Olfaction is the least charted of the human senses. Join D2Smell and help map it, out side of the lab, in the air we actually breathe.
SMELLiT is an app behind a collaboration project spanning 4 labs across Europe, the D2Smell project. Funded by the European Research Council, it studies human olfaction where it actually happens - in kitchens, on streets, on buses, in the air you move through all day without thinking about it. Every report you send is something no laboratory could have produced.
WHAT YOU DO
Four times a day, at random moments, the app asks simple questions: can you smell anything right now? What is it? How long have you been smelling it, and where? Together with the pictures the and the free description of the smell you will provide, this first of its kind database will go a long way helping the olfaction research march forward. The times are random on purpose. The smells you notice when you go looking for them are not the smells that make up our naturalistic daily live.
WHAT YOU GET
Get paid for taking part in real research. Complete the study and receive a gift voucher by email, with a bonus for finishing all 40 questionnaires. If you would rather your participation simply contribute to the science, you can waive the payment instead.
After you finish, an elaborated portfolio of your nose type will be provided: where does YOUR nose fall relative to everyone else? It is not a race, and there are no right answers, so trying to hard will actually hurt your results. Be your true self, and you will find your true nose. :)
YOUR DATA
The study is approved by the Weizmann Institute of Science Institutional Review Board. You read and accept a full consent statement before anything is collected. You can find more information in out Privacy Policy statement.
LANGUAGES
SMELLiT is available in 13 languages: Arabic, Danish, English, French, German, Hebrew, Icelandic, Italian, Japanese, Portuguese, Russian, Spanish and Swedish. Arabic and Hebrew read right to left throughout.
Join D2Smell, and use your nose to help discover what the nose knows it knows.
It has never counted a questionnaire I did, even after doing it several times

THIS APP IS NOT WORTH IT WHY BECAUSE EVERY TIME YOU GDT A NOTIFICATION FOR A SURVEY YOU GET KICKED OUT AND YOU HAVE TO LOGIN IN WITH YOUR PHONE NUMBER AND VERIFY YOUR NUMBER TO LOGIN IN!!!!!!! IS THIS GOING TO BE EVERY-TIME I ANSWER A NOTIFICATION???? FOR THIS I HAD TO CANCEL THE EXPERIMENT AND MY ACCOUNT
Thank you for being part of SMELLiT. This is a big update.
RATING WHAT YOU SMELL
The rating scales have been redesigned. Rather than choosing from a fixed set of steps, you can now place your answer anywhere along a smooth scale. It is a more natural way to say "somewhere between these two", and it gives the research a far more precise signal.
TAKING A PHOTO
The photo step has been rebuilt. The camera now stays oriented with your phone, so a picture taken sideways is saved the way you actually held it, and switching between the front and rear lenses is quicker.
YOUR LANGUAGE
SMELLiT now speaks 13 languages, with translations reviewed line by line. Arabic and Hebrew read right to left throughout. You can change language at any time in Settings, and during setup you can now step back to the language picker instead of starting over.
GETTING IN TOUCH
There is a Contact us page inside the app. Write to us directly, attach a photo if it helps explain something, and follow the reply without leaving SMELLiT.
READING COMFORTABLY
Every screen has been checked at large text sizes. Nothing overlaps, nothing is cut off, and buttons stay reachable however you have your display set.
REMINDERS
Notification timing is more reliable, particularly around midnight and when traveling between time zones.
ALSO IN THIS RELEASE
International phone numbers are handled correctly whether typed or pasted, and in any digit system. Offline and connection messages are clearer. Plus a long list of smaller fixes and a good deal of polish throughout.
