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.

None Mild Moderate Severe

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.

Example — Top triggers after 30 days
Red wine
82%
Sun exposure
68%
High UV days
54%
Spicy food
38%

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:

RosaceaTrack — Skin diary report Apr 1 – Apr 30, 2026

💡 Pattern found — 4 of the last 5 flare days followed red wine within 6 hours. Confidence: high (12 matching check-ins).
