I have been trying quite a few apps for the NeuroSky mindwave and very few are as well executed and useful as the ZenZone. It’s very well crafted and by combining neurofeedback and hypnosis-like approaches I believe it hits the spot. Very good value for money and excellent range of additional sessions that keep been added up at a reasonable price. My experience with customer support was absolutely fantastic. Very quick and responsive and giving a lot of details and information about the utilisation of the App. Overall I thoroughly recommend it.
