We are taught almost nothing about breasts. The Know Your Lemons^® app fixes that. Introducing the world’s first app designed to improve early detection for breast cancer—with a twist of lemon. Learn how to self-exam, 6 ways to identify the 12 symptoms of breast cancer, track your period, take a risk quiz and get a custom screening plan to make knowing when to get a mammogram crystal clear.

The ONLY period tracking app nominated for a Webby Award in 2022.

Our app makes it easy to self-exam, report changes, calculate your risk, and keep your regular screening appointments. It’s designed by women, and we don’t collect your data either.
