As part of the d2smell project, we want to find out what people smell every day. Learn about olfaction and see what others have smelled. Get paid for participating in research into the sense of smell. 4 times a day, at random times, the app will ask you to fill out a questionnaire on what you smell. Get a bonus for completing 40 surveys over 10 days.
