A measurement and diagnostic tool application is a web, mobile, or desktop application that enables users to monitor their own health and fitness. Measurement and diagnostic tools typically provide interfaces for tracking diet, exercise habits, symptoms, medication intake, sleep patterns, moods, blood pressure levels, heart rate, weight loss goals and much more. Most measurement apps also track the user's location (via GPS) for reporting purposes.

Measurement apps are part of a larger group of applications used for personal health and wellness. Other related app types include fitness apps, weight loss apps, and sleep tracking apps. Most measurement apps do not share features with other types of consumer finance apps.

A measurement app can grow rapidly by showing users the value of the data that they are collecting. It's common for new measurement apps to provide visualizations and other ways of displaying the collected data so that users can quickly understand how they're currently using a certain product or service. It's also common for measurement apps to offer users rewards in exchange for sharing their data with the company. This gives users a sense of accomplishment while simultaneously providing valuable insights about how the product is actually being used in real life.

A measurement app faces a variety of legal, logistical, and reputational risks associated with the collection and storage of sensitive user information. Measurement apps should take measures to verify user identities to prevent identity theft and other forms of data compromise. It is recommended that measurement apps provide users with strong privacy controls and should only collect information necessary for the service to work.
