What is Flow?
Flow is medication-free treatment for depression.
Unlike medication, Flow works by stimulating the brain externally. No invasive procedures. No sexual side effects, no weight gain, no sedation.

Depression changes how your brain works. Flow helps change it back.
Depression is not just a chemical imbalance, it is a shift in how your brain functions. Flow uses a gentle electrical stimulation (tDCS) to target the part of the brain linked to mood.
Over time, your brain rebuilds the healthy patterns it needs.
