Frequently asked questions
How the scoring works, what the doctor report looks like, and what early users have found.
How is the flare score calculated?
The flare score is a number you set each day — from 0 (no flare) to 10 (severe). It's your subjective read of how your skin felt that day: redness, burning, swelling, pustules. No algorithm fills it in.
The app uses your daily scores to compute weekly averages and trend lines in the Insights screen. A "flare day" is defined as any day where your score exceeds your personal 30-day average by more than 1.5 points — this baseline adapts as your data grows.
How are trigger correlations calculated?
Each time you log a trigger (e.g. red wine, sun exposure), the app records it alongside your score for that day. Over time it calculates a correlation percentage: the proportion of check-ins where that trigger appeared and your score that day or the next was above your personal flare threshold.
Rose bars ≥ 60% — strong correlation. Amber bars 30–59% — moderate. Triggers with fewer than 5 data points are hidden until there's enough evidence.
Correlation is not causation — a high percentage means the trigger and flares often co-occur, not that one causes the other. Use these numbers as a starting point for conversations with your dermatologist, not a diagnosis.
What's in the doctor PDF report?
The one-tap export generates a structured PDF designed to be read in a 5-minute appointment. It includes four labeled sections:
Date · Score · Symptoms · Triggers logged · Free-text notes — one row per day, chronological.
The report is generated on-device and is never stored or shared — you download it and decide what to show your doctor.
