Features

What Herald does, and what it doesn't

Herald keeps a record of your seizures, auras, medications and days, describes what you logged, and lets the people you choose know when you start a heads-up. It describes, never diagnoses, and it isn't an emergency service.

Log in a moment

A seizure, an aura or a note in one tap, from wherever you are.

  • Today, your Apple Watch, the Action button, Control Center, the Lock Screen or Siri
  • Details when you're ready: how long, what you noticed, rescue medication, how you were after
  • A video someone took, kept on your iPhone only

A calm daily record

For the steady months too, when there's little to log.

  • A three-tap check-in for sleep, stress and energy, and your mood if you like
  • Your medications from Apple Health or Herald's own list, with reminders and a count of what's left
  • Your sleep from Apple Health, beside how you felt

A heads-up you start yourself

When you feel a seizure may be coming, let the people you trust know.

  • From your iPhone or Apple Watch, Siri or the Action button, with a few seconds to cancel
  • They see it at once, with what helps, your seizure action plan and, if you choose, where you are
  • A timer from when you started, and the moment your plan says to call for help
  • Practice it any time: a practice tells no one and saves nothing

Herald never detects seizures and never calls anyone for you. For an emergency, call your local emergency number.

Herald's heads-up on an Apple Watch

Your whole history, in one place

Every seizure, check-in and dose, each with its day, and the time where you were when it happened.

Herald Plus

Patterns, in plain words

The days your seizures fell on, and how you'd slept and felt before them. They're observations, not predictions.

Where Apple Intelligence is on, it can word a pattern in everyday language, on your device only, marked as its words. Nothing leaves your device.
