I built a rosacea tracker because I couldn't figure out my own triggers

I've had rosacea for years. Every flare left me guessing - was it the wine last night, the heat yesterday, the stress from the week before? I was trying to reverse-engineer patterns in my head with no data.
I tried existing apps. Most are just glorified diary forms - you log, nothing happens.
None of them pulled in weather automatically, none did any pattern detection, and none produced anything useful to bring to a dermatologist appointment.

So I built RosaceaTrack.

What it does:
- Daily check-in: flare score, symptoms, triggers (food, skincare, environment, gut health), optional photos
- Automatic weather data (UV, humidity, temperature, wind) pulled for every entry without manual input
- Pattern detection: after a few weeks it shows which triggers correlate with your worst days
- One-tap PDF report structured for a dermatologist appointment

The check-in flow is aligned with the National Rosacea Society's 2026 clinical diary - the same format dermatologists recommend.

Where I am now:
Waitlist is live at rosaceatrack.app, with a 60-day free trial, no credit card required.

Still pre-launch — working on getting first real users before building more features.
