TRAC is a web-based research software for time-use research: users can report what they did during one or more days by selecting activities and placing them on one or more timelines per day. E.g., depending on the study, there may be one timeline for 'Primary Activity', and another one for 'Secondary Activity', allowing users to report things like listening to music while riding on the subway.
The frontend is based on github.com/andreifoldes/o-timeusediary by Andrei Tamas Foldes et al. but heavily adapted, and the backend was written from scratch.
When using the software in this repo, please also cite Andrei Tamas Foldes' paper Time use diary design for our times - an overview, presenting a Click-and-Drag Diary Instrument (CaDDI) for online application.
NOTE: Recently the frontend and backend repos were united into this one repo, so for now, you will have to see the frontend and backend directories, and the README files in there, for more details.
