Time tracking on construction sites was never easier
Put an end to time sheets on paper. Our market-leading mobile time tracking app allows your on-site team to easily record working times. Both individually and for an entire crew. The system automatically assigns the times to the corresponding construction sites, components and work areas. Recorded times, locations and activities are then digitally transferred to your office for real-time billing and daily construction reports. At the same time, the processed data can be shared with all project participants.
