What are the differences between NeoRhythm and Mendi brain stimulation devices?

NeoRhythm and Mendi are two distinct brain stimulation devices designed with different technologies and purposes. NeoRhythm employs a non-invasive neuromodulation approach using PEMF (Pulsed Electromagnetic Field) technology, which is intended to encourage the creation of specific brainwave patterns to facilitate various mental states, such as relaxation, concentration, and improved sleep. It uses gesture controls for its operation and offers multiple stimulation programs. On the other hand, Mendi is a neurofeedback device that is designed to train the brain through exercises by harnessing the power of increased blood flow in the prefrontal cortex. Users control a training game using their brain activity, monitoring their progress through an accompanying app. Whereas NeoRhythm passively stimulates the brain to induce desired states, Mendi actively involves users in brain exercises with the goal of enhancing mental capabilities and cognitive function over time. Therefore, while both serve to enhance mental well-being, they differ notably in their technological approaches and user interaction.
