Welcome to Cerebyte, the neuroscience based audio wellness app designed to help you shift your mind into specific mental states using real brainwave recordings. In a market flooded with generic meditation apps, synthesized binaural beats, and basic sleep sounds, Cerebyte offers a radically different approach. We do not just give you calming music for sleep. We provide sound experiences modulated by the actual electrical activity of the human brain. The human brain produces electrical waves that correspond to different states of consciousness. For the first time, these waves have been recorded and translated into audio. We call them Cerebytes. When you listen, you are hearing the audio shaped by the real brain activity associated with the exact state you want to move toward, whether that is deep sleep, absolute focus, or anxiety reduction. Direct Brain to Brain Sound Technology is designed to help your brain shift into the state you need. What if you could listen to the sound of the state itself? Whether you are seeking a guided meditation app, study music for memory retention, or a tool to support brain training, Cerebyte adapts to your unique needs. During onboarding, you are prompted to select your primary goals to personalize your experience. Our library includes dedicated states for Anxiety Reduction, Craving Control, Creative Flow, Deep Sleep, Energize, Experimental, Focus, Meditative, Motivation, and Relaxation. If you are looking for an app to help with insomnia, improve your sleep cycle, or act as a sleep tracker companion, Cerebyte provides audio crafted from a real sleeping brain rhythm. Cerebyte is built to support your productivity and mental health throughout your entire day. You can indicate exactly when you need your desired state, choosing from Morning, Afternoon, Evening, Before Bed, or In Urgent Moments. Explore our core features: • The Wake Up Alarm: Set up your Wake up alarm and select a soundbyte to wake up to. Start your morning in a state of calm or elevate your brain right out of a dream. • Soundscapes: Initiate the creation of a new soundscape and personalize it to your liking. You can name your soundscape, select a cover picture, and choose custom colors. • My Sessions: Easily view your previously generated or saved sessions. Add your top tracks to your Favorites for quick access. • Guest Access: You can enter as a guest to try the app before committing to an account. If you are tired of standard sleep sounds, generic white noise for babies, or traditional mindfulness apps that fail to hold your attention, Cerebyte provides a scientifically grounded alternative. It serves as an excellent companion for those needing deep sleep music, concentration music for deep work, or relaxation music for anxiety. Our users find it to be an incredible asset for productivity, flow, and overall mental wellness. While we offer a free experience, a paywall screen invites you to upgrade to the premium Cerebyte Gold experience. With a Gold subscription, you unlock full access to the EEG state library. You receive full EEG database access, all brain states unlocked, unlimited sequence creation, early access to new cerebytes, and no interruptions. You can start a 7-Day Free Trial and cancel anytime. We believe in giving back to the scientific community. A percentage of the profits of this App goes to the Charity TeleEEG at www.teleeeg.org. By improving your own brain states, you are also helping support clinical EEG access worldwide. Download Cerebyte today to experience the true sound of your brain.
