos also delivers current-controlled stimulation, maintaining a consistent dose independent of skin conditions. The clinical gold standard.
Electrode material
Titanium
Biocompatible titanium electrodes — the same material used in medical implants. Gentle on skin, even with daily use.
Electrode material
Titanium-iridium
Medical-grade titanium-iridium electrodes, also chosen for their biocompatibility and low irritation profile.
Stimulation protocols
Doctor-created, app-updatable
Clinicians can create custom protocols. New protocols are delivered through the Vagal Tones app as research advances — no hardware swap needed.
Stimulation protocols
Doctor-created, app-managed
Clinicians programme stimulation parameters remotely. The tVNS Patient App manages sessions and protocol delivery.
Session logging
Current delivered, logged per session
The Vagal Tones app records actual current delivered during each session, giving users and clinicians a clear treatment record.
Session logging
Current delivered, logged per session
The tVNS Patient App tracks session duration and stimulation data, providing a diary of treatment history.

Clinical-grade tVNS needn't cost €3,500.
Nemos invented this category. Current-controlled stimulation, titanium electrodes, doctor-created protocols, session logging — they set the standard. Vagal Buddy was built on those same principles with EverCharge wireless charging. The difference is the price, and who can buy one.
