Glow facilitates easy sharing of health information with CareKit

Women in the United States make approximately 80% of health care decisions for their families. These decisions aren’t made lightly—they often involve hours of research, and enlisting the help of family, friends, and medical professionals. Keeping this information organized and keeping everyone in the loop is crucial.

At Glow, we make mobile apps that empower women with health information. Our support begins when a woman gets her period and extends through parenting, when she becomes a central caretaker and starts to assume responsibility for the health of her loved ones.

Being a central hub of the family’s health information often requires sharing information between various parties. Knowing how much our users want to transfer their data to family members, doctors, or other caregivers, we were thrilled when Apple told us about the idea of CareKit.

CareKit’s Connect module enables fast, easy sharing of health information among family members, medical professionals, and caregivers of all kinds. For our Glow users, this means an ability to not just collect information in the app, but share that information with relevant parties and develop a solution faster.

Our apps anticipate the kind of data entries that should be shared between parties, and we leverage smart notifications to prompt users to visit the Care Team page, where they can transfer data right away. For example, a mom who uses the Glow Baby app to note that her baby has a fever will receive a notification directing her to share the information with the pediatrician, babysitter, or wider family on the Care Team page. In our Glow Nurture pregnancy app, Care Team notifications surface when a user indicates that she feels sick and when important prenatal appointments draw near.

Providing tools to make health management easier for women and families is core to our mission, and CareKit enables us to serve our users better in this regard. Better and easier sharing of information with all caretakers—doctors, nurses, partners, parents, babysitters—is another important dimension for taking control of one’s health.

CareKit + ZeroKit: Protect patient data in the cloud

Technology can improve patient lives in ways not seen before. Yet risks to data security interfere with innovation. Massive data breaches are all too common turning stolen patient passwords, personal identity, and medical records into articles of trade. To realize the true potential of mobile technology for patient empowerment, security concerns must be tackled.

Apple designed the iOS platform and CareKit with security at its core. When building apps where data is shared across devices and with other services, developers want to extend this security to the cloud. This is exactly what ZeroKit does.

Starting today, CareKit developers can use ZeroKit in their apps. ZeroKit complements CareKit: it’s a "Zero Knowledge" User Authentication service and Encryption SDK that enables developers to protect PHI (Protected Health Information) with the best available methods in the cloud. Using ZeroKit, CareKit developers can reach HIPAA compliance easier which attracts patients and healthcare providers who are looking for the most secure solutions.

ZeroKit offers the following:

1. Authentication of Patients/Healthcare Workers: ZeroKit takes care of user registration and login for your app. The service uses PAKE (Password-authenticated key agreement) technology which does not store password hashes, making it immune to "pass the hash" and safer against brute force and dictionary attacks. The SDK supports Touch ID authentication and also allows developers to never see their users' passwords.

2. End-to-End Encryption of Health Data: using the SDK, you can encrypt health data of authenticated patients. Before data moves to the cloud, PHI gets encrypted on the patient's device and remains encrypted throughout its life (over the wire, on servers and at rest). The encryption keys never leave the device in an unencrypted form. The next time data gets decrypted is when it's displayed on the doctor's device. Even in case of a breach to the servers, records are only visible in encrypted, unreadable form.

3. "Zero Knowledge" Sharing of Health Data: The "Zero Knowledge" key management technology enables secure sharing of encrypted patient data without exposing the data or keys to anybody or any service. Combined with ZeroKit's User Authentication service and CareKit's default file system encryption, this architecture protects PHI from breaches, while providing a seamless experience to your end-users.

The SDK is available for iOS (Swift), Android (Java) and web browsers (JavaScript). Despite the complex technologies used (PAKE-powered user authentication, End-to-End encryption, "zero knowledge" key management), the SDK doesn't require any previous knowledge of security:

ZeroKit is used by healthcare apps such as The Diary in the US & Asia to coordinate community care and hospital monitoring of discharged patients, in Europe that enables patients sharing their health and personal health data with their doctors in the cloud and by consumer apps such as Caret, the living address book that personalizes presence info with context & interactive services.

