Bumble BLS B-Pulse vs.
an App.

The B-Pulse is a $209 Bluetooth wearable for EMDR bilateral stimulation. TheraJoy turns Joy-Con controllers you may already own into a precise haptic BLS tool — for $79/yr.

What the B-Pulse is

The Bumble BLS B-Pulse is a Bluetooth wrist-worn device designed specifically for bilateral stimulation in EMDR therapy. At $209, it's a dedicated piece of hardware with EMDR session profiles built into a companion app, sand and waterproof construction, and a wrist-worn form factor that keeps the client's hands free during sessions.

It's a thoughtful product for a specific use case. The question is whether that use case matches how you actually work.

Where the B-Pulse wins

Wrist-worn, hands-free. The B-Pulse straps to the wrist — the client holds nothing. Some clients prefer this, especially during more somatic processing phases of EMDR where holding objects can feel distracting. This is a genuine differentiator that Joy-Con controllers can't match.

Waterproof. Sand and water resistance opens use cases that aren't possible with electronics — outdoor sessions, clients who sweat heavily, or settings where hardware needs to be wiped down between uses.

No ongoing software cost. After the $209 upfront, there's no annual subscription. Over several years this math shifts in the B-Pulse's favor for in-office solo use.

Where TheraJoy wins

Teletherapy works out of the box. With TheraJoy, remote clients download the app for free and join a session via shared code. To run remote sessions with the B-Pulse, each client would need to own their own $209 device — a significant barrier.

Lower barrier to start. Joy-Con controllers are $80 for a pair, and many clients already own them from a Nintendo Switch. The cost to try TheraJoy is nothing — free download, 7-day trial. You find out if it works before spending a dollar.

No single point of hardware failure. If a B-Pulse is lost, damaged, or forgotten by a client, you're out $209 and the session can't proceed. Joy-Con controllers are more widely available, and the app itself is always re-downloadable.

Honest take: If you run exclusively in-office sessions and want a client to hold nothing during processing, the B-Pulse's wrist-worn form is a real advantage. If you do any teletherapy, or want clients to be able to practice between sessions without buying dedicated hardware, TheraJoy is the practical choice.

Try free before buying any hardware.
