How to Choose an EMDR BLS Tool
There are more BLS tools available now than most therapists have time to trial. This is a criteria-first guide to choosing one — what actually differentiates them, which questions to ask before you commit, and an honest account of where EMDR Mobile fits and where it does not. If you only need something for face-to-face work today, try the free online BLS tool first; for the remote-session audio details see EMDR via Zoom and telehealth, and for hardware comparisons EMDR light bar alternatives.
The categories in brief
Tools fall into four groups: dedicated hardware, free browser tools, online platforms where the client joins through a link, and native apps. The side-by-side comparison, with a table and each vendor's own stated features and prices, is in EMDR light bar alternatives. This page is the checklist you apply to any of them.
Criteria that actually matter
- Where the stimulation is generated in remote sessions. The single most important question. If it is produced on your machine and streamed through video conferencing, the timing is at the mercy of the connection. If it is produced locally on the client's device, it is not.
- Who holds the controls. If the client has to make each adjustment themselves, every speed change becomes an interruption during Phase 4.
- What the client has to do. Any friction here — creating an account, entering payment details, installing something complicated — lands on a client who may already be anxious about the session.
- Offline capability. Clinic wifi fails. A tool that needs a connection for in-person work will eventually fail during a session.
- Modalities offered. Auditory alone covers most remote work; visual and tactile matter if your caseload needs them.
- Parameter range. Speed and set length are table stakes; tone or pitch control is not universal and matters more than it sounds for clients who find bright tones aversive.
- Data handling. Ask specifically whether session audio or content is stored, where servers are located, and whether the answer satisfies your regulator. Get it in writing.
- Cross-platform coverage. If you move between a clinic tablet and a home desktop, check whether one subscription covers both or whether desktop is charged separately.
- Cost model. Per-therapist, per-client, or per-platform pricing produce very different bills at the end of a year.
Questions to ask any vendor before subscribing
- In a remote session, is the audio generated on my client's device or streamed from mine?
- Does my client need to pay, subscribe, or create an account?
- Is any session content, audio or client identifying data stored on your servers?
- Does the subscription cover desktop as well as mobile?
- Can I trial it in real sessions before paying, and how do I cancel?
- What happens mid-session if my connection drops?
Where EMDR Mobile fits
Being specific about our own tool is more useful than being enthusiastic about it.
Good fit if
- You run online sessions and want the stimulation on the client's device with the controls on yours.
- You work across several devices or clinics and want one subscription to cover iOS, iPadOS, Android, macOS and Windows.
- You want in-person sessions to work without an internet connection.
- You do not want the client to pay or subscribe: the client app is free.
- You need tone control alongside speed, for clients sensitive to bright tones.
Probably not the right tool if
- You work exclusively face-to-face with one device and one pair of headphones — a free browser tool will do this perfectly well.
- You want scheduling, notes and billing in the same subscription; that is a practice platform, not this.
- Your clients cannot or will not install an app on their own device.
- You need tactile BLS: the therapist panel has no tactile option.
How to run a real trial
Feature lists do not predict how a tool behaves in Phase 4. If you are testing one, use the trial period on actual sessions rather than on yourself, and deliberately test the failure cases: change the speed mid-set and see whether the client notices the mechanics; drop your wifi and see what happens; run one session on your phone and the next on desktop. A week of ordinary clinical use tells you more than any comparison table, including this one.
The EMDR Mobile app
Try it alongside the criteria above. EMDR Mobile is a therapist-controlled bilateral stimulation app for clinicians trained in EMDR. The client app is free, and for online sessions the stimulus plays on the client's own device while you control it.
