The application allows you to create lists of monitored operations, and measure the time for each operation from the list. In addition, during the metering operation, you can take photos and videos, and this data will be associated with the measured operation. Several different observations can be made at the same time. The results of a photograph of a working day or time-keeping observations are uploaded to an archive containing an Excel file with basic information (operation start and end time, operation name, operation comment, etc.), as well as media files created during the observation. The archive is transferred for further processing on a computer by sending these files by e-mail.
