tDCS Brain Stimulation
Created by scientists, endorsed by doctors
Our technology
Understand how our non-invasive treatment technology works to improve mental wellness.
Flow uses advanced neurostimulation technology that's been clinically proven to help alleviate depression symptoms and help with mental wellness through non-invasive treatment.
Depression is associated with imbalances in brain activity, especially in the prefrontal cortex—a region involved in mood regulation, decision-making, and emotion processing. tDCS uses a low electrical current to modulate this brain activity.
This is believed to restore more balanced brain function, which may help alleviate depressive symptoms over time.
Non-Invasive Treatment
Unlike traditional treatments, Flow's technology is medication-free, with minimal side effects1
Transcranial Direct Current Stimulation (tDCS) can target a root mechanism of depression, but it's not a complete cure or a guaranteed solution for everyone.
Flow works on one piece of the puzzle—neural activity—but not on all causes. It's best seen as part of a broader treatment plan, often used alongside therapy, lifestyle changes, or medication. The app proposes lifestyle changes to combine with the stimulation to help create and maintain long lasting treatment success outcome.
Safety
The Flow headset has been designed and extensively tested by experts.
It is CE-certified and complies with all European and UK laws for medical devices.
It has also received the Food and Drug Administration (FDA) Breakthrough Device Designation for at-home depression treatment in the United States.
The technology Flow uses is transcranial direct current stimulation (tDCS). tDCS has been used in clinical settings for decades, and its safety and performance has been evaluated in hundreds of clinical trials. To learn more about the safety and performance of Flow in these clinical trials, visit our Research page.
It is important to always use Flow in accordance with the user manual.

Effortless set up
No serious side effects
Your safety is our priority
In over two decades of research on tDCS, no serious side effects have been reported. This strong safety profile is why Flow is approved for over-the-counter use without requiring a prescription.
Most users experience only mild, temporary side effects. These are generally well-tolerated, with most users reporting the sensations become milder over time.
You may also experience some skin irritation, such as redness or itchiness, which is common and temporary. Other users may notice tiredness, headaches, tinnitus (which is rare), or a slight increase in anxiety, especially at the start of treatment.
How Flow Compares to Other Treatments
Many people use Flow on its own or alongside other treatments.
