A way to detect a probable/possible nocturnal seizure (for example from jerking, heart rate jumping suddenly up, etc.) would be sooo warmly welcomed by thousands of epileptics you can’t even begin to imagine…! IMO, this could easily work well enough even without any addons.
And this wouldn’t benefit only those with a diagnose. it is estimated that 10% of all population (yes indeed: one out of ten) gets a grand mal seizure/seizures during their lives, and if it happens during the night when nobody is watching, we won’t even know about it.
Btw thanks for your awesome app.
