Lemma Health
Personal Health Experiments
Lemma Health app on iPhone showing daily check-in and experiment tracking

Stop guessing. Start learning.

Most people with chronic symptoms are already trying diets, supplements, treatments, and routines. Lemma helps you turn that trial-and-error into personalized learning.

Not diagnosis. Not a cure. A clearer way to learn what may affect your symptoms over time.

For symptoms without simple answers.

Still guessing what's helping your symptoms?

Magnesium? Keto diet? Vitamin D? Meditation? More exercise? Avoid dairy? No caffeine?

You're not short on effort. You're short on clarity. Lemma helps organize the chaos so your trial-and-error does not get lost.

You're already experimenting.

Track what you tried and what happened afterward.

Learning needs context

Connect what you tried, when, and what changed afterward.

Patterns over time

Less reacting to every flare or bad day.

See whether it's helping — not just a gut feeling.

Compare your baseline to your experiment. Build confidence about what may be helping, not helping, or still too early to tell.

Frequently Asked Questions

Is Lemma Health a symptom tracker?

Lemma Health includes daily check-ins, but it is built for more than logging symptoms. It helps you structure personal health experiments, track what you try over time, and learn what may be helping — with context, not guesswork.

Is Lemma Health for chronic conditions?

Yes. Lemma Health is designed for people managing chronic or recurring symptoms who are already experimenting with diet, supplements, treatments, and routines — and want clearer learning from that effort.

Can Lemma Health help me understand what affects my symptoms?

Lemma Health helps you see patterns between symptoms and the changes you track — treatments, routines, lifestyle factors, and context. It does not diagnose medical conditions. The goal is more confidence about what may be affecting your symptoms over time.

How is Lemma Health different from a regular health tracking app?

Most health apps collect data. Lemma Health helps you learn from it with structured experiments, baseline comparisons, and analysis designed for noisy real life — so you can build confidence about what may be helping, not just log how you feel.

What can I track in Lemma Health?

You can track symptoms, treatments, supplements, medications, skincare routines, diet changes, sleep, exercise, stress, wearable data where available, and daily notes. Lemma connects what you tried to what changed afterward.

Does Lemma Health give medical advice?

No. Lemma Health does not diagnose, treat, cure, or prevent medical conditions. It helps you organize symptoms, experiments, and observations so you can better understand patterns over time and have more informed conversations with a qualified healthcare professional.

Do I need to understand statistics to use Lemma Health?

No. Lemma uses structured experiments and Bayesian analysis in the background. You get plain-language results about whether a change may be helping, not helping, or still too early to tell.
