Ankylosing Spondylitis Symptom Tracker will allow you to assess and keep track of the severity of your symptoms, help you understand what your assessment scores mean, and allow you to share your scores with your doctor. You can back up your data to a secure cloud for use on multiple devices, but the app is fully functional offline as well.

The app uses the Bath Ankylosing Spondylitis questionnaires validated by scientists and used world-wide by rheumatologists and AS researchers. We use data from a study of nearly 3000 AS sufferers to help you interpret your symptom severity and how they compare to others’. We also use validated minimal clinically important differences to let you know if severity scores have changed significantly from last assessment. Scientific references are available in the app, but you can also contact us for statistical queries.

AS Symptom Tracker was developed independently by a group consisting of an AS sufferer, a computer programmer, a rheumatologist and a data scientist. We will never analyse or share your data without your permission, but we are interested in helping AS by contributing to research in the future. This is an area under development but pending financial support. If you share our vision to improve care of AS, please ask your local AS charity to support us or pledge a donation, so we can maintain, update and improve the app. We welcome your comments and suggestions. Please drop us a line! Thank you!
