MyFitnessPal

MyFitnessPal 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 MyFitnessPal rather than just read about it. In short: MyFitnessPal is a health and fitness tracking smartphone app and website. The app is available for Android and iOS devices.

Key takeaways

MyFitnessPal 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 MyFitnessPal to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of MyFitnessPal from memory before moving on to harder problems.

Reference excerpt

MyFitnessPal is a health and fitness tracking smartphone app and website. The app is available for Android and iOS devices.

Overview The app allows users to identify the nutritional value of particular food or drink items, track their dietary intake and calorie and macronutrient goals, create personalized meal plans, and track exercise activity. According to the company, specific tools and content are available for users taking GLP-1 medications. According to the company, as of 2026 the app has 280 million users and is available in over 120 countries.

History Released in September 2005, MyFitnessPal was developed by Mike Lee, with his brother Albert Lee later joining him to launch the app and the company. On February 4, 2015, MyFitnessPal was acquired by athletic apparel maker, Under Armour, in a deal worth $475 million. On May 4, 2015, MyFitnessPal introduced a premium subscription tier for its applications. In January 2017, founders Albert Lee and Mike Lee departed from the company to pursue other business ventures. On October 30, 2020, Under Armour announced that MyFitnessPal would be sold to the private equity firm Francisco Partners for $345 million.

Security breach On March 29, 2018, Under Armour disclosed a data breach of 150 million accounts at its subsidiary, MyFitnessPal. The compromised data consisted of usernames, e-mail addresses, and hashed passwords, but not credit card numbers or government identifiers (social security numbers, national identification numbers). Under Armour was notified of the breach ten to four days before the disclosure and learned that the leak happened sometime in February.

Worked examples

Example 1 — a first encounter with MyFitnessPal

Start with the simplest possible case. Write down what MyFitnessPal 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 MyFitnessPal 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 MyFitnessPal 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 MyFitnessPal

In research: MyFitnessPal 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 MyFitnessPal 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: MyFitnessPal is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2005 software, 2015 mergers and acquisitions, 2020 mergers and acquisitions, so understanding it makes those chapters shorter.
In everyday life: Look for MyFitnessPal 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.
