The isi App is a holistic tool designed specifically for managing premenstrual syndrome (PMS) directly from your iPhone. It encompasses a variety of disciplines including medicine, physiotherapy, nutrition, pain management, yoga, psychology, and relaxation techniques to provide a well-rounded support system. Currently, access to the app is limited to invitations or participation in an ongoing study, making it a unique resource for users dealing with PMS.

One of the key features of the isi App is its multimodal approach, which encourages users to observe and document their symptoms, events, influencing factors, and treatments through a specialized diary. The app offers intelligent diary evaluations that help users become experts in their individual challenges by suggesting scientifically-backed learning modules tailored to their needs. Additionally, the isi App creates personalized daily plans based on these evaluations, providing interactive exercises and a customized SOS plan for better management of PMS symptoms.
