On iPad, the same diary opens into a spacious view for readings, meals, treatment, labs, appointments, and records.

Every part earns its place.

Three connected stories show how focused tracking can become a useful record.

Track patterns, not isolated numbers.

Blood pressure, glucose, and weight each get a focused home, with recent values, longer trends, personal ranges, notes, and the clinical context needed to understand what changed.

  • Blood pressure zones and meal-aware glucose ranges
  • Weight Trend, goals, milestones, and forecasts
  • Two-way Apple Health sync at no cost

Recent readings, target ranges, and longer trends stay together.

Add the daily context around those readings.

Meals, medications, and activity stay useful on their own while adding the everyday context that a measurement cannot provide by itself.

  • Type, search, scan, photograph, or speak a meal
  • See today’s doses without rewriting yesterday’s regimen
  • Bring steps and workouts in through Apple Health

AI meal estimates remain editable and should always be reviewed before saving.

The Activity screen with 5,400 steps, 320 active calories, one 35-minute workout, Activity rings, and step-goal progress
Nutrition targets and logged movement make the day’s progress visible at a glance.

Keep records useful—and share only what you choose.

Turn lab reports into confirmed results, protect documents, prepare a focused snapshot, or share supported records read-only with a caregiver.

  • Review, redact, and approve before AI lab extraction
  • Create plain-text, printable, and PDF reports
  • Control and revoke end-to-end encrypted Shared Access

Your health is personal.
The architecture should be, too.

Your diary begins on your device without an account for core tracking. Optional Encrypted Backup & Sync seals supported records and files before upload, and Shared Access uses a separate end-to-end encrypted channel for the supported records you choose.

Do I have to use every part of MED Diary?

No. Start with blood pressure, glucose, weight, or any combination you prefer. Reorder the vital screens, Home cards, and Quick Access destinations, then keep Meals, Medications, Labs, Appointments, Activity, or documents hidden until they become useful. Turning a module off does not delete its existing history.

Where is my health data stored?

Your diary begins on your device and stays there unless you choose otherwise. Optional Backup & Sync, part of Premium, encrypts supported records and files on device before our server stores them, keeping the diary current across your devices. See how the sealed backup works. Live AI receives only the lab PDF or meal content you deliberately submit through the MED Diary server. Shared Access relays separately encrypted record envelopes plus the limited metadata needed to operate the service. See the Privacy Policy for the full data flow.

How does caregiver sharing work?

You choose supported vitals, current medications plus dose events and adherence, and individual lab results. Your device encrypts those records with a key carried in the full invite; the relay never receives that key. MED Diary Follow presents a read-only view to the invited caregiver. See the security details.

What does MED Diary cost?

MED Diary is free to download and includes unlimited vital and meal history, up to three current medications, up to three upcoming appointments, Apple Health, customizable Home cards, plain-text sharing, and raw export; the free diary lives entirely on your device.

Read the introduction transcript

Meet Alex. MED Diary keeps the pieces of his health in one place, then helps them make sense together.

Home gives Alex a quick read on vitals, meals, activity, medications, records, and appointments. Its controls speed up common entries. Customize in the bottom toolbar lets him add, remove, and reorder readings, screens, and actions across Home and Quick Access.

History brings readings and meals into one timeline, with trends, target ranges, notes, and time in range. Opening a result like LDL cholesterol adds its lab range, change from the previous test, and longer-term direction.

Meals can be typed, searched, scanned, spoken, or photographed. After reviewing the estimate, Alex sees calories and nutrients beside glucose, weight, and movement. Activity keeps steps, workouts, and goals beside the rest of the day, adding context without treating one day as the whole story.

Medications shows what is due, taken, skipped, or missed, and preserves earlier regimens after a prescription changes, keeping today’s schedule and treatment history clear.

Lab reports can be photographed or imported as PDFs. Alex reviews privacy, redacts on his phone, approves what leaves it, and verifies each result. Test Results then organizes the values by body system or common panel, with ranges and flags.

Appointments, insurance cards, prescriptions, documents, and printable reports keep the practical details together when Alex is preparing for a visit.

Share in the bottom toolbar offers a one-time copy of vitals, medications, or test results for a doctor, or Trusted Sharing for ongoing support. Alex controls what a family member, caregiver, or coach sees, perhaps meals and weight for a coach, and can stop access anytime.

Start with what matters. MED Diary keeps the detail organized, the context connected, and control of your health information in your hands.
