Open Seizure Detector is an experimental epileptic (tonic-clonic) seizure detector / alert system that utilises a smart-watch to detect shaking, and raises an alarm for a carer. If the wearer of the watch shakes for 15-20 seconds, the device will produce a warning. If the shaking continues for another 10 seconds it raises an alarm.

The phone app communicates with the smart-watch and can raise alarms in one of two ways:
- If it is being used in the home, other devices can connect to it via WiFi to receive alarm notifications.
- If it is being used outside it can be configured to send SMS text message notifications that include the location of the user, as wifi notifications are not possible away from home

The system includes self-checking to make sure it is functioning correctly, and will beep to warn the user of faults to help provide reassurance that it is working.

You need a Pebble Smart Watch or a Pebble Time Smart Watch that is connected to your Android device for OpenSeizureDetector to work.. Note that manufacture of Pebble watches has been discontinued, but this app will continue to work despite this (and pebble watches are still available at the moment).
Note that there is a version currently being tested that provides support for a high-end Garmin watch as an alternative - this will be released in a few weeks.

It does not use any external web services to detect seizures or raise alarms, so is not dependent on an internet connection to work, and no subscriptions to commercial services are needed.

Please see the Installation Instructions for help with setting up this app.

I recommend subscribing to email updates to the OpenSeizureDetector web site or Facebook Page if you use the app so I can contact users if I find an issue you should know about.

Note that this app is experimental so may not be reliable at the moment, but comments would be appreciated. That said, I have had some positive feedback from users saying that it has detected tonic-clonic seizures reliably, but it has not been subjected to 'proper' qualification testing.

For more details of how this works see the OpenSeizureDetector web site.
