Smarter with Apple Intelligence, private by design
On supported iPhones, Apple Intelligence makes photo and voice logging, menu and label scans, meal analysis and your weekly reviews smarter. It runs on your iPhone.
Get Heart Tracker free
Heart Tracker uses Apple Intelligence, Apple's own AI, and no third-party AI service. On iPhones that support it, Apple's model runs on your iPhone to understand meal photos and descriptions, read menus and labels, analyse meals and write your weekly notes. Larger requests can use Apple's Private Cloud Compute, but only if you allow it. Every feature has a standard version, so the app works fully without Apple Intelligence.

Your health data and AI
- No third-party AI. Heart Tracker doesn't send your meals, results or photos to ChatGPT, Gemini, Claude or any other AI company.
- On your iPhone by default. Apple's on-device model does the work, so data doesn't leave your phone.
- Private Cloud Compute is off unless you allow it. On iOS 27, some larger requests (a meal photo, a menu, a week plan) can run on Apple's Private Cloud Compute. The first time a feature would use it, Heart Tracker asks: Allow or Keep on iPhone.
- Your most personal data stays on the device. Features that include your weight, activity or test results never prompt for Private Cloud Compute, and stay on the iPhone unless you've already allowed it.
- You're in control. Settings > Apple Intelligence lets you turn Private Cloud Compute, or Apple Intelligence itself, off for the app.
Health insights on your test results are calculated on your device from published guidelines, not by AI. Read the full privacy policy.
Ask a question about cholesterol
The Articles section now has a question box. Ask "Is coconut oil bad for cholesterol?" or "How much fibre do I need?" and Heart Tracker answers from its own articles, with a link to each source. It won't answer personal medical questions. Those it points to your doctor.
Siri and Shortcuts
Ask Siri what's on today's heart menu, check your weekly heart score, tick a food group in your daily check-in or complete today's LDL Reset task. These work through Siri and the Shortcuts app on every supported iPhone.

No. Heart Tracker is free, and the Apple Intelligence features are included.
