Binaural beats are two tones you listen to simultaneously at different frequencies in each ear. The difference is barely perceptible, but your brain interprets the tones as one beat with one frequency. Your brain activity then aligns with this frequency, which is called the frequency-following effect and is why people use binaural beats to reach certain mental states. 

There are lots of different tracks, YouTube channels and apps that let you experiment with binaural beats for yourself. But the Oooo Brainwaves iPhone app stands out as a straightforward way to experience the positive effects of binaural beats, enabling you to explore various mind states with just a few taps from your iPhone. So whether you're seeking to elevate your meditation, enhance your sleep, or amplify your focus, Ooooo Brainwaves offers a unique and simple solution.

Simple, effective and free 

Ooooo Brainwaves generates specific frequencies corresponding to different brain waves, including Delta, Theta, Alpha, Beta, and Gamma. Each frequency is designed to match a particular mental state, from deep sleep to peak concentration. You can tailor your experience to your needs by selecting the right frequency. So, if you feel the effects of binaural beats, the app can become a handy tool for daily mental health and productivity management.

The app's user-friendly interface allows you to effortlessly select your preferred frequency, tone, and volume using a set of sliders. The design prioritizes simplicity, enabling you to adjust settings swiftly to match your preferences without overwhelming you with unnecessary features – a crucial aspect when seeking relaxation or focus.

For those who prefer a more tailored experience, the app also offers advanced features, such as choosing between binaural and monaural modes and adding background noise types, like white or brown noise. These features bring you a more personalized experience that can improve the effectiveness of the binaural beats.

One of the most appealing aspects of the Ooooo Brainwaves app is its efficiency. It uses minimal battery and memory, making it an excellent choice for continuous use without worrying about draining your iPhone. Additionally, the app’s compatibility with iOS devices, Macs, and even an Apple Watch app extends its usefulness, making it accessible wherever you are, whether at home or on the go.

Whether you already love using binaural beats or you're a curious newcomer, this app provides a valuable tool for mental health management and focus. Unlike many other apps in its category, Ooooo Brainwaves is free to use, with no ads, no in-app purchases, and no additional costs. This makes it accessible to anyone interested in exploring the benefits of binaural beats without the commitment.
