Apps for patients with epilepsy

I've been searching since the past few months for apps that track seizures for patients with epilepsy and record seizure events whenever a seizure is about to happen. Sometimes it is hard to call for help especially if the patient can't control these seizures or don't see any signs. Therefor, an app that records detailed seizure events and has an alarm feature to call for help whenever is needed Is something really great to have. So, any app suggestions?
I think this feature should be included on the Apple Watch next generation. We strongly suggest users to write to Apple requesting this feature. This will make things easier for patients and doctors to follow up. I find it hard to write data about the last seizure event because it's possible to forget what happened during the seizure.
