Apple Health is the best home for wearables and vitals. Libby is where your blood work lives — import a PDF or photo from any lab and it joins one timeline with your Quest, LabCorp, and doctor's labs, ready for AI or a clinician.
Libby is a companion to Apple Health, not a replacement — keep Apple Health for your wearables.
Apple Health is genuinely great software. The question its own users ask most is where should my blood test results actually live? — and that's the gap a record built for lab data fills.
The best home for the data your iPhone and Apple Watch collect — steps, heart rate, HRV, sleep, workouts — captured continuously and charted cleanly. It can also show records from hospital systems you've connected.
Imports a lab PDF — or a photo of the report — from any lab, reconciles the units, and files each marker onto one lifelong timeline you own and can export. So scattered results become a history you can track and hand to AI or a clinician.
Read this as “these do different things,” not “one wins.” Apple Health is unbeatable for wearables; a record built for labs is where your blood work belongs.
