The present invention is directed to a computer application for seizure detection using biometric data and responsivity testing. The computer application collects biometric data and responsiveness test results from biometric sensors and an interactive user interface in order to identify and confirm seizures and monitor for severity, duration, and permit logging and notification. The computer application collects data such as heart rate, movement, and responsivity testing results. The computer application facilitates caregiver notification of seizures at or before seizure onset if the user has a warning aura and/or during prolonged or severe seizures (e.g. long duration or convulsive movements).
