About this app

Open Seizure Detector is an epileptic (tonic-clonic) seizure detector / alert system that utilises a smart-watch to detect shaking or abnormal heart rate, 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

Please see the Installation Instructions (https://www.openseizuredetector.org.uk/?page_id=1894) for help with setting up this app.

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.
Note that the app will give false alarms for some activities that involve repeated movements (brushing teeth, typing etc) so it is important that new users spend some time to get used to what will set it off and use the mute function if necessary to reduce false alarms.

You need a Garmin Smart Watch that is connected to your Android device for OpenSeizureDetector to work.. (it also works with a Pebble Smart Watch if you have one which is connected to your Android device)

The system 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. We do however provide a 'Data Sharing' service to allow users contribute to the development of OpenSeizureDetector by sharing the data collected by their device to help improve the detection algorithms.

I recommend subscribing to email updates to the OpenSeizureDetector web site (https://openseizuredetector.org.uk) or Faceobook page (https://www.facebook.com/openseizuredetector) if you use the app so I can contact users if I find an issue you should know about.

Note that this app has not been subjected to clinical trials to confirm its detection reliability, but I have had some positive feedback from users saying that it has detected tonic-clonic seizures reliably. We hope to improve this situation by using data provided by users with our Data Sharing system
See also https://www.openseizuredetector.org.uk/?page_id=1341 for some examples of it detecting seizures.

For more details of how this works see the OpenSeizureDetector web site (https://www.openseizuredetector.org.uk/?page_id=455)

Amazing app, thank you developer. Sends a text message alert when it senses a seizure occuring (via a Garmin watch). Note that in Android 11 I can't get the location text to send (even with location permission switched on), but as a workaround, in Google Maps I have my location permanently shared with my wife.

I'm glad you find it useful. I had forgotten about the location issue - will see if I can fix it.

I was very excited for this app. Got the new watch to go with it and everything. I just completed an ambulatory eeg this past week and the results show that when the watch detected a seizure and I recorded it and pushed the button, there was no seizure. It's a nice try, but not accurate.

I think what you are describing is what I call a False Alarm. False alarm rate is one type of accuracy. The other is the seizure detection rate - what proportion of genuine seizures did it detect correctly? Please email graham@openseizuredetector.org.uk and I will have a look at what you can change in the settings to improve performance.

Works great and graham is very responsive and caring and wants each customer to be safe and will do anything to get it up and running, just provide photos and detailed information about devices about the issues and he will get you up and running. He learned some tricks of issues through my installation issue so he is prepared for what's next, just stay calm and patient.

What's new

Minor update to fix occasional silent crash reported by two users - we regard silent crashes as being very serious because the intention of OpenSeizureDetector is that it should give fault 'pip' sounds to notify the user if it is not working correctly. (https://github.com/OpenSeizureDetector/Android_Pebble_SD/issues/135)
