Headaches now syncs with iCloud. Your attacks, symptoms and notes stay up to date across your iPhone and iPad automatically, and they're backed up. Your existing history moves over on first launch, nothing to set up.

You can also add an Attack Tracking button to Control Center to start or end tracking without opening the app.

Siri and Shortcuts are much more reliable. They now work instantly from a cold start and always read your real history. Live Activities no longer restart or linger. Plus fixes for duplicate attacks, lost edits while filtering, and time zones on attacks imported from Apple Health.
