Seizure alert and log · iPhone, Android, watch

If it happens tonight, someone will know.

It watches for the shaking. Thirty seconds to cancel. Then your people are called.

In development. Not in the app stores yet. See what it looks for

possible seizure, held 15 s clonic phase

0:27 · 4.6 Hz

1:06 · 2.2 Hz

Same seizure, forty seconds apart, one scale. The rhythm falls away. That is the signature.
What it looks for

A rhythm that slows down.

Plenty of things shake at that rate. Almost none slow down while they do it.

  • Running

    3.0 Hz, holding

    Thrown out

  • Brushing your teeth

    5.1 Hz, holding

    Thrown out

  • Clonic phase

    4.6 Hz falling to 2.2

    Held 15 s

It will miss seizures. That is not a bug we intend to close.

  • Tonic-clonicmotion
  • Focalno signature
  • Absenceno signature
  • Aurano signature

In bed, bedding damps the motion. A second path watches the heart rate instead, and needs a watch. Keep your emergency plan.

When it fires

Thirty seconds, then the phones ring.

A false alarm should cost one tap.

  1. Your phone asks first

    One tap and it never happened.

  2. Your circle is paged

    Through silent and Do Not Disturb.

  3. They get where you are

    Live location. The steps you wrote.

  4. You see who is coming

    Names and arrival times.

Two apps, one account

The person, and the people around them.

“Circle” is a tab in the app, not a metaphor.

If you have epilepsy

  • It watches, or you press

    Background motion. Plus SOS, for when you feel it coming.

  • Thirty seconds to say no

    Nothing is sent behind your back.

  • A log you own

    PDF or CSV, built on your phone. Never uploaded.

If you are the one who comes

  • Your phone rings, loudly

    Through silent and Do Not Disturb. Only they can trigger it.

  • Where they are

    Live while the alert is open, then it stops.

  • Their plan, not a web search

    What they wrote in advance, including when to call an ambulance.

Where it actually runs

What each device can and cannot do overnight.

Overnight cover is the reason to install this. So, exactly:

DeviceWhile you are using itScreen off, app closedHeart rate
Android phoneYesYesNo
iPhoneYesNoNo
Apple WatchYesYesYes
Wear OS watchYesYesYes

  • An iPhone alone cannot watch you sleep. iOS lets no app sample motion with the screen off. On Apple hardware the Watch is the only overnight cover, and the app says so.

  • The watch is also the only pulse. The nocturnal path needs a heart rate rising out of rest. Both signals must agree for twenty-five seconds.

What we will not say

There is no accuracy number on this page.

Publishing one is a diagnostic claim, and that is what requires clearance as a medical device. EpiSeiz has none.

Every screen says

EpiSeiz Possible seizure

Movement that looks like one, 4 seconds ago.

Never

EpiSeiz Seizure detected

The sensors saw movement. They cannot see a brain.

Questions

What people ask before they trust it.

Is EpiSeiz a medical device? No. EpiSeiz is not a medical device and is not clinically validated. It does not diagnose, treat or replace medical advice, and it is not a substitute for the emergency plan you already have.
Will it detect every seizure? No, and that is not a bug we intend to close. It looks for the motion signature of a tonic-clonic seizure — a rhythm that slows while it shakes. Focal, absence and aura seizures have no such signature and will not be detected.
What happens when it thinks something is wrong? Your phone asks you first, and one tap means it never happened. If thirty seconds pass, your circle is paged through silent and Do Not Disturb, they are shown your live location and the steps you wrote in advance, and you are shown who is coming and how far away they are.
How does it tell a seizure from ordinary shaking? By whether the rhythm slows. Running holds around 3 Hz and brushing your teeth holds around 5 Hz; a clonic phase falls away, for example from 4.6 Hz to 2.2 Hz over about forty seconds. Things that shake at a steady rate are thrown out.
Does it work while I am asleep? In bed, bedding damps the motion, so a second path watches heart rate instead. That path needs a watch. Keep your emergency plan either way.
Who needs to install it? Both sides. It is two apps on one account: the person with epilepsy carries one, and each caretaker carries the other. Circle is a tab in the app, not a metaphor.
Can I get my log out? Yes. The log is yours and exports as PDF or CSV.
