Boston Children's Hospital invites you to join this study about body temperature to enhance our understanding of temperatures in a large diverse population of children and adults.

Fever is one of the most common signs of illness and causes anxiety to many. Surprisingly, doctors still struggle with determining the cause of a fever. In addition, "normal" and "febrile" temperatures vary between individuals. Better understandings of how body temperature varies between individuals and identification of disease fever patterns (“feverprints”) could allow doctors to make faster, more accurate diagnoses. With the data from this study, we hope to improve our ability to determine the cause of fevers.

In addition, this app can be personalized for you to track body temperature, symptoms and medications when the participant is sick. Through this app you can access several resources to help you understand fevers and related symptoms.

The app integrates with Apple's Health App to pull body temperature data recorded through other connected devices that support HealthKit integration. In addition based on user's permissions the Feverprints app writes body temperature entries back to HealthKit.

How this study works
- You will be able to join the study after signing the consent form.
- We will ask you to regularly measure your temperature and answer questions about your health.
- If you own a thermometer that connects to your iPhone, we will automatically upload this information into the app. All of the information we collect is anonymous, meaning that we won’t record your name or other personal information.

Who is eligible to participate?
- Children and adults living in the United States who have access to an iPhone and a thermometer can enroll.
- Children under 18 years of age will need parental permission to participate, and those ages 7-17 will also be asked to provide assent.

Who is running this study?
- Doctors and researchers from Boston Children’s Hospital and Harvard Medical School.

Happy to help

My 2 daughters and I are happy to help people learn about fevers and body temps. I’m not using this app to track fevers, only to help us all have a better understanding. Thank you for your efforts!

Lose data

If you track fevers, don't rely on this for your data. Once entered, there is no way to retrieve any older data. Forgot to add fever info to the other place I track it, went back to look for it, it's gone, and there's no way to search for or retrieve it. Extremely disappointed and will not be using anymore.

Excellent, But could use a few more features

There is an option for "Rash" & "Skin Rash" better descriptions of what qualifies in which category would be helpful. I would also like to see options to add symptoms and medications that are not already on the pre-programmed lists. Like for the last week with each NOD2 Associated AutoInflammatory Disease flare I also had Livedo Reticularis. Also, my medications I take we're not on the list so the information is inaccurate. The interface is excellent and simple to use. The above are the only suggestions I would make for the entire app.
Thank You!
