Questions

Why does Sychedelic combine tDCS, binaural beats, and PPG rather than using just one technology?

Each technology addresses a different part of the cognitive performance problem. Binaural beats prime brainwave states for focus or relaxation. tDCS modulates the excitability of the prefrontal cortex to support sustained cognitive work. PPG reads HRV in real time to confirm your nervous system is in the right state before stimulation begins. Together they create a closed-loop system; individually, each has significant limitations.

What does the PPG sensor in Sychedelic actually measure?

The PPG (photoplethysmography) sensor uses light to detect blood volume changes with each heartbeat near the ear. From this signal, Sychedelic derives heart rate variability metrics — including RMSSD and LF/HF ratio — which reflect the balance between your sympathetic and parasympathetic nervous systems. This tells the device whether you are in a state suitable for tDCS stimulation.

How long does a Sychedelic session take and when do the effects begin?

A standard session runs 20 minutes, with tDCS Boost activating around minute 10 once baseline HRV confirms readiness. The post-stimulation performance window — where focus effects are most pronounced — lasts approximately 20 to 90 minutes. Many users notice calming or focusing effects within the session itself, though consistent multi-session use produces more durable gains.
