Hurtl Rheumatoid Arthritis Symptom Tracker
Log RA symptoms as you go, see your RAPID3 estimate update on the Condition tab, and export a clinical PDF for appointments — built from your data, not guesswork.

What to track with rheumatoid arthritis
An RA symptom tracker works best when it matches how your condition actually shows up — not a generic pain diary.
Joint pain and swelling
Record which joints hurt, how severe it feels and whether swelling is present. Patterns by hand, wrist, knee or other joints are easier to review with a log than from memory.
Morning stiffness
Morning stiffness is a hallmark of RA. Log severity and duration — both often matter when your rheumatologist assesses disease activity.
Fatigue
Fatigue is common in rheumatoid arthritis but easy to under-report at appointments. A simple daily entry builds a clearer picture over time.
Flares
Mark harder days and note what was different. Over weeks, flare frequency and recovery time become easier to see than from recall alone.
Medication response
Record doses taken, missed doses and how you felt afterwards. That context makes it easier to judge whether DMARDs, biologics or other treatments are working.
Function and daily tasks
Note how symptoms affect gripping, walking or work. Small changes week to week can signal a flare building or improving control.
Why symptom tracking helps
Rheumatoid arthritis can fluctuate week to week. A consistent log turns scattered days into evidence you can export before your next appointment.
Walk into appointments prepared
Export a PDF that summarises the months since your last visit — so you are not guessing whether joint pain, stiffness or flares were worse in March or May.
Spot symptom changes early
Daily logs turn vague memory into a timeline. You can see when stiffness lengthened, more joints flared or fatigue crept in — before a full flare takes hold.
Understand flare patterns
Flares rarely appear from nowhere. Tracking helps you connect symptoms to triggers, activity or treatment changes so you can respond sooner.
Track medication effectiveness
Starting methotrexate, a biologic or adjusting steroids? Adherence and symptom trends in your report show whether treatment is working over weeks, not just today.
Take the guesswork out of rheumatology appointments
Appointments often hinge on “how have you been since we last met?” — and memory is unreliable. Hurtl collects your rheumatoid arthritis data over time, then turns it into a PDF report you can bring to clinic: averages, trends, RAPID3, lab results where relevant, flare days and medication adherence in one place.
-
Log symptoms and labs in the app
Track pain, stiffness, fatigue, flares, lab results and medication for rheumatoid arthritis as you go — not in a rush the night before clinic.
-
See patterns between visits
Charts and RAPID3 update from your entries so you know how the last weeks actually looked, not how you feel today. Scores in the app are estimates from your daily logs — not official clinical scores.
-
Export a PDF for your appointment
Choose the date range, pick what to include, add notes for your clinician, and share a doctor-ready PDF from Home, Condition, Insights or any tab header.
You choose the date range, sections and clinician notes. Your log stays on your device until you export — the report is for preparation, not a clinical diagnosis. Clinical PDF export is included with Hurtl+.
RAPID3 and how Hurtl helps
RAPID3 (Routine Assessment of Patient Index Data 3) combines physical function, pain and a global estimate of how active your arthritis has been. Hurtl calculates a RAPID3 estimate from your daily logs on the Condition tab — with a 7-day trend and severity label. It is an estimate from your entries, not an official clinical score.
The three RAPID3 domains (clinical)
When your rheumatologist calculates RAPID3, they combine three patient-reported areas:
- Physical function Difficulty with daily activities from your function assessment
- Pain Overall pain level you have felt
- Patient global estimate How active your arthritis has felt overall
Your RAPID3 estimate in Hurtl
Hurtl adds pain, daily activities and overall wellbeing from your logs for a running RAPID3 estimate — usually 0 to 30. You see today’s inputs, a 7-day trend and a severity label on the Condition tab.
Scores in Hurtl are estimates from your daily logs — not official clinical scores. Your care team may calculate RAPID3 differently at appointments.

What else Hurtl provides
Joint involvement tracking, CRP/ESR lab results, visit prep for the last 30 days, flare history and clinical PDF exports — so appointments start from what you recorded, not memory.
How Hurtl helps
Hurtl is built for inflammatory arthritis, not a generic wellness app. Collect RA data daily, spot trends in the app, and export a PDF when it is time for clinic.
Condition-specific symptom tracking
Log joint symptoms, stiffness, fatigue and other RA signals from pre-set lists — or create custom trackers for what matters to you.
Flare logging
Mark harder days and note what was different. Trend charts make flare patterns visible over weeks and months.
RAPID3 from your daily logs
Hurtl calculates a RAPID3 estimate from pain, daily activities and overall wellbeing — with a 7-day trend and severity label. An estimate from your logs, not an official clinical score.
Lab results
Store CRP and ESR when you get blood tests — with history per test and optional trackers you enable when needed.
Medication reminders
Set reminders for weekly methotrexate, daily treatments or biologics. Track adherence alongside symptoms to see the full picture.
PDF reports for appointments
Turn months of logs into a shareable export: summary metrics, pain and fatigue charts, flare days and medication adherence — ready before you sit down with your rheumatologist.
Frequently asked questions
What should I track with rheumatoid arthritis?
Most people find joint pain, morning stiffness, fatigue and medication adherence the most useful starting points. Add flare notes and function when you want more detail. You do not need to log everything every day — consistency beats completeness.
What is RAPID3?
RAPID3 (Routine Assessment of Patient Index Data 3) is a simple patient-reported score used in rheumatoid arthritis. It combines three areas you rate yourself: physical function, pain, and a global estimate of how active your arthritis has been. Many clinics use it because it is quick and needs no lab tests.
How is RAPID3 calculated in clinic?
In a rheumatology visit, each of the three RAPID3 components is scored (often 0–10, with physical function from a short questionnaire). Clinicians add them for a total from 0 to 30 (sometimes scaled to 0–100). Lower scores generally mean less disease activity; your rheumatologist will interpret results in context.
Does Hurtl calculate RAPID3?
Yes. Hurtl calculates a RAPID3 estimate from your daily logs — pain, daily activities and overall wellbeing — with a 7-day trend on the Condition tab. It is an estimate from your entries, not an official clinical score. Your rheumatologist may use their own scoring at appointments.
Can tracking help with RA flare management?
Yes. A symptom diary helps you notice when a flare is building, what may have triggered it and how long recovery takes. That makes it easier to adjust activity, contact your rheumatology team early or prepare for appointments with concrete examples.
Can I share symptom history with my doctor?
Yes. Export a PDF report for the period you choose — averages, pain charts, flare summary and medication adherence — and share it at your rheumatology or GP appointment. You control when and what leaves the app.
How does Hurtl help before a rheumatology appointment?
Log symptoms as you go, then generate a report before clinic so you are not reconstructing the last three months from memory. That takes the guesswork out of questions like how often you flared or whether your current treatment is helping.
