Two paths

Built for the person holding the Joy-Cons — and the clinician across the room.

Self-administered grounding for everyday anxiety, or a discreet administration tool during an in-session EMDR protocol.

For yourself

A pocket
ritual for
regulation.

Pair your Joy-Cons, pick a preset, and let slow alternating taps bring you back into your body. Ideal for winding down, re-centering after a meeting, or evening grounding.

  • Four curated presets + fully custom
  • Gentle session summary, private journal
  • No streaks, no nagging, no data collection
Start using it
For clinicians

A quiet tool
during the
session.

Hand both Joy-Cons to your client for silent tactile BLS. You control speed, intensity, and duration from the phone — no client data is stored on the device.

  • Save your recipes, reuse instantly
  • Large, discreet controls — phone can sit on the couch
  • Zero PHI — your EHR stays the source of truth
For my practice
How it works

Three small steps
to a quieter nervous system.

01

Pair both Joy-Cons

Tap the little sync button on each controller. TheraJoy finds them in seconds and shows battery, handedness, and haptic health.

02

Choose a preset — or tune your own

Calm, Standard, Process, or Custom. Dial speed, haptic intensity, passes per set, and duration to match how you feel today.

03

Hold, breathe, and follow

Left-tap, right-tap. A slow pendulum on screen mirrors the haptic rhythm in your hands. Close your eyes if you want. The app tracks passes and time for you.

"Bilateral stimulation already lived in my therapy room. TheraJoy turned it into something my clients could keep in their hands. The design gets out of the way."

Thoughtful details

Built slowly,
for the still moments.

Every control sits where your thumb already is. Every screen is calm by default, with a deeper set of tools the moment you need them.

Calibrated tactile rumble

Each pebble's haptic engine is tuned for slow bilateral rhythm — a soft, grounded pulse in the palm, not a buzz. The heart of the session is what you feel, not what you see.

Three BLS visuals

Orb, Horizon, or Ambient — switch mid-session with a tap, or close your eyes entirely.

Fully custom presets

Save the recipe that works — speed, haptic strength, passes, duration — and pull it up in two taps.

Session journal

Optional, private, unprompted. A one-line note stays on your device.

Quiet by design

No accounts, no analytics, no push notifications. The app opens, works, and closes.

What's bilateral stimulation?

Left, right, left. A pattern
your body already trusts.

left right

Rhythmic, side-alternating input — a metronome in each hand — is a core element of EMDR and several sensorimotor approaches. It can help anchor attention in the body and down-regulate a busy nervous system.

i
Tactile over visual

Haptics let you close your eyes. We default to tactile; visual and audio are optional layers.

ii
Tempo that fits the moment

Slower for grounding. Faster for processing. Both supported, with gentle defaults.

iii
Not a medical device

TheraJoy is a wellness tool. It is not a replacement for EMDR therapy, diagnosis, or treatment.

Hardware

Works with what
you already own.

Joy-Cons lead the way, but TheraJoy can drive whatever gives you a good left-right pulse.

Recommended

TheraJoy Pebble — pair of matte black haptic stones
The Pebble by TheraJoy

A palm-sized pair,
built for one job.

When your eyes are closed and your breath is slow, a game controller is the wrong object in your hands. Pebble is our own take: a matched pair of matte-soft, palm-rounded shells, each with a single linear motor, designed to disappear into the act of grounding itself.
