Free haptics and binaural audio, right in the browser.
This demo runs solo. The real app syncs your view to a client device — and saves everything that matters.
Every detail, clinically considered.
The tools you'd build for yourself if you had the time — already built, tested, and quietly handling the work.
Already use bilateralstimulation.io? Here's what changes.
Real questions from working clinicians, answered with the differences that actually matter to your practice.
Free tier
A free tier that grows into your practice.
bilateralstimulation.io · A genuinely free plan — visual, auditory, and basic tactile BLS, unlimited, no signup. But it's anonymous: with no account, nothing carries from one session to the next.
Psy180 · A permanent free tier with email-only signup. The same bilateral stimulation engine the paid plans run on — visual, stereo audio, and controller haptics, all unlimited — and the account is what lets your work persist and grow into the clinical workflow when you're ready. No card, no expiration.
Clinical workflow
More than the animation — a clinical record that lives between sessions.
bilateralstimulation.io · Saves a client's BLS preferences on the paid plan — but not a clinical record: no session history, no pre/post check-ins, no outcome tracking over time.
Psy180 · A clinical record that travels with each client: saved profiles and BLS preferences, session history with your notes, pre- and post-session emotion and distress check-ins, longitudinal tracking across weeks or months, and an in-session PDF script viewer.
Modality neutrality
Modality-neutral by design — no one therapy's workflow baked in.
bilateralstimulation.io · Built and marketed around EMDR; clinicians in other BLS-based modalities adapt an EMDR-shaped workflow to their own.
Psy180 · Built without assuming one modality's workflow: a continuous 0.5–2.5 Hz pacing range instead of presets tuned to a single approach, and a viewer for whatever protocol documents you bring. You bring the clinical protocol; Psy180 is the tool around it.
In-app video
Video and BLS in one tab — not Zoom in another window.
bilateralstimulation.io · A standalone BLS animation. To see your client’s face, you run it alongside a separate video platform — Zoom, Doxy, SimplePractice — in another tab, juggling the two the whole session.
Psy180 · 1:1 video built into the session itself. The client’s face sits in a tile you can drag and resize — small while the ball moves, full-size when you talk — over the same BLS the paid plans run. Peer-to-peer, encrypted in transit, and never recorded. (Solo and up; free-tier therapists can still share their own telehealth link.)
