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.
The three categories
Free browser tools
Web pages that generate a moving dot or alternating tones, usually with no account required. They are genuinely useful, cost nothing, and are the right answer for a clinician who works face-to-face with one device. Their limits show up in remote work: the client either has to open the page themselves and control it, or you have to send the stimulation through your video platform, which degrades timing.
Therapist-controlled apps
Installed apps where the therapist holds the controls and — for remote sessions — the stimulation is generated on the client's own device. This category exists to solve one problem: keeping control with the clinician while keeping the signal off the video connection. EMDR Mobile is in this category.
Full practice platforms
Systems that combine BLS with video conferencing, scheduling, notes and billing. If you want one subscription covering your whole practice, this is the category to look at. The trade-off is that you also adopt their video platform and their record-keeping, which is a bigger decision than choosing a stimulation tool.
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 settings and subscription to follow your account.
- You want in-person sessions to work without an internet connection.
- You do not want the client to pay or subscribe — client mode 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 visual BLS as your primary modality for most of your caseload.
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.
