Thrive: Mental Wellbeing is an evidence-based app designed to help users prevent and manage stress, anxiety, and related conditions. Created in the UK by specialists with extensive clinical experience, Thrive employs clinically proven techniques to support users in living a happier, more relaxed, and stress-free life. The app is available as part of a suite of services and offered in partnership with companies, charities, insurers, and other organisations. Although the app is free to use, access requires a code from one of Thrive's partner organisations. Thrive is suitable for adults, teenagers, and older adults seeking to improve their mental wellbeing. It offers a range of personalised features for healthy living, relaxation techniques, and mental health management. The app helps users monitor their mood and provides accessible tools such as meditation and breathing exercises. These techniques, along with deep muscle relaxation, have been shown to help individuals better manage stressful situations with practice. One of the standout features of Thrive is its thought trainer programme, based on cognitive behavioural therapy (CBT). This programme is designed to assist users in managing negative thoughts effectively. Thrive is flexible, with no rigid rules for usage, allowing individuals to engage with the app for as little as three minutes before a stressful situation or more regularly to build resilience and keep stress levels under control. Thrive is backed by thousands of users worldwide, and its effectiveness is continually improved through a dedicated research programme with the University of Roehampton. By transforming practices traditionally used in hospitals and clinics into a fun, game-based format, Thrive makes it easier and more engaging for users to incorporate these techniques into their daily lives. For those looking for a reliable app to manage stress and anxiety, Thrive provides a comprehensive, scientifically-backed approach. It offers personalised support and tools tailored to each user's needs, helping them achieve and maintain better mental wellbeing. Thrive is available for download via the Apple App Store and Google Play Store, making it accessible to a wide audience seeking improved mental health and overall wellness.
