Finally, blood work that makes sense. BloodBuddy turns your lab report into a story you can actually follow. Snap a photo, Bobby reads it for you — and you instantly see what's in range, what's worth a second look, and what "TSH" or "ferritin" even mean. No diagnoses. No panic. No medical jargon. Just your numbers, clearly explained — by a buddy who walks you through it. WHAT YOU CAN DO WITH BLOODBUDDY • Scan your report — photo or PDF from your GP, lab, or routine check-up. Bobby detects your values automatically and slots them into the right markers. • Understand every marker — 115+ blood values in the wiki, written in plain English. What does it measure? What does too high or too low actually mean? What can you do about it? • See your history — every test in one timeline. Spot trends without building spreadsheets. • Real reference ranges — sex- and age-specific. Plus optimal ranges, not just "still borderline okay". • Bobby explains — flagged values come with context. Possible causes, nutrition, lifestyle, supplements — no finger-wagging. WHY BLOODBUDDY → Privacy first. Your values belong to you. Encrypted sync, never sold, never shared. → Offline-first. Once it's in, it's always with you. No signal at the doctor's office? Doesn't matter. → Built from real life. If you do multiple blood tests a year, you know the PDF mess. BloodBuddy is the fix we wanted ourselves. → Bobby talks like a friend who happens to know this stuff. Not like a chatbot. Not like a drug insert. FREE TO USE Manual entry, the full wiki, and your test history — all free, forever. With BloodBuddy Pro you also get: • Lab report scan (OCR) — snap a photo, get the values • Unlimited tests in your history • Multi-year trend analysis • PDF export of your data Subscriptions: • BloodBuddy Pro Monthly • BloodBuddy Pro Yearly (~30% off) Subscriptions auto-renew until cancelled at least 24 hours before the end of the current period.
