We’ve developed a simple test to measure your sense of smell.
You’ll take a smell test twice, with each session lasting about 45 minutes. After completing the first session, you’ll take the second one six weeks later. You will be compensated $30 per completed test for a total of $60.

You Will:
- Smell odors by lifting the labels on the disposable smell cards in front of you.
- Enter the responses into the app on your phone, tablet, or computer. **For the best experience, we recommend using a tablet or computer.
- For all subsequent smell tests, use the link in your email or the returning user button below.
