Eureka makes it easy to join real medical studies and help solve the world’s biggest health problems—including heart disease, diabetes, cancer, mental illness, healthcare inequities and more. It’s now easier than ever to have a big impact on causes you care about . All it takes to contribute to world-changing research with Eureka is a smartphone and a little bit of free time. Team up with millions of other study participants helping top researchers from research universities like UCSF, Harvard, and Johns Hopkins to answer questions like, “What signals from my smartphone might predict heart disease?” and “How does physical activity affect cancer risk?” Eureka is a non-profit resource built by researchers at the University of California, San Francisco with support from the National Institutes of Health. If you have questions about signing up or your current participation, reach out to us at support@eurekaplatform.org. For the studies that are on our app, we are not currently pulling HealthKit data but are collecting approval for future use. We use the CareKit framework in our application but do not connect to it in any other way. ## Key features - Join medical research studies - Contribute to health problem solutions - Participate via smartphone - Support top research universities - Track impact on health causes ## What do users think of UCSF Eureka Research?

All that I had done was gone. Now you want me to spend another half hour on your survey and what if it bombs again? ### 1/5 — Crashes when trying to open *2025-04-25, version 1.57* The app for iPhone works fine, but when downloaded the version for the ipad, it crashes instead of opening. ### 1/5 — Way to many bugs and app freezes *2024-07-30, version 1.43* Opted out of the study and deleted the app because this app is way too buggy, and freezes all the time. Extremely frustrating to try to use it. Even after you delete the app they keep spamming you with text messages and no way to turn them off. Stop!! ### 1/5 — App is broken *2024-03-15, version 1.37* You can’t reset your password because the password link that they send expires before you have time to tap in a new password. You can’t contact the program coordinator for assistance because the app won’t let you. Can’t reset the password, can’t login, can’t help out. You really need to get your app fixed. ### 4/5 — Heart or app keeps freezing *2023-12-15, version 1.34* As soon as the heart study in December the page and application freezes so I have to remove app and reload it but hit the home button in app and again all over ? ### 1/5 — Won't run *2023-12-08, version 1.34* I can't tell whether it works as advertized or not. I'm attempting to run it on a Macbook running MacOS 14.1.2 on an M1 chip. And every time I try it, it throws up a window telling me my unit is jailbroken. huh?! I've never heard of a jailbroken macOS. In any event, it won't run so it's worth a no star raring if I could. ### 1/5 — Hangs on “study is no longer available” dialogue box *2023-12-08* I’ve used Eureka to participate in several studies. I had signed up for the healtheheart study, and after completing a lengthy intake survey, when I reopened the app, another study, TREAT, popped up a dialogue box saying it’s no longer available. after acknowledging this dialogue box, it takes me to a grayed-out screen for the TREAT study, and no matter what I do, that screen stays and won’t allow me to go anywhere. The app is now unusable. ### 5/5 — 😕 respond to reviews *2023-01-11* You are hobbling your studies by not responding to each and every review, positive or negative, here in the AppStore. Responding what good developers do. Reasonable people are properly skeptical and hesitant in joining your (worthwhile?) studies when you don’t respond to the very pointed specific criticisms about tracking, etc. which constitute a large percentage of reviews. Make it easy for people to choose to help. Also your website is vague corporate-speak happy talk. Communicate straightforwardly without fluffy marketing verbiage. The short Vimeo video is good. I’m drawn to help as I fully believe in science, but I’m turned off by UCSF’s presentation as well as a lack of response to reviews. Giving five stars now, will sign on and see what actually happens with battery drain — and whether my user experience is not a pain and a time-waster. I hope this criticism reaches someone who can understand and execute. And respond. ### 1/5 — Registrace *2022-10-29, version 1.18* Nejde se zaregistrovat, na české číslo nedorazí SMS. ### 3/5 — Delete app after survey *2022-10-18* After reading that the app tracks you, despite saying it won’r. I delete it each time after answering Covid survey questions. Hope that stops tracking. I notice that now the questions take on a more political survey tone such as whether you have financial concerns. Etc. That’s not Covid health issues. ## Frequently asked questions about UCSF Eureka Research ### What does the UCSF Eureka Research app do?
