MindCrack pairs steady flame-gazing with a delayed, pitched-down echo of your own voice — a combination drawn from real perceptual research, offered here as a self-reflection practice, not a medical tool.
Consider skipping tonight if
You have epilepsy, migraines, or another condition triggered by flickering light.
You have a personal history of dissociation, psychosis, or a dissociative disorder.
You're currently in emotional distress — this app isn't a crisis tool.
While you practice
Sit somewhere quiet, comfortable, and safe. You can end the session at any time.
If your eyes strain, blink freely or close them — the practice continues either way.
Steady low-light gazing is studied as the strange-face illusion (Caputo, 2010) — it measurably shifts perception and self-experience within minutes, the same effect candle-gazing traditions like trataka have used for centuries.
Hearing your own voice delayed and pitched down draws on altered auditory-feedback research, which shows that changing how your voice sounds to you changes how "yours" it feels.

MindCrack combines two studied perceptual phenomena into one guided session: steady low-light focal gazing (related to the trataka tradition and to Caputo's strange-face-in-the-mirror research) and delayed, pitch-shifted playback of your own voice (related to altered auditory-feedback research).
It's a self-reflection prototype, not a medical device or a substitute for professional mental health care. If any part of a session feels overwhelming, stop — the flame and the echo will still be here another day.

Longer sessions intensify the experience. New to this? A shorter sit is plenty — you can always begin again.
