Close your eyes.
Phosphene turns your screen into stroboscopic light — the same idea as flashlight meditation apps, without the torch. Hold the phone to your face. The flicker does the rest.
The method
Traditional apps ask you to chase calm. This gives your brain a rhythm to lock onto.
Flickering light at around 8–10 Hz can pull visual cortex into step. With eyes closed, that often becomes phosphenes: lattices, tunnels, shifting color.
Dark room, bright screen
Lights off. Brightness up. Lie back or sit still.
Hold it near your face
Twenty to forty centimetres. The screen is the lamp.
Close your eyes
Keep them relaxed. Color and geometry happen behind the lids.
Tap anywhere to stop
Headphones optional. Escape or tap ends it instantly.
Sessions
Four lights. One screen.
Each session is a frequency envelope — not a flat strobe. Color drifts on the panel, which a flashlight cannot do.
First Light
Three minutes. Enough to know if this works for you.
Settle
Warm, slow, and low-effort. Racing thoughts have somewhere to go.
Wander
The vivid one. Ten hertz, shifting color, geometry behind the lids.
Drift
A descending pulse that lets the mind go soft with the light.
Photosensitive warning
Do not use this if you have epilepsy.
Flashing light in the 3–30 Hz range can trigger seizures in people with photosensitive epilepsy and can provoke migraine. Not for anyone under 18. If you feel unwell, stop — the effect does not linger.
