Seizure alert app / apple watch reliability

Hi,

Has anyone got the seizure alert app on their phone or watch? I would buy a watch if it had the ability to detect a tonic clonic seizure. I have an active lifestyle and am often on my own, it would give me great peace of mind to know it could send alerts to a contact, should the worst happen. My seizure are quite rare but still happen (from 3 months to a year or 2).

Any advice or feedback would be appreciated. Thank you :)
