Eight years is the average wait for an endometriosis diagnosis. Yellow turns your daily symptoms into a GP-ready report, so you walk in with evidence, not memory.
They told you it's just bad periods. Everyone gets cramps. Have you tried the pill? Your scan looked normal.
Endometriosis takes eight years to diagnose on average. Not because it's rare, 1 in 10 women have it, but because symptoms get waved away, visit after visit. The wait ends when the story becomes a record.
Yellow is a symptom diary with one job: turning your days into evidence.
THE 20-SECOND LOG
Tap through symptoms, severity, bleeding and what the day cost you: missed work, cancelled plans, bed-bound. On flare days when typing is too much, say it out loud instead and Yellow files it.
BRING RECEIPTS
One tap builds a GP-ready PDF. Flare intensity across 90 days. How often each symptom hits and how hard. Cycle correlation. What you tried and whether it helped. Every appointment where you were referred, prescribed or dismissed. The whole story, in the language clinics take seriously.
THE EVIDENCE VAULT
Photos of endo belly and swelling. Video of the days words don't cover. Voice notes recorded at home, on the day, in your own voice, transcribed automatically. Everything dated, tagged to a symptom and locked behind Face ID. Bring in old photos from your library and Yellow files them under the day they were actually taken.
PATTERNS THEY CAN'T ARGUE WITH
A calendar of your months, drawn automatically as you log. "Worse before my period" stops being a feeling and becomes a number.
DID IT ACTUALLY HELP?
Prescriptions, painkillers, surgery, cutting out gluten, the heat pad. Yellow measures your severity before and after each one and tells you straight, even when the answer is "barely."
THE PAPER TRAIL
Every appointment and what came of it. Referred. Prescribed. Dismissed. Told it's normal. Dated, and on the record.
YOURS. ONLY YOURS.
No account. No cloud. No ads. Your record lives on your phone and nothing leaves it unless you build a report and hand it over yourself. Your symptoms aren't a business model.
Daily logging is free for as long as you like. Yellow Pro unlocks your full history, the evidence vault and the GP report, as a subscription or a one-off lifetime purchase.
Yellow is a diary, not a doctor. It doesn't diagnose or treat anything. It makes sure that when you finally sit in front of the right person, you're not relying on memory.
For every symptom they said was normal.
