About this app

**With this app, you can easily generate pure tones that help stimulate focus, meditation, or deep relaxation.**

---

**⚠️ Very Important**
• Use headphones for the best sound experience.

• Do not use this app while driving or operating heavy machinery.

• Protect your hearing — high volume is not necessary.

---

**🎛️ Create and Customize Your Own Frequencies**

Easily generate and save your own frequencies using two independent oscillators.
Control them with horizontal sliders, fine-tune with adjustment buttons, or tap the frequency values to input precise numbers (supports two decimal places, e.g., 125.65 Hz).

All sounds are generated **in real-time** — not pre-recorded — allowing uninterrupted playback for as long as you wish.

---

**🧠 How It Works**

Binaural beats are a perceptual audio illusion that occurs when two slightly different frequencies are played separately in each ear. Your brain interprets the frequency difference as a rhythmic beat, which can influence your mental state.

For example, playing 300 Hz in one ear and 310 Hz in the other creates a perceived beat of 10 Hz — a frequency associated with relaxation or meditation.

For best results, always use headphones at a low to moderate volume. The binaural effect is only noticeable when both ears are engaged.

**🎧 Audio Tips**

• Use headphones for a proper binaural experience.
• The app’s volume slider is separate from your device’s system volume — adjust both if needed.
• High volume is not required for effective results.

**⚙️ Android Compatibility Note**

Newer Android versions may limit background processes to save battery and optimize performance.
Because this app uses real-time audio synthesis, this can affect audio playback.
To prevent interruptions, follow the instructions on:

Ratings and reviews

Extremely useful, although it often glitches or skips or something and sounds like a loop... Might have something to do with sound wave dynamics, I don't know. Lately it keeps shutting itself off whenever I leave the app, and won't run in the background... in addition, the notification won't go away, saying that brain waves are running when they're not. Please fix this.

I use this app to send Delta Waves "Sleep" preset to my BlueTooth earbuds while I sleep. I really want "Brown Noise" (Similar to "White Noise") mixed in, and I found that I can run the "White Noise Lite" by TMSOFT app with the "Brown Noise" preset at the same time. It is tough to get the relative volume of the two apps to my liking, but I live with it. Having a Brown / white / pink noise option built into this app would be a great enhancement. Problem 1: This app consumes a lot of battery. Even though I am using Bluetooth (not earbuds), the battery level goes from 80% to 43% % in 7 hours. I don't like to leave my phone charging overnight because I want to avoid letting the charge level exceed 80% to preserve battery health. Either this app is wastefully sending the low frequency sounds to the headphone jack, or the ads are consuming too much power. Note that I have the White Noise App running at the same time (with ads), and it does not consume nearly as much battery. Problem 2: Since I am running two apps at the same time, I noticed that I can't hit the "back" key on my Galaxy Note 5, without causing the "Brain Waves" app to stop playing. I consider this an annoying bug. My workaround is to start the "White Noise Lite" app first (which does not stop playing when I hit the "back" key). Then I start the "Brain Waves" app. Was really frustrating, until I figured out that I have to launch the apps in a specific order. The "Brain Waves" app will stop playing in other situations way too easily. Problem 3: I tried manually setting the frequencies 57hz and 53hz. This is really difficult given the way the user interface has you adjust each ear separately, and the slider bar is way too sensitive (useless), and the +/- buttons, which increase the frequency by 0.01 hz (are not sensitive enough). Yes you can save a custom preset once you find one you find one you like. Still, it should not be so hard to tweak the left vs. right ear frequencies. I gave up and started using Delta wave "Sleep" preset which uses 75hz and 73hz. I would prefer to be able to tweak the frequencies, but the frustration factor when you are trying to relax for sleep is ironic.

Would give 4 1/2 stars. Not enough presets compared with similar aps. I like that the sound is being generated though as opposed to a loop. That can really take you out of it if it's done poorly. Round out the presets and it'd be 5 stars easily. Love the simple interface that allows for detailed control despite it's simplicity. When it comes to this woo woo stuff I tend to trust a slick streamlined simple app far more than one that tries to look pretty and shiny with unnecessary graphics.
