Clinical

Apollo is thymia’s clinical assessment model. From just 15 seconds of natural speech, Apollo analyses neural morphemes™ to produce clinical-grade assessments of major depression and generalised anxiety — including disorder-level probabilities, granular symptom scores across all core DSM-V criteria, and a downloadable clinical report.

Designed for use by healthcare professionals, Apollo supports remote and rapid mental health triage, enabling precise individual symptom quantification, objective efficacy measurement, and enhanced patient stratification — without requiring an in-person assessment.

Apollo is a regulated medical device. It is intended for use by qualified healthcare professionals only and must not be used as a substitute for clinical judgement. Apollo is not intended for self-assessment or consumer use.

For non-clinical wellness monitoring, see Helios.
