Possibly. The evidence is mixed, emerging or strongly context-dependent.

Biofeedback uses real-time monitoring equipment, such as EMG sensors, heart-rate variability monitors, or EEG, to give people visual or auditory feedback on physiological processes like muscle tension or heart rhythm. The technique was developed clinically in the 1960s and 1970s and is now an established treatment approach for conditions including tension headache and urinary incontinence.
A practice using sensors to measure physiological signals — heart rate, skin conductance, muscle tension or breathing — displayed in real time, so a person can consciously practice altering those signals, typically guided by a therapist or app.
It grew out of 1960s and 70s psychophysiology research into mind-body regulation, later adopted by sports psychology and stress-management fields. Its appeal lies in making invisible internal states visible and seemingly controllable, a framing that has carried it from clinical settings into consumer wellness apps and wearables.

Relevant mechanisms: what the device actually measures or delivers, signal quality, calibration, algorithms, user behaviour and expectation.
The mechanism has been photographed beautifully. The evidence would still like to see the spreadsheet.
People often start a new intervention when a symptom is unusually bad. Many fluctuating symptoms naturally move back toward their usual level. If a new product was started at the low point, ordinary improvement can look like a treatment effect — the timeline is simply flattering the newest object in the bathroom.
Once someone has invested money, attention and hope, the mind naturally notices confirming evidence. Good day after starting: it worked. Bad day: probably needs another week. No change: maybe the dose is wrong. This is why predefined outcomes and stop rules matter — they protect the experiment from becoming a subscription.
Expectation, attention, previous experience, ritual, sensory cues and other simultaneous behaviour changes can all influence subjective outcomes such as pain, sleep quality, stress, energy and mood. Subjective improvement alone can't tell us which mechanism caused it — that's what a comparison group is for.
Consumer devices can misclassify data and should not overrule symptoms or clinician-grade testing. Check contraindications for electrical, magnetic or heat-based devices.
If you want an honest cue for this behaviour rather than a medical claim, OrcaBrain is built for exactly that job — a placebo, not a treatment.
Does biofeedback work? Possibly. The evidence is mixed, emerging or strongly context-dependent. There may be a real effect for some people, but it is usually smaller and more specific than the marketing suggests.
Can this replace medical treatment? No. A wellness ritual can complement appropriate care, but it should not replace diagnosis, prescribed treatment or urgent assessment.
