Mental clarity isn't just meditation or sleep. GENUS delivers 40 Hz gamma frequency stimulation — the same audio-visual rhythm MIT's Picower Institute identified as a potential lever for brain health, memory, and focus. Stop relying on vague wellness routines. GENUS uses synchronized screen flicker, isochronic audio tones, and haptic pulses — all locked to exactly 40 Hz on your iPhone's ProMotion display — to deliver clinically-inspired sensory stimulation in sessions you can do anywhere. CORE FEATURES: 40 HZ GAMMA STIMULATION The core science. Synchronized light, sound, and haptics all locked to 40 Hz — the rhythm MIT's research identified as a potential brain wellness frequency. FOUR FREQUENCY MODES Stimulate different brain states with precision-tuned sessions: 40 Hz Gamma for brain wellness and cognition, 10 Hz Alpha for relaxed focus, 6 Hz Theta for deep meditation, and 2 Hz Delta for deep sleep. CINEMATIC VISUAL THEMES Choose from animated coherence backgrounds — Heart Field's toroidal energy flow, Cymatic Bloom's rotating mandala, plus Aurora, Space, Ocean, Resonance Field, Harmonics, and more. Each one breathes with your session. BUILT-IN BREATHWORK Sync your breath with six guided patterns including Box Breathing (4-4-4-4), 4-7-8 calming breath, Triangle, Coherent 5-5 / 6-6, and a fully custom box where you set your own inhale, hold, and exhale durations. PERSONAL AMBIENT LIBRARY Layer your stimulation with pure tone, warm drone, brown/pink/white noise, rain, ocean swells, jungle ambience, or quiet cave drips. Each ambient locks to your selected frequency for perfect synchronization. STREAK TRACKING & HABIT BUILDING Build a daily session habit with automatic streak tracking, a 7-day minutes chart, full session history, and gentle daily reminders you control.
