Frequently asked questions
Is the EMDR light bar really free?
Yes. It runs in your browser with no account, no email and no ads. The EMDR Flow app adds therapist-controlled remote sessions and the Coach with AI virtual patients.
What speed should I use?
Speed is a clinical decision. The tool starts at 1 full left-right-left pass per second and lets you go from 0.4 to 1.6. Your EMDR therapist sets the speed and length of each set.
Can I use it in an online EMDR session?
Yes, with remote sessions: the therapist runs the session from the EMDR Flow app and the client joins from any browser at emdrflow.app with a code, without installing anything. The therapist controls speed, sets and pauses in real time. This free light bar, on its own, is not remote-controlled.
Can I use it on my own without a therapist?
This tool is designed for use within EMDR therapy with a trained clinician. It is not a treatment and does not replace therapy.
Do you store any data?
No. The light bar runs entirely in your browser. It only remembers your speed, color and set length on this device.
