An application specifically designed to run on smartphones and tablets. Like pocket-sized tools that you can use anywhere.
Instagram, Uber, and WhatsApp are mobile apps that let you share photos, get rides, and send messages from your phone.
A mobile app is an end-user application (iOS/Android), not a single cloud service. Cloud providers offer supporting services for mobile apps—such as authentication, databases, storage, APIs, push notifications, analytics, and CI/CD—but there is no one-to-one “Mobile App” service across AWS, Azure, Google Cloud, or OCI.
