Open PVT

Open PVT is a psychomotor vigilance and reaction-time testing application. The app provides configurable 3-minute, 5-minute, and 10-minute test sessions in which users respond as quickly as possible when a visual stimulus appears. Open PVT records trial-level and session-level measurements including reaction times, lapses, false starts, timeouts, session timing, and summary statistics. Features include: • 3-minute PVT-B testing • 5-minute modified PVT testing • 10-minute standard PVT testing • Reaction-time feedback • Lapse, false-start, and timeout tracking • Session history • Trial-level data review • CSV export for data analysis • Local on-device data storage • No advertising • No automatic cloud upload Test data remain stored locally on the device unless the user explicitly exports or shares them. Open PVT may be used for educational, analytical, or research-related purposes, but the app itself does not enroll users in studies or provide clinical services. Open PVT is not intended to diagnose, treat, cure, prevent, or provide medical advice regarding any disease or medical condition.