Beth Israel Deaconess Medical Center empowers patients with new iOS App

Beth Israel Deaconess Medical Center, a teaching hospital of Harvard Medical School, has developed BIDMC@home, a new app for engaging patients using Apple’s CareKit and ResearchKit frameworks and the HealthKit API. The app provides a flexible framework to help patients manage their health from home, as directed by their physicians. The app will be piloted in several specific patient populations and will eventually be offered to BIDMC’s entire network of over 250,000 patients.

BIDMC@home provides personalized home monitoring in many different conditions. HealthKit allows the app to collect data from various sensors and 3rd party apps to gain a holistic picture of health and help prevent hospital readmissions. Together with HealthKit-enabled wireless devices such as scales and blood pressure cuffs, patients with congestive heart failure can use BIDMC@Home to monitor vital signs and symptoms. Daily fluid, sodium intake and important predictors of fluid retention, can also be imported via HealthKit. Connected thermometers allow patients with autoimmune diseases such as lupus and rheumatoid arthritis to better predict infections and monitor inflammation. Outpatient chemotherapy is associated with varied symptoms and side effects. The app allows these patients to better monitor their health during treatment.

BIDMC@Home simplifies complicated post-operative instructions given to patients after orthopedic surgery by utilizing the dynamic care card and allowing them to track their recovery. Major bowel surgery can place patients at risk of severe dehydration. Connected scales and electronic patient reported outcomes will help prevent complications in these patients in between visits to the doctor’s office.

The app contains several key functions:

Care Card:

Every patient has a customized care plan that is seamlessly synced from the electronic medical record via FHIR interfaces. All outpatient medications are listed and updated in real time when a provider makes a change. Patients are encouraged to adhere to their prescribed medication regimen and can also track their intake of “as needed” medications. Providers can also define a care plan for non-medication activities, such as: diet, exercise, sleep or other instructions tailored to their individual care.

An essential part of staying healthy is the plan and thought process laid out in the health care providers’ notes. All too often these are hidden in the silos of individual electronic health record systems. BIDMC@home harnesses the capabilities of the Health app in iOS 10 to serve as a secure, patient controlled, shareable database of medical records. Under the umbrella of the Open Notes initiative pioneered at BIDMC, patients will be able to view and download their physician’s notes from BIDMC, transforming their phones into true personalized health records.


As part of each patient’s individualized care plan, he/she is prompted to provide subjective and objective data to monitor health. These data include values that are synced via HealthKit from connected sensors or other apps (e.g. weight, blood pressure, heart rate, temperature, daily sodium intake) and subjective assessments. Using the ResearchKit framework, the app collects meaningful patient reported outcomes using simple questions (e.g. shortness of breath on a 0-10 scale) or more elaborate validated survey instruments.


To empower patients to take control of their own care, the app provides a dynamic graphing engine so that patients can see the relationship between measurements, medication adherence, or amount of “as needed” medications taken and the direct results. By reinforcing the relationship between treatment and outcome, we hope to reinforce positive behaviors and improve treatment compliance.


The app syncs with our secure messaging system and allows patients to quickly contact their care team members.

Johns Hopkins Medicine Leverages CareKit to Empower Patients in Heart Attack Recovery

Patients who survive a heart attack have a long road to recovery which can be daunting and overwhelming for both them and their families. There are many unknowns after this major life event and patients may get limited answers to their questions, while in the hospital and head home with only a piece of paper to rely on for recovery instructions after discharge.

A perfect example is Mr. Sami Badra, a 30-year old heart-attack survivor. Sami recalls, “I was not using my time in the hospital properly…lying around and watching a lot of TV.  In the last two hours before leaving I was given instructions, but never fully understood them. I left the hospital feeling alone.”

