Bring the receipts. Get taken seriously.
A symptom diary for endometriosis and chronic pelvic pain. Log what your body does, record what happens at every appointment, and walk into the consulting room with evidence instead of memory.
// Waitlist
One email when Yellow is ready. No spam.
// Features
01 · Daily log
Your usual suspects, rated on a scale you can tap without thinking. Voice notes and photos when words won't do it.
02 · Your patterns
Flare timeline, calendar, cycle correlation, and the rhythms you'd never spot from memory — which days hit hardest, and when.
03 · Did it help?
Prescriptions, remedies and surgery, all measured the same way. Before and after, in a number, so you know what's actually working.
04 · Paper trail
Log every appointment and how it went — referred, prescribed, dismissed. A record of the road you've been made to walk.
05 · What it cost
Missed work, cancelled plans, days you couldn't get out of bed. The impact that doesn't show up in a blood test.
06 · The receipts
A clinical summary of the last 90 days — frequency, severity, cycle correlation, care timeline. Export it and bring it with you.
// How it works
1
Symptoms, severity, flow, treatments, appointments. Photos and voice notes for the things that are hard to describe.
2
Yellow does the quiet listening. Over weeks it turns scattered bad days into patterns you can point at.
3
Export a one-page summary before your appointment. Walk in with a record, not a half-remembered account of the last six months.
// Privacy
No account. No cloud. No analytics. No third-party SDKs of any kind. Everything you log — including photos, video and voice notes — is stored only in Yellow's private storage on your device, and can be locked behind Face ID. Nothing is uploaded, so there is nothing for anyone to sell, leak, or hand over. Delete the app and it's gone.
Yellow is a symptom diary. It records what you enter and shows it back to you — it doesn't diagnose anything, and it doesn't give medical advice. It's built to make the conversation with your doctor a better one, not to replace it.
