Start my experiment See what you'll track

Lemma Health helps you understand what may help your chronic condition by spotting patterns, testing changes, and learning from your data over time. It does not provide medical advice or replace a clinician.

Your experiment, simplified

Try → Test → Track → Learn

Try something new

Pick a treatment or change you want to try for yourself.

🧪

Set up a test

We help you create a test to see if the change helps.

🗓️

Track consistently

Check in daily and monitor your progress.

📈

Learn what works

Get simple results and learn what helps.

How it works

Simple steps that take you from "maybe" to "I know".

Your path

Current you

Answer a few onboarding questions so Lemma Health understands where you're starting from

Choose what to test

Pick what you want to try and how you'll measure success

Run the experiment

Check in daily and monitor your progress

Get results

See whether it helped, hurt, or was inconclusive

New you

Decide whether to adopt the change as your new baseline

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.

Better than going it alone

Most apps just let you log symptoms. Lemma Health actually tells you what's working — and how sure you can be.
