AS Symptom Tracker app for iPhone and iPad

This free app lets you keep track of your symptoms and helps you understand what your assessment scores mean. You can also share your scores with your doctor.

The assessment scores used by the app are recognised by rheumatologists world-wide. We use data from a study of nearly 3000 people with AS to help you compare your scores with others. We also use validated MCID (minimal clinically important differences) so that you can know if your scores have changed significantly from the last assessment.

We are interested in helping to improve management of AS by contributing to research. This is an area under development. We welcome your feedback and suggestions.

- Assess how severe your symptoms are
