01
Sleep Onset
Twenty five minutes, alpha through theta into delta, brightness fading the whole way. Built precisely for this.
When: Lights off, phone propped on the pillow, screen facing the closed eyelids.
For Insomnia
Stroboscopic meditation
for insomnia.
Insomnia is rarely a problem of being unable to sleep. It is a problem of a brain that will not let go of beta-band activity when the lights go out. A slow flickering descent from alpha through theta into delta gives the cortex an external rhythm to follow at exactly the moment it needs one most.
What it actually does
Photic driving causes cortical rhythms to align with the flicker frequency over a window of seconds. Walking the flicker rate down from ten Hz to two Hz across twenty five minutes guides the EEG through the same band sequence the brain uses spontaneously during sleep onset (Loomis et al. 1937, modern equivalents in Tarokh et al. 2018). It is not a sleep aid in the pharmacological sense. It is a pacemaker.
Three protocols that fit
02
Deep Calm
Ten minute alpha to theta cycle. Useful as a wind-down forty minutes before bed, not as the bedtime session itself.
When: Earlier in the evening when you want to lower the activation level without falling asleep yet.
03
Quick Reset
When you wake at three AM and cannot get back to sleep. Five minutes is enough to break the rumination loop and re-enter the descent.
When: Middle of the night awakenings.
What to expect
Some users fall asleep mid-session on the first night. Others take a week to acclimate. The proper measure is sleep efficiency, time asleep divided by time in bed, not how fast you fall asleep on any one night. Track it for two weeks before judging.
Important caveats
- If insomnia persists past four weeks of consistent use, see a sleep physician. Untreated chronic insomnia is associated with cardiovascular risk and depression.
- Do not pair with alcohol or sedating medication without checking with a doctor. Both interfere with the same sleep architecture the protocol is trying to walk you through.
- Cover the phone if any indicator lights remain visible. Random flashes during the session disrupt the entrainment.
Frequent questions
Is this safer than sleeping pills?+
It has none of the side effect profile of benzodiazepines, z-drugs, or sedating antihistamines. The relevant risk for stroboscopic protocols is photosensitive seizure, which is rare and screened for at onboarding. For most people without that contraindication, the safety profile is closer to a hot bath than to a pill.
Does it help with middle of the night waking?+
Yes, often more than with initial sleep onset. The Quick Reset protocol breaks the rumination loop in five minutes and returns the brain to a state where the slow descent can resume on its own.
How close to my eyes should the phone be?+
Six to ten centimetres from the closed eyelids. The light should bathe the lids without producing a sharp shadow. If the screen is too far away the entrainment effect drops off.
Will my partner notice the light?+
Probably yes if they are facing you. The screen is bright at the start of the session and dims through the descent. Most users either turn away from their partner or use a sleep mask cutout. The audio binaural layer is gentle enough not to wake a sleeping partner.
