I really like that the app and tracking is so easy, with just a few items to log. And I like the reminders. Not too many, but enough to remind me to do logging.
Eureka helps me remember if I took my medication, measure progress (or declines) in my health, and understand correlation between interventions & outcomes. I couldn’t do it without Eureka and I’m really thankful to have the app to help me.
Eureka is a really intuitive and easy tool for me to track my long covid symptoms and how they’re changing over time. I’m so happy that I can look back on months of data and see improvements in my health based on what I’m trying!
I am enjoying the app and the reminders to take my LDN and to record my results at the end of the day. The support is absolutely amazing.
I’m really grateful that Eureka exists, I’ve been experimenting with how to improve my health for as long as I can remember, and until now, I’ve never found an app which helps me learn whether what I’m doing actually works!
Spoke to this team yesterday - they’re really trying to create something that makes a difference!

There’s no silver bullet, so trial-and-error is necessary to keep making progress. Eureka helps you move quickly and dial in what works for you.
Frequently Asked Questions
Eureka’s mission is to discover and validate new treatments and cures 10x faster than what’s possible today. Existing clinical trials are slow, expensive, and ignore entire categories of potential treatments. By empowering a thriving community of patients, researchers, and doctors with cutting edge technology, we think we can do better.
Eureka is an information hub that aggregates and summarizes the latest information on promising new treatments. It’s fed with data from the latest scientific studies, and from the patient community tracking how things are impacting them.
Telling patients to “sit tight and do nothing” for years while clinical trials are completed just doesn’t cut it. We’re all hungry to learn more about what’s out there, and what we can do today. With that said, we’re only providing information, not medical advice, and any experimental treatments should be taken under the supervision of a trained clinician.
No. We’re here to help you discover your options, and to help you track the impact if you do end up trying something, but you should always check with your doctor to ensure a given treatment is right for you.
Anyone with a web browser can browse Eureka programs. Our app is currently only on iOS, but we have plans to support Android soon. Note that we're not on the app store yet, so you'll need to use the Testflight invitation in your email.
We’re focused on helping you figure out the impact of new treatments you’re trying, rather than just tracking how you’re feeling over time. We also provide a clearer picture of how your Long Covid or ME/CFS is progressing, with wearable metrics (HRV, Resting Heart Rate, Sleep Quality, SP02, and others) and validated self-reported symptom surveys.
It’s totally free! We strongly believe that all patients should have access to the best information and best tools, not just those who can afford it.
In cases where it’s valuable for you, we plan to provide (clearly marked) “sponsored” products and services. If you purchase a supplement via a Eureka affiliate link, we make some money (for no additional cost to you) and you help support the community.
We feel strongly that your data is yours alone, and use state-of-the-art encryption to ensure your data is safe. You’re free to share your data with the community or with approved researchers if you’d like.
No. Diagnosing these diseases can be tricky, and we’re here to help anyone who thinks our app could be useful for them.
