NeuroSounds vs 4VIDA SYNC

NeuroSounds unlocks your mind's potential by using Binaural Beats - an auditory phenomenon where slightly different frequencies played in each ear create a perceived third, rhythmic beat. Your brain naturally aligns its electrical activity to this frequency - a process called “Neural Entrainment”. This gently encourages your brainwaves to shift towards desired states, supporting your cognitive and emotional well-being without conscious effort. -- -- -- -- Mental States NeuroSounds allows you to choose between the following specific Mental States, for your desired outcome: • Deep Sleep & Recovery (Delta) Use these frequencies when you need deep physical healing, total recovery from exhaustion, and restorative rest. • Deep Relax & Meditate (Theta) Use these frequencies to cultivate inner calm, deepen a mindfulness practice, or access quiet creative insight. • Relax & Unwind (Alpha) Use these frequencies to clear your head, enjoy light reading, or comfortably absorb new concepts. • Calm Focus & Study (Low Beta) Use these frequencies for technical learning, long reading sessions, and steady, uninterrupted study. • Alert & Active (Mid Beta) Use these frequencies when tackling demanding workloads, writing code, analyzing data, or managing complex active tasks. • Focus & Insight (Gamma) Use these frequencies for high-level problem solving, advanced pattern recognition, and breakthrough creative insights. -- -- -- -- Mental Presets NeuroSounds also offers the following selection of Presets for those who conveniently need to access a journey for a desired outcome: • Drift To Sleep Ideal for bedtime routines, late-night restlessness, or recovering from sleep disruption, this preset is designed to ease overactive night-time thoughts toward physical heaviness and deep sleep. Place your device nearby, close your eyes, and let the acoustic progression guide you into undisturbed, high-quality rest. • Meditative Cycle Ideal for midday resets, stress relief, and mindfulness practice, this cycle helps ease mental tension, restore emotional equilibrium, and enhance intrinsic self-awareness. You exit the session with a centered, resilient mind, recharged with calm focus and ready to re-engage with your day. • Cognitive Cycle Designed for long study sessions, complex problem solving, and intensive project execution, this cycle helps manage mental fatigue by matching your body’s natural BRAC physiological rhythm. It supports focused output while building in structured cognitive recovery, keeping you sharp, productive, and mentally sustainable throughout the day. • Calm Down From The Stress Ideal for high-stress work moments, post-confrontation resets, or easing intense overthinking, this preset helps bring you back to a state of calm productivity. It works to clear the mental static and physical tightness caused by high stress, supporting emotional control, objective decision-making, and composed focus so you can navigate the rest of your day with ease. • Push Through The Stress Ideal for high-pressure deadlines, emergency troubleshooting, or critical rapid-response scenarios, this preset helps channel nervous energy into high-throughput execution. It supports redirecting overwhelming stress into hyper-focused insight, rapid pattern recognition, and decisive action, helping you power through critical bottlenecks when failure is not an option. • Hyper Focus Cycle Designed for long-form deep work, complex architecture, and intensive project execution, this cycle structures a multi-hour focus session into a self-sustaining loop. Because it supports sustained productivity across both its ascent and descent phases while demanding heavy metabolic energy during the Gamma peak, Hyper Focus Cycle should be used strategically, no more than once or twice a day, to deliver maximum output while safeguarding long-term stamina.

Sleep, focus, deep calm — with sound generated live from your heartbeat. 4VIDA SYNC doesn't play back a finished file. Every session is created in the moment you hear it — like a live concert instead of a recording. Via Apple Watch, the sound follows your heart rate variability (HRV) and adapts to your nervous system in real time. YOUR BIO-TONE Before your session, 4VIDA SYNC runs a sweep calibration to find the frequency your nervous system responds to most clearly — your vital signature. From it emerges your personal bio-tone, the root note of every soundscape. Same mode, different person, different sound. SMART SESSIONS — SIX MODES WITH LIVE ADAPTATION • REST — drift into sleep • RECOVER — deep regeneration • RELEASE — let go • FOCUS — clear concentration • CONNECT — present and grounded • ACTIVATE — awake and ready With Apple Watch, the audio engine continuously adapts to your heart rate variability during the session — like a good running shoe adapting to your foot. ELECTRIC MOODS — SOUND FOR ALONGSIDE Four moods without ritual: FOCUS, RELAX, SLEEP and MOVE. Switch on, carry on — with a sleep timer for the night. SHARED SESSIONS Listen together: in sync at the same time, with the same reference tone. Or start a partner session with an invite code — two people, even across any distance. WHAT TO EXPECT • Your sound is generated live on your device — no streams, no sample loops • Apple Watch optional, recommended for live adaptation • Headphones recommended — the stereo texture only unfolds on two channels • Sleep timer, "Continue where you left off", Siri shortcut • Dynamic Island + Lock Screen controls • Ambient videos as gentle visual companions YOUR DATA Your Apple Health data stays in Apple Health.

Session results are stored encrypted in your account — export them anytime, or delete your account and data right in the app. PRICE Start free. 4VIDA Plus unlocks everything — 7-day free trial.
