Gamma Care vs Pure Phase

GammaCare brings 40 Hz gamma stimulation — the approach studied at MIT's Picower Institute — to your iPhone. Precisely generated 40 Hz audio, optional synchronized screen flicker, a daily routine, and clear consistency tracking. AUDIO MODES • Pure Tone — a clean 40 Hz sine wave, closest to the research setup (headphones recommended) • Isochronal — a 250 Hz carrier pulsed at 40 Hz, easier on the ears • Click Train — the same stimulus type used in MIT GENUS clinical trials, free for everyone (new in 3.0) • Harmonic, Binaural, and Nature modes (Pro) BUILD A DAILY HABIT • Session timer with streak tracking and session history • Daily Protocol (Pro): follow the GENUS-style 60-minute daily target and see your 7-day adherence at a glance (new) • Live Activity countdown on the Lock Screen and in the Dynamic Island (Pro, new) • Home Screen widget with your streak and daily progress ring (Pro, new) • Daily reminders, session notes (Pro), Apple Health export (Pro) DESIGNED FOR EVERYONE • Large Text mode for easier reading (new) • Full VoiceOver support • English, Simplified & Traditional Chinese, Japanese, French, Spanish, German, Korean, and Portuguese OPTIONAL 40 Hz LIGHT Screen flicker is off by default and always shows a safety warning before enabling. Flashing light can trigger seizures in people with photosensitive epilepsy. IMPORTANT GammaCare is a wellness app, not a medical device. It does not diagnose, treat, cure, or prevent any disease. Research on 40 Hz stimulation is ongoing and results may vary. Always consult your doctor, especially regarding Alzheimer's or other neurological conditions. GammaCare Pro is a one-time purchase that unlocks all Pro features above. No account, no subscription, no ads.

Pure Phase uses synchronized light, sound, and breath to guide you into focused, calm, or sleep states — without subscriptions, accounts, narration, or bloat. Tap to begin. Hold to tune. That's the whole interface. THREE SCIENCE-GROUNDED STATES FOCUS — 40Hz gamma frequency, synchronized light and isochronic audio. Associated with peak mental clarity. The subject of ongoing clinical research at MIT and elsewhere. CALM — 10Hz alpha frequency. One of the most consistently documented frequencies in relaxation and stress research. Ideal for unwinding, creative work, or transition between tasks. SLEEP — 2Hz delta frequency. Use with eyes closed and torch enabled. The flashlight pulses at the session frequency through your eyelids — no screen required. BREATHE — GUIDED BREATHWORK A fourth mode with no flicker — just a breathing ring that expands and contracts to pace your breath. Choose from Coherence (6 breaths per minute, the HRV resonance frequency), 4-7-8, Box breathing, or Slow Wave. Or build your own pattern in Advanced settings. ISOCHRONIC AUDIO A warm audible carrier tone pulses at the brainwave frequency, synchronized frame-by-frame with the visual flicker. Underneath, a procedurally generated ambient texture — pink noise, brown noise, or sustained drone — provides continuity and masks environmental sound. Everything is generated on-device. No audio files. DRIFT & BLOOM New psychoacoustic modes for headphones. Three synthesis layers create auditory depth and slow movement through pure tones — a breathing carrier, a drifting stereo field, and optional harmonic shimmer. DRIFT pairs them with a pure black canvas. BLOOM pairs them with a slow generative visual field that breathes and shifts color in sync with the audio. Non-stroboscopic — accessible to anyone who can't tolerate the entrainment modes. ADVANCED For users who know what they want: Theta, SMR, PRISM, and Void states, a custom Hz slider from 0.5 to 40Hz, custom breath timing with independent inhale, hold, and exhale controls, and carrier frequency selection. Clearly labeled as exploratory. PURE PHASE IS FREE No subscription. No account. No guided narration. No content library. No streak tracking. No ads. No data collection of any kind. Everything runs on your device. Pure Phase uses rapid rhythmic light pulses. Do not use if you are photosensitive or have a history of epilepsy or seizure disorders. Always use in a safe, seated, stationary environment. Not a medical device.
