Happy Electronics develops and manufactures electronics for sleep and biofeedback — bedside sleep monitors, light-and-sound mind machines and pulse oximeters — together with the mobile apps that read them. Our motto is to create products that improve the quality of life: better sleep and less stress. We are a Czech team of programmers and electronics developers and we have been shipping our own hardware worldwide since 2007.