Johns Hopkins medical and cardiology physicians, Francoise Marvel, M.D. and Seth Martin, M.D., and colleagues Matthias Lee, Gavi Rawson, Jal Irani, and Ali Afshar, recognized a need for a resource that heart attack survivors could use from day one in the hospital through discharge and recovery to aid in a successful recuperation and ultimately a heart healthy life. The multidisciplinary team established synergistic collaborations across the Johns Hopkins University including the Whiting School of Engineering, The Johns Hopkins School of Medicine, The Johns Hopkins School of Nursing, Carey School of Business, Arts as Applied to Medicine, Center for Innovative Medicine, Technology Innovation Center, Patient Safety Advisory Board, Patient Family Advisory Council, and community partnerships with YMCA and the American Heart Association to create the first cardiology CareKit App, called Corrie (Cor is Latin for heart).

The Corrie app, paired with the Apple Watch, offers the following:
Watch the video

1. Welcome Page: preview of the Corrie App features and sign-in.

2. My Activities: track progress taking medications and completing other care tasks like engaging in physical activity. Reminders are included to help patients stay on track.

3. My Vitals: stay in tune with indicators of recovery like heart rate, blood pressure, physical activity, and mood.

4. My ABCs: empower with heart health understanding through engaging state-of-the art videos and easy-to-read summaries addressing life-saving cardiology topics including understanding why heart attacks happen and tips on how to prevent them in the future (ex. medications, diet, exercise, and smoking cessation). Patients, families, and caregivers can easily share in the learning experience by engaging with these videos on their mobile device and via Apple TV in cardiac unit hospital rooms during their stay.

5. My Follow-Up: schedule and track follow up appointments with doctors and cardiac rehabilitation.

6. My Connect: keep critical health information a click away, including medical cards (e.g., stent cards, insurance cards) and care team contact information.

7. Apple Watch Combined with Corrie App: monitors cardiac recovery (steps, heart rate, activity goals) and keeps patients on track with medication reminders and doctor’s appointments that are critical for successful heart attack recovery.

Starting this fall at The Johns Hopkins Hospital and Johns Hopkins Bayview Medical Center in Baltimore, the MiCORE (Myocardial infarction, COmbined device, Recovery Enhancement) clinical study will enable heart attack survivors to use the Corrie app on their iPhone and Apple Watch. The study will investigate how this app can help empower patients, such as Sami, and help answer the elusive question of “now, what?”

HomeHero: Leveraging CareKit to Collect Patient Data in the Home

At HomeHero, our vision is to extend the care continuum into the home. Our registered and trained caregivers (“Heroes”) work daily with patients, collecting critical patient health information. Via the Hero iOS app, our Heroes manage patient care, assist with activities of daily living (ADLs), coordinate transitional care for discharged hospital patients and help monitor and record patient health. We use the patient data we collect to prevent negative adverse events — ultimately reducing readmissions and improving patient outcomes. But how do we organize and display this health data in a way that is compelling and easy to digest for caregivers, family members and case managers in the hospital? Enter CareKit.

The Care Card module condenses multiple layers of daily tasks into a simple indicator for each day of the week. Meanwhile, the Symptom Tracker provides a template to power both our Home Safety Assessment and Patient Health Survey to document environmental and behavioral health risks with easy “Yes/No” responses. CareKit’s open-source nature also allows us to maintain our own brand and style for the custom toolbars while giving us the ability to protect patient privacy — patient health data stays safely stored on our HIPAA-compliant servers.

On June 23rd, we officially launched the new HomeHero app as part of our Safe Transition Home program with Cedars-Sinai Medical Center, the largest nonprofit academic medical center in the Western United States. The program offers patients a safe transition from the hospital to their home, as well as rides back to the hospital for scheduled check-ups and appointments. Through this partnership and new program, Cedars-Sinai became the nation’s first hospital system to integrate with CareKit’s platform. This is the first of many steps as HomeHero, in partnership with CareKit, continues to extend the healthcare system into the home.

