A tracker is a device, software, or system designed to monitor, record, and analyze data related to movement, behavior, or performance. Trackers use sensors, GPS, or algorithms to collect real-time or historical information for personal, commercial, or scientific purposes. Common types include fitness wearables (steps/sleep), GPS devices (location), and software (time/finances). Used for optimization, safety, and research across industries.
