What's New in JointSignal

1.3

September 26, 2026

• Medicines taken on several days a week: multiple days of the week can now be selected. • Dosing notes: write down how to take a medicine, like a dose that builds up over several weeks. They appear on Today, in Treatment and on your report. • Past appointments now open a record of the questions you asked, the side effects you had, the medicines you were on and your blood results at the time. You can add answers to questions afterwards. • Doses and blood results print on your report exactly as you entered them.

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.
