What is Moodmon?
MoodMon is a CE-marked Class IIa AI-powered medical device for continuous, objective monitoring of patients diagnosed with affective disorders, that is bipolar disorder (BP) and recurrent depression (MDD).
Early detection, timely intervention
MoodMon supports psychiatrists in ongoing patient care by helping identify clinically relevant changes in a patient’s mental state at an early stage and enabling timely clinical intervention. It helps patients in controlling their condition and caregivers in everyday care of patients.
Care beyond appointments
By extending patient monitoring beyond individual appointments, MoodMon aims to support earlier intervention, more personalised care and better use of healthcare resources – while giving patients greater confidence and support in managing their condition.
How it works
The system gathers physical parameters of the patient’s voice and behavioural data from a smartphone and wearable device, including physical activity, sleep and smartphone usage.
MoodMon’s AI analyses voice parameters and generates alerts when patterns indicating a potentially clinically relevant change are detected. Alerts are sent to the clinician, the patients and indicated caregiver(s).
Other data are provided in graphical form to the clinician as supporting material. This provides psychiatrists with objective information between appointments, complementing their clinical assessment and supporting treatment decisions.

Mobile App
Daily Mental Health Monitoring
The MoodMon mobile app primarily collects voice samples through two convenient methods: a voice questionnaire started by the patient or an automated voicebot call at a time chosen by the patient. Both methods involve answering emotionally neutral questions. The system analyzes how the patient speaks – the physical characteristics of their voice – not what they say.
The app also collects data on physical activity, sleep, and smartphone usage, including information from a connected wearable device. Patients can also complete a self-assessment questionnaire. These additional data are displayed to the psychiatrist as supporting information for clinical assessment but are not analyzed by AI.
Desktop Platform
Monitor and Manage Patients’ Mental Health
The MoodMon web platform supports psychiatrists in monitoring patients between appointments. It provides access to AI-generated alerts, clinical assessments, and complementary behavioral data on patients’ sleep, physical activity, and smartphone usage.
MoodMon’s AI analyzes voice parameters daily to identify potentially clinically relevant changes in a patient’s mental state. When such a change is detected, an alert is generated and made available to the psychiatrist in the web platform and to the patient in the mobile app.
An alert provides a basis for contact between the patient and their psychiatrist, initiated by either party. The psychiatrist can then assess the patient’s condition, review supporting behavioral data, and document their clinical evaluation in the system.
By combining AI-generated alerts with clinical expertise and additional patient data, MoodMon supports timely intervention and informed treatment decisions.


AI Engine
AI-Powered Insights for Personalized Mental Health Monitoring
At the core of MoodMon is a proprietary AI engine that analyzes physical parameters of the patient’s voice to identify patterns indicating potentially clinically relevant changes in their mental state. The system generates a daily AI-based assessment and alerts patients and their psychiatrists when significant changes are detected.
Psychiatrists provide clinical feedback by evaluating generated alerts and assessing patients’ mental state during routine appointments, including periods when no alerts were triggered. This feedback is used to train and refine MoodMon’s AI algorithms, supporting more accurate and personalized monitoring over time.
