Headphones recommended
From video game controller to a possible clinical tool.
This demo runs solo. The real app syncs your view to a client device — and saves everything that matters.
Designed for the session, not against it.
No installs. No accounts for your client. Three steps from opening your laptop to pacing your first set.
Create
One click generates a session and a secure client link. No setup, no waiting room, no account required from your client.
Share
Paste the link into SimplePractice, Zoom, or your platform's chat. Your client opens it in their browser — that's it.
Conduct
Drive speed, color, and pacing from your panel. The client sees a clean, distraction-free display — perfectly synced.
Every detail, clinically considered.
The tools you'd build for yourself if you had the time — already built, tested, and quietly handling the work.
Controller-based haptics
Pair a PS5 DualSense or Xbox Wireless Controller. Rumble follows the ball — left grip when left, right grip when right. From video game controller to a possible clinical tool. No buzzers to ship, no hardware to set up.
Stereo bilateral audio
A tone pans left ↔ right in real time, frame-for-frame with the ball. Headphones required for the effect — and the moment a client hears it, the rationale for bilateral stimulation lands without explanation.
Therapeutic Soundboard
Binaural, isochronic, pure-tone, and pink/white noise tracks — each one labeled with study status and the evidence behind it. Honest about what the research says, even when it’s thin.
Perfectly in sync with your client
What you see is what your client sees — frame for frame. No lag, no skipped beats, no “are you seeing the same thing?” mid-session.
Fully customizable pacing
Speed, ball size, color, background — preset or fine-tune. From a fast pulse to a slow, calibrated pace, adjusted live without breaking the session.
Therapist + Client modes
Your panel stays private. Your client sees only what they need to see — distraction-free and read-only.
Built-in session timing
Stopwatch, countdown with end-of-time alert, and per-set phase timing — no second screen, no second app.
Pre & post check-ins
Capture client state before and after — and longitudinally weeks or months later — to track lasting change.
Accessibility built in
Built to recognized accessibility standards, with a high-contrast theme designed for low-vision clinicians and clients.
Already use bilateralstimulation.io? Here's what changes.
Real questions from the ART Therapists Working Together Facebook group, 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 — 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.
ART support
Built for both EMDR® and ART® — not just EMDR.
bilateralstimulation.io · Built and marketed around EMDR; ART therapists adapt an EMDR-shaped workflow to their protocol.
Psy180 · ART-first as well as EMDR. Self-attested ART certification at signup, trademark-correct ART® language throughout, and a session structure — pacing, phases, and a viewer for your own protocol scripts — shaped to fit how ART sessions run. You bring the clinical protocol; Psy180 is the tool around it.
Tactile hardware
Use the controller your client already owns.
bilateralstimulation.io · Proprietary $129 wired buzzers, ordered and shipped to each client.
Psy180 · Live today: pair a PS5 DualSense or Xbox Wireless Controller — the left and right grips pulse with the ball as bilateral haptics, side for side. No proprietary hardware to buy or ship.
Shipping quietly, often.
Psy180 is built one well-tested feature at a time. Here's what's next.
Revisit any past session. Compare a client's emotional vocabulary one week, one month, or one year out.
Per-set timing across every play / pause / reset cycle, captured automatically for documentation.
iOS & Android. Use Psy180 anywhere you practice — your phone becomes a fully synced client display.
For clients who have a hard time paying attention to the bilateral stimulus — done in a way that's still clinically sound, not by working around the modality.
Your voice shapes what ships next.
Psy180 is built by one person — Jake — listening to one group of people: clinicians who actually run sessions. When you become a paid member, you get a direct line to the inbox. Your idea gets read. If it's something Jake can build, he'll build it and write you back when it ships. If he can't, he'll tell you why. That part isn't marketing — it's the rhythm this product is built on.
You write
About what your practice actually needs.
The phase you wish Psy180 had. The friction you hit in last Tuesday's session. A product idea for therapists that has nothing to do with Psy180 yet. Send all of it.
Jake reads
Every message. Personally.
No tickets, no triage queue, no AI summary. The volume is paid- member only so this stays humanly answerable — which is the whole point.
And then ships
What you asked for, with your name on it.
When the thing you suggested ships, you hear from Jake — not a changelog, a real note. That email is one of the reasons paid members stay.
Free forever for BLS. Paid for the clinical workflow.
