The online report books of the gardeners (gardening and landscaping or that of the other horticultural disciplines) are now available as a joint app. The app offers the opportunity to write the training certificate and the additional construction site information or activities, to make notes and to take photos. If desired, all recorded content and images of the app are automatically synchronized with the respective online report booklet (gardening and landscaping or other horticultural disciplines) as soon as a W-LAN connection is established.
