Melon is a headband and mobile app duo that tracks and helps you improve your focus in relation to your activity, your environment, your emotions, and any other behavior you want to track. The Melon headband is a wireless brain-sensing device that uses EEG (electroencephalography) to measure your brain activity. From this activity, our algorithms detect your focus, and we use that data to give you personalized feedback on how to improve. We have partnered with a top producer of EEG signal processing chips to access the best available algorithms for mental state detection. EEG has been used widely in the medical and research fields for over a century, and we're excited to make the technology available to you through Melon.
