Know your flare risk
before it happens
Guiding Crohn's and UC patients toward better days. No daily surveys. We only ask when your body shows changes.

IBD Patients Deserve Better Than Being Blindsided
Over 3.5 million people in North America live with IBD: Crohn's, Colitis, or Indeterminate. Every flare means cancelled plans, missed work, emergency calls to your GI. What if you could see it coming?
Two Layers. One Complete Picture.
Wearables alone can't assess pain or urgency. Symptoms alone rely on imperfect memory. Combined assessment, like your GI uses, gives you the full picture.
Watch monitors passively
HRV, heart rate, sleep. Collected automatically so you don't have to log daily.
AI detects changes
When signals deviate from your baseline, we notice before you feel it
Smart prompt appears
"Your body is showing some stress. Quick 30-second check?"
30-second check-in
Pain, bowel frequency, energy. If risk is low, that's all we need.
Flare Mode activates
If risk is high, we guide you through full HBI/SCCAI scoring + one-tap report for your GI
Wearable Layer
HRV, heart rate, sleep, temperature, activity, SpO2. Collected automatically, analyzed against your personal baseline.
Symptom Layer
Only asked when your body shows stress signals. 30 seconds, max 3 times per week. No survey fatigue, ever.
Combined Score
Wearables plus symptoms equals the same methodology your GI uses. Risk scores from 0-7 with breakdown of what's driving it.
No Apple Watch? No Problem.
iPhone-only mode uses symptom patterns with scheduled check-ins. Upgrade anytime without losing data.

Common Questions
Everything you need to know about Flarity
No! Flarity works great with just your iPhone. The Apple Watch adds passive health monitoring for more accurate predictions, but you can still track symptoms and get insights without one.
Flarity uses a hybrid detection system that combines wearable biometrics (heart rate variability, resting heart rate, sleep quality) with your symptom check-ins. Our AI analyzes patterns to give you 3-7 days advance warning before symptoms typically appear.
Absolutely. All processing happens on your device. Your health data never leaves your phone and is never sent to our servers. We use Apple's HealthKit with the highest privacy standards.
We use validated clinical indices including the Harvey-Bradshaw Index (HBI) for Crohn's Disease and the Simple Clinical Colitis Activity Index (SCCAI) for Ulcerative Colitis. The same tools your gastroenterologist uses.
Yes! Generate detailed PDF reports with your symptom history, risk trends, and clinical scores. Share them directly with your gastroenterologist to have more productive appointments.
With an Apple Watch, your wearable data does the heavy lifting. We only prompt you when something looks off. Quick check-ins take 30 seconds. If your check-in shows elevated risk, the app enters Flare Mode and guides you through full HBI/SCCAI scoring with a one-tap report for your doctor.
No. Flarity is a health tracking and awareness tool that helps you understand patterns in your condition. Always consult your healthcare provider for medical advice and treatment decisions.
Flarity supports Crohn's Disease, Ulcerative Colitis, and Indeterminate IBD (IBD-U). Each has appropriate clinical scoring. You can configure the app based on your specific diagnosis.
