Health diary · Symptom tracker · Daily plan
Write how your body feels in your own words. Health Diary organizes the details, connects the patterns, and combines your diary with Apple Health to suggest a few useful actions for movement, meals, sleep, and recovery.
A health app that leads somewhere
Your health story is spread across sleep, movement, symptoms, mood, meals, and memory. A dashboard can display those signals without explaining what they mean together.
Health Diary gives them a simple structure: capture what happened, understand the pattern, and choose a realistic action for today.
How it works
No complicated forms. No intimidating medical dashboard. Start with what you already know.
Describe discomfort, energy, sleep, mood, food, or recovery in the words you would normally use.
Health Diary organizes timing, severity, body regions, triggers, relievers, and other useful context.
Review timelines, frequency, severity, common triggers, and trends across the date range you choose.
Use your goals, diary, and Apple Health signals to create a short, achievable Today plan.
Personalized Today Plan
Today Plan brings together your goals, questionnaire, recent diary entries, and optional Apple Health data. Instead of a generic score, it gives you a small set of concrete ideas for movement, nutrition, sleep, recovery, and reflection.
Made for the Apple ecosystem
Health Diary uses Apple frameworks to reduce friction between noticing a signal and doing something useful with it.
On compatible devices, Apple’s on-device language model helps turn free-form health notes into structured entries and creates short, editable diary drafts from approved daily context.

Health diary and symptom tracker
When symptoms repeat, memory compresses the details. Health Diary keeps the timeline clear without demanding a long checklist every day.
Write naturally, then review a consistent record of severity, timing, duration, and body region.
See frequency, common triggers, body areas, severity distribution, and weather context.
Filter a clean health timeline and review the details you do not want to forget.
Inside Health Diary
Who Health Diary is for
Keep a consistent record when headaches, fatigue, digestive discomfort, pain, or sleep issues return.
Turn steps, sleep, activity, and workout data into context for a plan—not another score.
Walk in with a timeline of what happened, when it happened, and what changed.
Use a small Today plan to make movement, food, rest, and reflection feel manageable.
Privacy and control
Health Diary asks before reading Apple Health or photo-library context. Foundation Models features run on device when Apple Intelligence is available. Some advanced analysis features use a server service; only the context needed for the requested feature is sent.
The app is for journaling and personal awareness. It does not diagnose conditions or replace a qualified healthcare professional.
