What's New in JointSignal

1.5

October 31, 2026

• Blood results now cover the whole monitoring panel: liver, kidney and the full blood count, including haematocrit, MCV, MCH and the white-cell differential. • Enter results the way the lab prints them, including "less than" and "more than" results such as a CRP under 2, with reference ranges as the lab writes them, and choose the unit your lab uses. • When CRP comes back as "less than", DAS28 is shown as a ceiling (≤) rather than an exact score. • The report gives blood results a page of their own, with your latest three tests side by side. • Fixed: a second blood test on the same date is no longer saved twice, and a value over 1,000 is no longer lost when edited.

User reviews

Finally a place for everything

Before Joint signal I was constantly switching between notes on my phone and random other apps. Now I can finally have all of my data in one place. I really like the joint count feature as well as being able to see patterns in my symptoms to inform my rheumatologist.

Excellent RA symptom tracker

An excellent, easy to use symptom tracker built specifically for RA. Great to have apple Health integration and reminders for logging, blood tests and rheumatology appointments. I like that the app is made by an indie developer with RA.
