40 Hz Gamma Brain Stimulation

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

40 Hz gamma stimulation with 5 audio modes, visual flicker, session history, and Apple Health integration. Gamma Care delivers non-invasive 40 Hz gamma frequency stimulation through sound and optional light flicker, based on groundbreaking research from MIT's Picower Institute for Learning and Memory. WHAT IS 40 HZ GAMMA STIMULATION? Gamma oscillations are natural brain rhythms critical for attention, memory, and perception. Research led by Professor at MIT has shown that non-invasive 40 Hz light and sound stimulation can: • Reduce amyloid-β and tau protein buildup in Alzheimer's mouse models • Activate the brain's glymphatic clearance system • Slow brain atrophy in mild Alzheimer's patients (Phase 2A clinical trial) A large Phase III clinical trial (HOPE, ~670 participants) is currently underway with results expected in 2026. AUDIO MODES • Pure Tone — Direct 40 Hz sine wave, closest to the original MIT research method • Isochronal — 250 Hz carrier with 40 Hz pulse modulation, more comfortable for extended listening • Harmonic (Pro) — Rich multi-harmonic carrier for a warmer, fuller tone • Binaural (Pro) — Left 200 Hz / Right 240 Hz creates a perceived 40 Hz beat (headphones required) • Nature (Pro) — Rain, ocean, and forest soundscapes with subtle 40 Hz modulation FEATURES • Adjustable session timer with countdown display • Background playback — works with screen locked • Fade in/out for gentle audio transitions • Optional 40 Hz visual flicker with adjustable brightness • Session history tracking with streak counter • Daily reminder notifications PRO FEATURES (One-Time Purchase) • Harmonic, Binaural, and Nature audio modes • Background soundscapes: white, pink, and brown noise • Custom session duration (5–120 minutes) • Full session history (free: 7 days) • Session notes and journal • Apple Health integration (mindfulness minutes) SAFETY • Visual flicker is OFF by default and requires explicit acknowledgment of epilepsy risk before enabling • This app is NOT a medical device and does not diagnose, treat, cure, or prevent any disease • Consult your healthcare provider before use, especially if you have epilepsy or seizure disorders IMPORTANT DISCLAIMER GammaCare is a wellness tool based on published scientific research. It is not FDA-approved and should not replace professional medical advice or treatment. Individual results may vary.
