Four moments your labs make sense.
Organized by body system, not by lab name.
Heart, Metabolic, Liver, Kidney, Thyroid, Blood, Hormones, Vitamins. Each category card shows your most-recent panel date, biomarker count, and a status trail across recent results.
One value, with the context to read it.
Tap any biomarker. Latest value at the top. A delta from your previous result. A trend chart with the lab's reference range as a soft band. A plain-English explainer of what the marker is, sourced from AHA, Cleveland Clinic, or MedlinePlus.
What else was happening on these dates.
Resting heart rate, weight, and HRV from Apple Health show up across the same date window as your lab. Medication starts and health events you logged appear on a quiet timeline. Two things happening at once — not one causing the other. You draw the connection.
A document your doctor recognizes.
One tap renders a vector-sharp PDF stamped with the Leo icon — cover page, out-of-range summary, per-panel detail tables in a LabCorp-style layout, and a provenance page naming every source the data came from.

Lab Results PDF
Connect the dots, without claiming the dots are connected.
Leo shows your data on a single timeline. The conclusions are yours to draw — and to talk through with your doctor.
We describe where the value sits inside the lab's reference range. We don't call it good, bad, or risky.
The hero biomarker page.
The latest value, the delta from your previous result, the lab's reference range as a soft band, and a calm status pill. Numbers that read instead of stare.
Leo never says “high,” “abnormal,” or “at risk.” The lab decides the reference range; Leo describes where you sit inside it.
Around the same time.
Your resting heart rate from Apple Health, plotted across the same date window as your lab. Your medication starts surface as quiet tick marks on the same axis.
Two things happening at once — not one causing the other. You read the relationship; we won't pretend to.
Two things happening at once, not one causing the other. Sample data shown.
Connect your labs
You'll set this up once in Apple's Health app. Leo picks up the rest.
Before you start: have your patient portal username and password handy (MyChart, MyQuest, LabCorp Patient, Kaiser, Mayo Patient Online Services).
- 1
Open the Health app
It's the white icon with a red heart on your iPhone home screen.
If you can't find it, swipe down on your home screen and search “Health.”
- 2
Tap Browse, then Health Records
Browse is the bottom-right tab. Health Records is its own card on that screen.
If you don't see Health Records, tap your profile picture in the top-right and choose Health Records → Get Started.
Browse → Health Records - 3
Tap “Add Account”
Apple will ask for your location so it can suggest providers near you.
Tap Allow While Using App. Apple uses location only to surface nearby hospitals and labs — it isn't shared with Leo.
Health Records → Add Account - 4
Search for your provider
Search by the name of the parent health system, lab, or patient portal — not your individual clinic.
Hospital systems: “Mayo Clinic,” “Cleveland Clinic,” “Kaiser Permanente,” “Sutter Health,” “Johns Hopkins.” Labs: “Quest Diagnostics,” “LabCorp.” Local clinic? Try the parent EHR — “Epic MyChart,” “Athenahealth,” or “NextGen.”
- 5
Sign in with your patient portal
Use the same email and password you use for your provider's website.
You may need to verify a code by text. When iOS asks to share records with the Health app, tap Allow.
- 6
Wait one to two minutes
Apple downloads your last few years of lab results, medications, immunizations, allergies, and visit summaries.
First-time syncs can take longer — sometimes up to 24 hours. You don't need to keep the app open.
- 7
Open Leo and tap Labs
The first time you open Leo's Lab dashboard after connecting, iOS will ask to share Clinical Records with Leo.
Tap Allow. Your results appear organized by category (Heart, Metabolic, Liver, Kidney, Thyroid, Blood, Hormones, Vitamins) automatically.
Leo → Labs
If you get stuck
My provider isn't showing up.
I see “Unable to Connect.”
My records aren't showing up in Leo.
My most recent results aren't there yet.
The line we won't cross.
Leo doesn't interpret your data. That's a feature, not a limitation — and it's why your clinician will trust what we hand them.
We describe, we don't interpret.
Reference ranges come straight from the lab. Leo reads where your value sits inside that range and calls it descriptive — never severity, never a diagnosis.
Plain English, sourced.
Every biomarker explainer is sourced verbatim from the American Heart Association, Cleveland Clinic, or MedlinePlus. We cite the source. We don't generate copy from your values.
Leo isn't your doctor.
We're a wellness app, not a regulated medical device. We don't tell you what your numbers mean for your body — we organize them so the conversation with your clinician is easier.
A document your doctor recognizes.
Tap Share on the Labs page. Leo renders a vector-sharp PDF stamped with the Leo icon — cover page, out-of-range summary, per-panel detail tables, and a provenance page that names every source the data came from.
- LabCorp-style flag column (H / L / H! / L!), in warm amber, never clinical red
- Reference ranges shown verbatim from the source lab
- Provenance page lists every source the data came from
- FDA general-wellness disclaimer printed on every page
Your lab results
A summary you can hand to your clinician.
Sample preview — values shown are illustrative.
Your labs, your iPhone.
Leo is opinionated about what we don't do.
Stays on your iPhone.
Leo reads from Apple Health Records on-device. We don't run a portal scraper or a backend that holds your raw lab feed.
Never sold.
Your health data isn't sold, brokered, or shared with advertisers. Leo's business model is paid subscriptions, not your data.
Wellness, not a device.
Leo is a wellness app. Reference ranges come from your lab. We don't interpret your results clinically — that's your doctor's job.
Common questions
Can I track lab results in Apple Health?
Does LabCorp connect to Apple Health?
Does Quest connect to Apple Health?
Is my data private in Apple Health Records?
How do I add my hospital to Apple Health?
What's the difference between Apple Health and Apple Health Records?
Leo is a wellness app. Leo is not a medical device. Reference ranges shown in the app come from the laboratory that ran your test, and Leo does not interpret your results clinically — please review them with a licensed clinician.
Always talk to your doctor about your results.
