Designed for personal health experiments

Chronic conditions aren't simple

There are a lot of variables that can affect your results. We track context like sleep, stress, and triggers, and account for them so your results are as accurate as possible.

Understand where you're starting from

We understand where you're starting from so we can set a baseline for you to compare against. "Future you" vs. "current you."

Guided tests

Experiments can be complicated. We take all the guesswork out of it so you can focus on what you're trying to test.

Plain-language results

You get a clear summary of what likely helped, what didn't, and when it's still too early to tell.

Built for trust
