Optimally manage
equipment and materials
Easily record the location, construction equipment, machinery and tools and their use, enabling you to monitor how long they were used, who used them and what results were achieved with them, at all times and just in time.

Keep a construction diary
with a minimum amount of effort
Quickly combine site data with photos, comments, services, construction machinery used, materials and tools as well as the weather and the employees and subcontractors working there. Your digital construction diary is generated automatically.

Efficient, paperless
time recording
Simply record times, photos, services and activities on the construction site or on the road with your smartphone. Fully automatically and in real time, all data are transmitted to the construction office and can be further processed directly by the controlling department. Also usable offline!

Photographic documentation –
optimally protected
Take photos with your smartphone or tablet directly on site and document site security daily—this allows you to maintain a step-by-step overview. Foolproof and legally watertight.

Construction wages and payroll
accounting – more convenient
than ever before
Free up the wages department and avoid wasting time. Our system transfers all the collected data from the construction site to your payroll accounting. Direct, loss-free and fully automatic.

Scheduling –
planned efficiently
Plan and keep track of the use of resources and staff in a jiffy. Our construction site scheduling system also takes account of absences such as leave or further training.
Individual forms –
now digital
