Sphere Neurofeedback & Emotion
Read full descriptionHide full description
Sphere uses sound to help you regulate your emotions and nervous system. Most emotional health tools ask you to think your way calm. Sphere works differently. Guided sound sessions use patented digitised neurofeedback to train the regulation itself, so it holds when you need it. HOW IT WORKS Sphere delivers Neurofeedback through sound alone. No headset, no wearable, no clinic appointment. Put your headphones in and start a session. One 20 minute session a week. Not a daily habit to keep up with, not another streak to break. You log how you feel before and after, and over time you can see how your patterns are shifting. WHAT YOU GET Guided sound sessions One structured neurofeedback session a week, for stress, emotional overwhelm, low mood and difficulty settling at night. Emotional tracking Rate your state before and after each session and watch the change build over time. Mood diary Capture what happened, what set it off and what helped, so you start to recognise your own triggers. WHO SPHERE IS FOR Emotional health runs through every health journey. Sphere was built for people managing something else at the same time: a new diagnosis, a weight management programme, a long-term condition, a demanding job, or a period where everything simply landed at once. If you are eating in response to stress rather than hunger, lying awake with your mind running, or finding that your emotional responses feel bigger than the situation deserves, Sphere was designed for you. BEHIND SPHERE Sphere is built by Stress Point Health, a UK digital health company. The underlying digitised Neurofeedback technology was granted a UK patent in April 2025, with applications pending in the EU, US and UAE. YOUR PRIVACY Your sessions and diary entries belong to you. We do not sell your personal data. Full detail in our privacy policy. IMPORTANT Sphere supports emotional regulation and wellbeing. It is not intended to diagnose, treat, cure or prevent any medical condition, and it is not a substitute for professional medical or psychological care.
