EMDR Trace

EMDR Trace is an iOS app designed to support EMDR professionals with flexible bilateral stimulation, optional eye tracking, and real-time observation during guided sessions.

The app combines visual, auditory, and haptic bilateral stimulation, which can be used independently or synchronized. Professionals can adjust stimulus speed, movement range, and duration to suit each session.

Key features include:

• Eye Tracking: Uses compatible Apple devices with TrueDepth cameras to observe how a participant's eyes follow the moving stimulus.
• Session Insights: Displays descriptive metrics for Follow, Timing, and Movement Range, compared against an individual session baseline.
• Adaptive Stimulation: Automatically adjusts visual stimulus pacing based on observed eye movement patterns, while keeping the professional in control.
• Flexible Device Setup: Run sessions on a single iPhone or iPad, or use separate devices for the professional and participant.
• Remote Sessions: Connect professionals and participants in different locations through FaceTime and SharePlay, with synchronized bilateral stimulation and remote session control.
• Multimodal Stimulation: Combine visual movement, alternating stereo audio, and bilateral haptics through compatible controllers.
• Practice & Simulation: Explore session workflows and different eye-following patterns without requiring a participant.
• Privacy by Design: Eye tracking is processed locally on the participant's device, without transmitting camera images to external servers.

EMDR Trace also supports Apple Watch controls and compatible Apple silicon Macs.

The app offers free basic functionality, with advanced features available through an optional Pro subscription.

EMDR Trace is a tool for bilateral stimulation and observation. It does not provide diagnoses, clinical recommendations, or treatment outcome assessments.
