I built a free tool to track blood panels over time — looking for beta testers
BloodId — upload your blood test PDFs or phone photos, get every biomarker extracted into a searchable, char-table history. Free to try, no credit card, I'm the builder and I'd like your honest feedback.
Why I built it
I do full panels every 6 months and the "dashboard" was a folder of PDFs. Spreadsheets break the moment units differ (mmol/L vs mg/dL), reference ranges vary between labs, or you move countries. Existing apps either lock you into their testing service or run weak extraction pipelines.
What it does
Upload PDF / JPG / PNG / WEBP of any blood panel — digital PDFs, scanned PDFs, or phone photos
AI-powered extraction pulls biomarker names, values, units, and reference ranges directly from the document
Every extracted value has a confidence score; anything uncertain gets flagged for your review before it's saved — nothing is stored silently
Works across labs and countries — tested on US and Serbian lab reports so far
Multi-profile: track your own panels + family members on one account
Per-biomarker reference ranges: same-lab results use that lab's range; multi-lab comparisons fall back to a clinical-standard range
You can override any reference range with your own (e.g., Attia's ApoB <60, fasting insulin <5, etc.)
AI chat on your own data — ask "why is my ferritin trending down?"
What it doesn't do (yet)
No order-a-panel service. It's a tracker, not a lab
Payment system is still being wired up — there's a free allotment on signup that covers most exploratory use
Web-only for now (mobile browser works fine)
Privacy
All data is encrypted at rest on secure US-based infrastructure. Full privacy policy linked in-app.
The ask
Honest feedback on:
Does the upload → review → chart flow make sense?
Are the default reference ranges useful, or too US-centric?
What's missing that you'd actually use?

I'll be in the thread to answer questions and fix anything painful fast.
