Patients Arrive with Up to 60 Days of Data. You Skip the Reconstruction.
Flarity is a patient-facing iPhone app for people with IBD. Between visits, it tracks Apple Watch data and symptom scores. Before their appointment, patients generate a PDF summary.
You get objective trends and validated indices instead of "I think it started a few weeks ago."
The app does not diagnose or treat. It organizes patient-reported data so you can start the conversation informed.
How It Works in Practice
- Patient downloads the app on their own (or you mention it)
- With Apple Watch: The app monitors passively. If signals deviate from baseline (HRV drop, elevated resting HR, sleep disruption), it prompts a 30-second symptom check-in. No daily logging.
- Without Apple Watch: Optional scheduled check-ins (morning/evening). Still useful, just without the early warning layer.
- Before their next visit, they tap "Generate Report" (30 seconds)
- They bring a PDF via email, AirDrop, printout, or show it on their phone
What This Is Not
- Not a diagnostic tool. It does not tell patients they are flaring.
- Not FDA-cleared. It is a wellness app, not a medical device.
- Not a monitoring service. You do not check anything between visits.
- Not a messaging system. Patients cannot contact you through it.
- Not a replacement for labs. No calprotectin, no CRP, no bloodwork.
It is structured patient history. That is it.
What's in the Report
Executive Summary
- Current status (remission, recovering, active flare)
- Key action items flagged upfront
- Assessment breakdown (wearable vs. symptom components)
Wearable Trends
If patient has Apple Watch
- HRV, resting heart rate, sleep, steps
- 7-day average vs. their personal baseline
- Change direction and magnitude
Flare History with Pre-Flare Analysis
- When flares occurred, duration, peak severity
- Which wearable signals deviated before symptoms appeared
- Confidence score based on data completeness
Clinical Scores
- HBI (Crohn's) or SCCAI (UC) over time
- Trend direction
Medication Adherence
- Percentage logged vs. prescribed
- Historical medications (discontinued biologics, etc.)
Auto-Generated Questions for the GI
- Based on actual data patterns, not generic prompts
- Examples: "My flare happened while on Skyrizi. Should we check trough levels?" / "My average sleep is 5.7 hours. Is poor sleep making my IBD worse?"
Reports are typically 1-3 pages depending on activity. See sample report →
Common Questions
Does this create work for me between visits?
No. The app does not send you anything. Patients bring a report when they come in. You are not responsible for monitoring, responding, or reviewing anything outside of scheduled appointments.
Will patients message me through this?
No. There is no messaging. If your patients use Medeo or another platform to reach you, that does not change.
How accurate is the "risk score"?
It is a trend indicator, not a diagnostic. Wearable data alone caps at 3.5/7. Full scoring requires patient-reported symptoms, which helps filter out false positives from stress, poor sleep, or unrelated illness.
The app does not tell patients "you are having a flare." It shows them patterns. You decide what matters.
What if the patient says they are flaring but the Watch data looks fine?
The patient's report wins. Wearable signals are supplementary. If someone says they are in a severe flare, the score reflects that immediately. The app does not second-guess your patients.
Will this increase patient anxiety?
Most find the opposite. Having data reduces the "am I imagining this?" uncertainty. The app uses calm language. During active flares, it shifts to supportive guidance rather than showing them numbers.
What does it cost?
Free to you. Patients pay $14.99/month or $149/year after a 21-day trial.
The Research
You have likely seen the 2025 Mount Sinai study in Gastroenterology: 300+ IBD patients, wearable signals correlating with flare patterns. Flarity is a conservative implementation of that work. It is not making predictions; it is showing trends for your interpretation.
Privacy & Boundaries
- All data stays on the patient's phone unless they share it
- No alerts to you, ever
- The app tells patients it does not replace your advice
- You engage as much or as little as you want
If You Want to Mention It to Patients
Patients download at getflarity.com.
You could say something like:
"There is an app called Flarity that tracks your symptoms and Watch data. If you try it, you can bring a report to your next visit. Might help us get on the same page faster."
Or just do not mention it. Some patients find it on their own.
