NeuralStack.io™: Focus & Sleep

Build, remix, and shape your mindset with customizable Brainwave Entrainment Stacks. Start with the included Explore Stacks, or create your own by combining multi-stage brainwave entrainment, guided breathing, and background audio elements into an integrated Stack. NeuralStack.io is designed for people who want more than pre-mixed audio tracks. Instead of locking you into pre-made sessions, NeuralStack.io gives you flexible tools to create and refine Stacks composed of multi-stage elements—so you can shape your ideal mindset for any situation.
