Zeus App: Your companion for restful, snore-free sleep. Discover the power of Zeus, the clinically proven anti-snoring device, designed to help you and your loved ones experience uninterrupted sleep. The Zeus companion app enhances your journey by providing seamless device management, insightful sleep tracking, and personalised guidance—all at your fingertips. Why we know what we’re talking about: Zeus is the result of 15 years of research, development and clinical validation alongside King’s College London, Guys and St Thomas’s NHS Foundation Trust and Morgan Innovation & Technology into Transcutaneous Electrical Nerve Stimulation (TENS) technology. The Zeus device targets the hypoglossal nerve through gentle electrical pulses, improving airway muscle tone during sleep. This new application of TENS significantly reduces snoring whilst being lightweight, silent and sleek. From our Zeus community: ‘In a couple of words, life changing. The difference the Zeus device made is genuinely incredible. I have had years of investigations following the contraction Lyme disease and all have focused on chronic effects directly from Lymes, however it now seems that at the same time snoring / sleep Apnoea have been significant contributory factor. Thank you so much for putting your time, knowledge and skills into creating this device, if my experience is anything to go by many, many people will have vastly improved quality of life as a result of this device. I will not sleep without it again’. First use: You need to pair your Zeus device with this app to monitor your Zeus stimulation levels, use your snore record to monitor how refreshed you feel and see how many hours of refreshed sleep you (and maybe your partner too!) have had on your very own Snoreboard. Key features and benefits: - Sleep refreshed – alleviate snoring now - Your very own Snoreboard - A comprehensive data hub showcasing your progress and proving Zeus works. Visualise improvements, spot snore-free progress, and celebrate sleep milestones. - Exclusive knowledge library - Access a rich content library featuring expert advice, video guides, and sleep health articles. - Smart sleep tracking and device usage: receive daily data feedback on how long you used Zeus and its stimulation setting. Rate your sleep quality and assess your partner’s satisfaction—turning subjective feedback into tangible progress. Guidance to help you: - Effortless registration - Set up your account with ease, capturing both essential details and insights into your snoring story to tailor your Zeus experience. - Intuitive onboarding - New users receive step-by-step guidance, including charging instructions, Bluetooth pairing, getting the most out of your Snoreboard, and engaging video tutorials.
