Our science based humanitarian mission
We have created a team of multinational scientists and global industry giants to develop a test to identify olfactory dysfunction. Our aim is to detect the loss of smell with daily testing anywhere, anytime.
Our pledge is that every u-Smell-it test sold, we will donate another to a developing country.
Validation comes from science.

Why target smell? Our nose knows
Our nose is where viruses can enters and multiply, therefor wiping out one’s ability to smell. For instance in Covid-19 the CDC has shown that loss of smell is as an early symptom that is better associated with Covid-19 than any other symptom. It was reported here that >80% of asymptomatic people have a partial loss of smell that can only be detected with a sensitive olfactory test.

5 Reasons to use the ‘u-Smell-it’ test to check for loss of smell (anosmia)
1. Fast
The test only takes ~45 seconds with instant results.
2. Easy
It is simple and uses an app to automatically score your results. Therefor can be done anytime anywhere.
3. Affordable
u-Smell-it test is a very affordable and can be used daily.
4. Credentials
Secure and encrypted & no names or personal info
5. Validation
The u-Smell-it™ test has been bench-tested, field tested, and is being used in multiple clinical trials.
Modelling shows an olfactory test could flatten the Covid curve
A modeling study showed that the simple olfactory test if used widely and frequently could have a dramatic effect on the number of people infected with COVID-19. If used every 1-3 days an olfactory test such as u-Smell-it™ may even outperform a weekly PCR test, for a fraction of the price. Parameters that effect the performance are discussed in the paper.
Disclaimer: The founder of u-Smell-it (Dr. Toomre) was an author on the study, but the values used for the model are based on a wide body of published literature and the modelers have no affiliation with u-Smell-it™.
