The Calm Gut: IBS Hypnotherapy is a free mobile application designed for iPhone users seeking long-term relief from Irritable Bowel Syndrome (IBS) symptoms. This evidence-based toolkit combines gut-directed hypnotherapy, Cognitive Behavioural Therapy (CBT), and mindfulness techniques to address the miscommunication between the brain and gut. Developed by psychotherapist Jayne Corner, the app offers over 90 audio sessions aimed at self-managing IBS symptoms without the need for restrictive diets.

Key features include targeted hypnotherapy sessions, affirmations, breathing exercises, and mindfulness techniques. Users can explore an audio blog on IBS-related topics and participate in programs and challenges to enhance their quality of life. The app also allows for offline listening, playlist creation, and features an in-app community. A 7-day free trial provides open access to the library, making it easy for users to evaluate the app's effectiveness for their needs.
