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.
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.

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.
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.
TheraJoy is free to download. Full 7-day trial, no credit card. Run a real session and decide.
