## What is Gamma Care?

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.
