Hurtl Helping you take control of chronic conditions
Hurtl is built for people living with axial spondyloarthritis, rheumatoid arthritis, psoriatic arthritis, lupus, fibromyalgia and osteoarthritis. Log what matters, see calculated scores and lab trends, and export clinical PDFs for your next appointment.
Available for iPhone
Hurtl is not a medical device and does not provide medical advice, diagnosis, or treatment. Always speak to a qualified healthcare professional before making medical decisions.
Track what's relevant. Own your progress.
Built for rheumatic and related conditions: log what matters, see calculated scores and lab trends, and bring something concrete to the people who care for you. The Condition tab and clinical PDF export are included with Hurtl+.
Visit prep and condition charts
The Condition tab brings quick log, visit prep summaries and charts tailored to each profile you track — so you know how the last weeks looked before clinic.
Scores that update as you log
See BASDAI, RAPID3, DAPSA, FS/PSD or WOMAC estimates from your daily entries — with 7-day trends and severity labels. Estimates from your logs, not official clinical scores.
Track lab results
Store CRP, ESR, anti-dsDNA, complement and other blood test values with history per test — optional trackers you enable when you need them.
Understand symptom trends
Line charts show how pain, fatigue and other signals change over weeks and months — patterns that are easy to miss day to day.
Never miss a medication
Add medication reminders to get notified on schedules and dosage. Adherence feeds into visit prep and PDF reports.
Clinical PDF reports
Build a doctor-ready report with symptom trends, calculated indices, period comparison, flare summary and your own notes — then export and share in one tap.
Conditions we focus on
Rheumatic and related conditions behave very differently day to day. Hurtl sets up the right trackers, scores and charts for each profile — and supports multiple conditions at once.
Axial spondyloarthritis (axSpA)
Track spinal symptoms, fatigue, flares, and related signals. BASDAI updates from your daily logs with visit prep before clinic.
Index tracked: BASDAI
Rheumatoid arthritis (RA)
Log joint symptoms, morning stiffness and flare patterns. RAPID3, joint involvement and CRP/ESR labs on the Condition tab.
Index tracked: RAPID3
Psoriatic arthritis (PsA)
Capture joint, skin and enthesis signals. DAPSA updates from your logs, including CRP when you record lab results.
Index tracked: DAPSA
Lupus (SLE)
Track lupus-specific symptoms and lab results — anti-dsDNA, complement, urine protein, CRP and ESR — with tailored charts.
Index tracked: Symptoms + labs
Fibromyalgia (FM)
Complete FS/PSD check-ins, track brain fog and unrefreshed sleep, and see your score trend over time.
Index tracked: FS/PSD
Osteoarthritis (OA)
WOMAC check-ins for pain, stiffness and function, plus joint stiffness, swelling and affected-joint tracking.
Index tracked: WOMAC
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 inflammatory arthritis data over time, then turns it into a PDF report you can bring to clinic: averages, trends, calculated indices (BASDAI, RAPID3, DAPSA, FS/PSD or WOMAC), lab results, 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 inflammatory arthritis as you go — not in a rush the night before clinic.
-
See patterns between visits
The Condition tab calculates indices from your logs — BASDAI, RAPID3, DAPSA, FS/PSD or WOMAC — with 7-day trends, visit prep summaries and condition-specific charts.
-
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+.
Why I started Hurtl
A note from Tom, founder
I first realised something was wrong in my early 20s. It began with sleepless nights with back pain and then flares of stabbing “hip” pain that made walking impossible. I remember traveling for work and barely being able to put my socks on when I thought enough is enough.
After years of misdiagnosis, I was finally diagnosed with ankylosing spondylitis (now referred to as axial spondyloarthritis) and began the process of regular doctor appointments asking me about my pain scores to calculate BASDAI.
I always found these scores inaccurate, relying on my memory rather than actual data, so initially I started writing a pain diary. This gave me the idea to develop Hurtl — a more accurate, informative way of keeping track of my condition with ways to share this data directly with doctors and family.
My aim is to give people a useful tool to take control back over their condition — whether that is axSpA, RA, PsA, lupus, fibromyalgia, osteoarthritis or something else entirely.
