Symptom tracker
An endometriosis symptom tracker that forecasts tomorrow, and tells you how sure it is.
HerPattern is a daily endometriosis pain and symptom diary with a research-grade twist: after a couple of weeks of check-ins it estimates the likely burden of your next day, always with an explicit uncertainty range, and turns your history into a report you can print for an appointment.

What the tracker does
A daily check-in that takes under a minute
Track the symptoms that matter to you (pelvic pain, cramping, bleeding, fatigue, bloating, nausea, mood, sleep) on simple 0 to 10 sliders, plus an optional free-text note. You choose which symptoms appear, so the diary stays yours rather than a fixed template.
Voice logging with confirmation
On a hard pain day, speak instead of tapping. A short voice note is transcribed and turned into suggested symptom values, and nothing is saved until you review and confirm every value on screen.
A next-day forecast that shows its uncertainty
Once enough history has accumulated, you see the probability of a low, moderate or high burden day tomorrow, an 80% plausible range around the estimate, and a plain-language confidence label. When there isn't enough recent data, HerPattern says so instead of guessing.

How a week of tracking usually goes
Days 1 to 3
You pick the symptoms you care about and log them each evening. The chart starts to fill in; no forecast yet.
Days 4 to 13
Personalization progress climbs as your own baseline separates from the population baseline. Patterns between symptoms start to surface.
Day 14 onward
The next-day forecast appears with its 80% range and confidence label, and each forecast is later scored against what actually happened.
Questions people ask before starting
- What can I track in the diary?
- Pelvic and abdominal pain, cramping, bleeding and spotting, fatigue, bloating, nausea, bowel and bladder discomfort, sleep quality, mood, and any custom symptom you add. Each day is scored on a 0 to 10 scale and combined into an overall daily burden score.
- How long before a forecast appears?
- The forecast unlocks after roughly two weeks of reasonably regular check-ins. Before that, HerPattern shows your personalization progress rather than a number, because a forecast built on a handful of days would be misleading.
- What does the uncertainty range mean?
- Alongside each estimate you see an 80% range: the band the next day's burden is expected to fall within four times out of five. A wide band means the pattern is still noisy or data is missing; a narrow one means recent days have been consistent.
- Can I take the tracker to a medical appointment?
- Yes. The printable report summarizes recent symptom frequency, burden trend and forecast history on one page so a consultation can start from data rather than recall. It is a record of what you logged, not a diagnosis and not a treatment recommendation.
- Is my symptom data private?
- Your records are visible only to you. Research use is opt-in and consent-scoped, and you can export everything or delete your account and its data at any time from the privacy settings.
A research prototype, not medical care
HerPattern records what you log and estimates patterns in it. It does not diagnose endometriosis, detect clinical flares or recommend treatment, and it is not a substitute for care from a clinician. Read the methodology and the medical disclaimer.
