Zest is an app that uses AI to give you personalized longevity protocols and the most accurate biological age test on the market. Combined with home blood testing and supplements, Zest is a complete end-to-end solution for longevity.

We started Zest to solve two big problems in longevity science. 1 - People just want to be told what to do. They want to live longer, healthier lives but don't have time to personally do all the research. They just want a trusted source of information to give them a personalised daily longevity protocol. 2 - Tracking progress is really difficult. Plenty of people spend thousands on supplements, bloodwork, nutritionists, personal trainers etc. and have no idea if it's even working or is worth the money. They need a way to accurately track their age on the inside. The solution: Our team of medical doctors and longevity scientists have built this tracking app which tells you exactly what to do each day to maximise your healthy lifespan. We also have our own AI-backed biological age score which is the most accurate on the market. The more you interact with the platform, the more accurate your biological age score, and the more personalised your longevity protocol. Let us know what you think!

@juliacooney this is great idea and I am glad it's being tackled by a doctor and not some techie. As others have said, it would be nice to read more about the science behind this service.

Your approach to providing a personalized daily longevity protocol and accurately tracking biological age is great. I recently read 'Outlive' by Dr. Peter Attia, and it piqued my interest in longevity science. Have you read it?

Cool design. Congratulations on the launch.