CareKit 1.1: Care Card comes to the Apple Watch

You heard right. We released CareKit 1.1 today which includes two major updates to the Care Card: Apple Watch integration and 3D Touch.

With CareKit 1.1, the Care Card is now available on the Apple Watch. Extending the Care Card to the wrist just made adhering to care plans and marking completed care items on-the-go significantly easier. A new Care Plan complication on the Watch also lets users gauge their Care Plan completion throughout the day.

Care Card

Care Plan Complication

3D Touch is also now functional with the Care Card and Connect. Let users peek, pop and perform actions straight from the master screen. With Connect, you can even initiate FaceTime calls or other custom methods of communication. This added 3D touch enhancement seamlessly integrates with any iPhone that already uses 3D touch and will begin working automatically without any changes required from the development team.

For developers, adding the Care Card to Apple Watch could not be simpler. Drag and drop a folder for watch into your existing app build and a single line of code will immediately produce the companion watch app. Voila! It does not require a separate build, but rather is a “build one, get one” model. Build one iPhone app, get one watch app for free.

We are excited to see how you bring these features to life with the inspiring work you are doing. Download the new release and get started today.

One Drop + CareKit: Unlocking the Power of Data-Driven Self Care

At One Drop, we want everyone with diabetes to feel empowered by their everyday experience. We are transforming diabetes care by removing barriers to health data and providing support on-demand.

With CareKit, One Drop took data-driven self care to the next level. CareKit enhanced our platform by allowing users to set daily diabetes management goals and track their progress over time. CareKit also provided a way for users to instantly share data with their Care Team (e.g. family, friends, health care providers, One Drop Experts, etc.) for personalized feedback.

After just one month, CareKit showed its transformational potential. Specifically, CareKit demonstrated the power of self-motivation. Here's some data on users who set at least one daily diabetes management goal:

  • They became more engaged in their diabetes management.
    • 56% logged more data than they did before
  • Their blood glucose levels improved.
    • 40% spent more days with in-range average blood glucose values
    • 42% logged a greater number of in-range blood glucose values
  • They exercised more.
    • 35% increased the total number of minutes spent doing physical activity

All the data collected so far reinforces that we're headed in the right direction. This is the beginning of a major transformation in healthcare: data-driven self care. This is not just about diabetes; this is about all of us. We are building tools to empower everyone to take their health into their own hands.

We're in this together.

Iodine's medication information: Easy to integrate with CareKit

What does everyday life have to do with what happens in the doctor's office? At Iodine, we wrestle with that question, trying to help people capture their everyday experiences with medications and make that experience meaningful for themselves and their doctors alike. It turns out that’s the same challenge that CareKit is designed to address – and so when we heard about what Apple was cooking up with CareKit, we were thrilled to be part of it.

In particular, the Care Card and the Connect module help us tackle two challenges. Our Start app – for people starting a treatment for depression – lets people track their medication and their symptoms, working them towards a sense of success, or helping them get back to their doctor with meaningful information about their experience. This made the Connect module a natural fit; it allowed us to build a simple hand-off of a user's data (which we summarize into a progress report) to their clinician. Since most physicians still use fax machines, we built a way to send reports via fax (as well as via email).

The Care Card solved another problem for us, since it helps people track their medication usage and get important information about their medications. This was an opportunity to include some of the data that Iodine had created around what to expect with medications. Our team of pharmacists did extensive research to create clear and simple information about medications - when they might kick in, common side effects, benefits and risks, and the experiences of other people who've tried them. (Check out to see our philosophy of medication information in action.)

CareKit made it possible for us to elegantly integrate this data into our Start app, right in the context when our users might have a question about what they're taking.

And now we've created a JSON API for hundreds of the most commonly used drugs—from Adderall to Zoloft, and from Advil to Zantac - for other CareKit developers to use, free for direct-to-consumer use. Sign up for an API key at and read the Iodine API documentation for details on what the API offers and how to use it. Then let us know how our API is working for you!
