DAS, or "Disease Activity Score," is a measure of the activity of rheumatoid arthritis. Based on the work of the Department of Rheumatology at the University Medical Centre at Nigmegen (Netherlands), a validated tool (formula) was developed to evaluate and track Rheumatoid Arthritis disease activity. By measuring the tender and swollen joint counts (TJC & SJC respectively), CRP (c-reactive protein) and General Health, the DAS 28-4 gives an estimate of disease activity, while the DAS 28-3 uses just the TJC, SJC & CRP. Clinicians, rheumatologists in training, educators and researchers use this tool everyday and now you can have it readily available on your Apple mobile device.
The following formulas are free for you to try.
• DAS28-CRP (3 Variable)
• DAS/DAS28 Converter
You may use these forever and never be nagged. There are no ads. Enjoy!
If you like what you see, upgrade to the "Pro" version via one-time in-app purchase. This will unlock all remaining formulas, including:
• DAS28 (3 Variable)
• DAS-CRP (3 Variable)
• Original DAS
• Original DAS (3 Variable)

Rheumatoid Arthritis Patients Deserve Objective Measurement
If you see patients with Rheumatoid Arthritis and want to compare how they are doing, this is a great tool! It allows for measurement of several different variables in different combinations which allow calculation of the DAS Score. The DAS Score is a standard measurement of Rheumatoid Arthritis Disease Activity. This tool calculates the DAS Score quickly and efficiently and is well designed to be used in real-world settings while seeing patients as well as in clinical research settings. I highly recommend this to anyone who takes care of patients with Rheumatoid Arthritis.
The app is an excellent DAS calculator. It's easy to use and beautifully designed. Even the icon is gorgeous. I use this app in practice and highly recommend it. You get a few of the scores for free and for a ridiculously low price of a buck you can have the complete set of disease activity related scores. If you're a rheumatologist and don't have this on your iPhone, shame on you; if you can't afford it, email me and I'll buy it for you.
New version so bad
I am very disappointed with this new version. back to the old version so much better than this
