A clean, quiet source of bilateral stimulation — alternating left-right visual motion and sound. Pay once. No account, no subscription, and no data collected. Ever.
Bilateral stimulation (BLS) is the alternating left-right stimulus used in EMDR (Eye Movement Desensitization and Reprocessing) practice, and many people also use it simply to settle, refocus, or wind down. Simple EMDR does one thing well: it gives you a precise, configurable BLS source with nothing else in the way.
VISUAL STIMULATION
- A smooth-moving ball — or any emoji you choose — in the size and color you want
- Three paths: Sweep with adjustable arch, Figure-8 with lobe height and twist, S-Curve with adjustable wave depth
- Horizontal or vertical motion, 10–120 cycles per minute
- Black, dark gray, or custom background
AUDIO STIMULATION
- Alternating tones, hard-panned left and right (headphones recommended)
- Sine, triangle, or click — with adjustable pitch, tone length, and volume
- Runs on its own for eyes-closed sessions, or in sync with the visual marker
SESSIONS, YOUR WAY
- Continuous mode with an optional timer
- Set-based mode: choose passes per set, rest length, and number of sets
- Tap to pause. The screen stays awake. Nothing interrupts.
PRIVATE BY DESIGN
- 100% offline — the app has no network access at all
- No account, no analytics, no third-party code
- Privacy label: Data Not Collected
- One-time purchase. No subscription, no ads, no upsells.
Designed for iPhone and iPad — iPad's larger screen gives an especially wide visual sweep. Clinicians: Simple EMDR also works well as a client-side stimulus during remote sessions, fully controlled on the client's own device.
IMPORTANT
Simple EMDR is a wellness tool that provides bilateral stimulation for relaxation and focus. It is not a medical device, does not provide therapy or treatment, and is not a substitute for care from a qualified professional. If you are working through trauma, use it only under the guidance of a licensed clinician. Stop if you feel unwell.
