ChronNow
Time tracking for people who forget to log their hours under stress. A small program on the Windows machine records the time from sign-in to sign-out; entries can also be added manually. Evaluation is by project, so there's no guessing at the end of the month. Currently in beta.
BauTrupp
An app for the construction site: time tracking, photos, material reports, and a site diary, plus management tools for the office. It works offline, since there's rarely a network connection on a construction site. Spoken notes are turned into text by AI and land in the right field. It grew out of a conversation with a construction company about the daily processes that cost them time.
