About

Simple EMDR

Features
Read full description

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.
