Hi Petersfamily
We purchased the Apple Watch for my daughter and have got the Seizalarm app which is great. It detects seizures and sends an alert to me (or numerous other contacts)- and also sends the location in an SMS. Luckily since having it, my daughter hasn’t had any more tonic clonic seizures but I find it very reassuring when I have to leave her on her own (she is 16 and so needs her independence). It means she can have a bath etc which I would never allow otherwise.
it is quite sensitive to changes in heart rate but you can adapt the sensitivity. If it is a false alarm she can cancel the alert. It costs £15 a month for the app
subscription in the Uk but I believe it is worth every penny. Hope that helps!?
