Health (Apple)

Health (Apple) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Health (Apple) rather than just read about it. In short: Health is a health informatics mobile app, announced by Apple on June 2, 2014, at its Worldwide Developers Conference (WWDC). The app is available on iPhone and iPod Touch devices running iOS 8 or later, and on iPads running iPadOS 17 or later.

Key takeaways

  • Health (Apple) belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Health (Apple) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Health (Apple) from memory before moving on to harder problems.

Reference excerpt

Health is a health informatics mobile app, announced by Apple on June 2, 2014, at its Worldwide Developers Conference (WWDC). The app is available on iPhone and iPod Touch devices running iOS 8 or later, and on iPads running iPadOS 17 or later. The application collects health data such as blood pressure measurement and glucose levels, but also collects physical tracking data such as step counts. It can pull data from fitness trackers, smartwatches, smart scales, and other devices.

Features The Health app tracks and stores various health data and metrics, as well as clinical medical records for users with supported health insurers or hospitals signed up to the "Apple Health Records" program. Data is divided into several categories: activity, body measurements, cycle tracking, hearing, heart, medications, mental wellbeing, mobility, nutrition, respiratory, sleep, symptoms, vitals, and other data. Users with a connected Apple Watch will have their health information from the device automatically imported into the health app including their activity rings, walking and running distances, flights climbed, mindfulness minutes, sleep analysis, handwashing metrics, environmental noise levels, heart rate, blood oxygen levels, and ECG measurements. Health data can also be logged manually or through third-party applications. Since iOS 13, Health has been capable of period and fertility tracking, allowing users to log their menstruation cycles and receive predictions as to when their next period may begin. With iOS 16, Apple introduced medication logging, which allows users to track the medicines they are taking and set reminders for when to take them, as well as alerting users of potential drug interactions. Both features are also available as standalone applications on watchOS devices. With iOS 17, users can also journal their daily emotions and moods in order to track their mental health, as well as take standardized anxiety and depression tests, which can be useful in knowing if it’s an appropriate time to consult a therapist. "Medical ID" profiles are also kept within the Health app, which allows for key medical information to be easily accessed by first responders without the need to unlock someone's device. Users can choose to what to display in their Medical ID, such as allergies, medications, blood type, organ donor status, and emergency contact details. As of July 2016, users on iOS 10 or later in the United States have been able to sign up to be an organ, eye, and tissue donor through the Health app. Initially, the Health app was criticized for its lack of compatible third-party applications (at its release on September 17, 2014, along with iOS 8), glucose tracking, proper health data explanations, and sluggish app performance. Eventually, Apple fixed these issues with software updates. In 2019, the Health app received a redesign as part of iOS 13, which simplified navigation of the app by replacing the dashboard with a summary tab and placing everything else under a "browse" tab, similar to the previous "health data" tab.

Electronic Health Records In 2018, Apple's "Health Records" was introduced, which allowed on iOS 11.3 or later for users to import their medical records from their doctor or hospital. On June 6, 2019, Northern Louisiana Medical Center announced an early partnership with Apple to allow clinical medical records shared through the app. Shortly after Apple began allowing compatible electronic health records (EHR) to self-register for the "Health Records" project. Other partnerships in 2019 included University of Tennessee Medical Center in Knoxville, Medical Center of South Arkansas; Northwest Health of Springdale, Arkansas; Blessing Health System of Quincy, Illinois; Doylestown Health of Pennsylvania; Franciscan Health; Bayhealth Medical Center of Dover, Delaware, and the Department of Veterans Affairs.

HealthKit API

HealthKit is the accompanying developer application programming interface (API) included in the iOS SDK (Software Development Kit) for the Mac. It is used by software developers to design applications that have extensibility and that can interact with the health and fitness applications on iOS. After the release of iOS 8 on September 17, 2014, Apple removed all HealthKit-compatible apps from its App Store to fix a bug that caused cellular and Touch ID issues, and then re-released Healthkit, with the release of iOS 8.0.2, on September 26, 2014. As of February 2017, several manufacturers other than Apple sold hardware that was HealthKit enabled.

ResearchKit & CareKit APIs

ResearchKit and CareKit are two other health-related software frameworks which Apple have introduced to further build upon the capabilities of HealthKit, allowing software developers to create applications for gathering medical research and following care plans, respectively. Both APIs can interact with the health application and facilitate the sharing of health information between patients and doctors. Apple has also introduced a standalone research application for iOS and watchOS devices, which allows users to volunteer and participate in long-term research studies run by Apple and various health partners.

Employees In July 2018, Apple hired cardiologist Alexis Beatty, while working on the Apple Watch and Health integration. David Smoley, former chief information officer of pharmaceutical company AstraZeneca, was hired as a Vice President of Apple in June 2019. In October 2019, former Columbia University Medical Center cardiologist David Tsay joined Apple Health.

Worked examples

Example 1 — a first encounter with Health (Apple)

Start with the simplest possible case. Write down what Health (Apple) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Health (Apple) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Health (Apple) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Health (Apple)

In research
Health (Apple) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Health (Apple) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Health (Apple) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fitness apps, Health software, IOS-based software made by Apple Inc., so understanding it makes those chapters shorter.
In everyday life
Look for Health (Apple) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
