Description
See https://openseizuredetector.org.uk for details.
Open Seizure Detector is an epileptic (tonic-clonic) seizure detector / alert system that utilises a low cost (~£35) PineTime smart-watch to detect seizure-like movements, and raises an alarm for a carer. It can also be configured to use a Garmin smart watch to raise alarms based on measured heart rate in addition to movement.
If the system detects seizure-like movement, it can raise alarms in one of three ways: - Local alarm - the phone emits an alarm sound. - 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 away from home it can be configured to send SMS text message notifications that include the location of the user.
Please see the Installation Instructions at https://openseizuredetector.org.uk 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, using hand tools 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 PineTime or Garmin Smart Watch that is connected to your Android device for OpenSeizureDetector to work., but you can use the motion sensor in the phone as a 'demo mode' to see what the app will do.
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 Facebook 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. An analysis of its performance is published here for reference: https://openseizuredetector.github.io/pages-user/PineTime_Performance_Report.pdf

I have been testing this app as Graham has Created and updating it. It must be understood by anyone downloads this and using it, it is a one person and one test person show. This was done for all to use because we share the fact that our children have nocturnal seizures. I was on my path with one and Graham on his path. His is the most affordable option currently available. To make this affordable ONE platform was chosen. Pebble watches are 89 dollars US. Android 4.0 devices can be had for less than 40 bucks in some instances. Yes, it would be nice to have cake and eat it too, but again, this is a ONE-person developer. I am a fervent backer and tester of his project. But there are no "developers". There is just a "Developer" (singular). If Graham is able to port this to other watch platforms I am all for it, as yes, it would make it easier for others who already have other platforms. For those that don't, affordability is/was key. Just a note from someone who has used this for over a year now with a child who has nocturnal seizures.

I just installed the seizure detector on a garmin bioactive 3 and first tests worked fine. Thanks, Graham, for good support and pointing me to this new version!

I was very excited about 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.

Does not work on the Garmin Venu 3 as everything online said it would work best with this model. It won't download on the Venu 3 at all. Samsung with EpiPal worked better than this for less investment. App barely works on phone too and just sends endless emergency texts to my emergency contacts but won't send false alarms. Again, does not connect to venu 3 at all
