Native Mobile App

A hybrid app is a type of mobile application that combines elements of both native and web apps. It is built using web technologies like HTML, CSS, and JavaScript, but is wrapped in a native container that allows it to be installed from app stores and access device-specific features like push notifications, camera, and GPS.

Flutter is a freely available framework developed by Google that enables the creation of cross-platform applications that are natively compiled using a single codebase. Using Dart – a Flutter coding language, Flutter facilitates the development of applications for both Android and iOS devices.

App size refers to the amount of storage space a mobile application occupies, measured at different stages of its lifecycle from download to active use. Understanding and managing app size is crucial for mobile developers because it directly impacts user acquisition, retention, and overall app performance. App size encompasses multiple dimensions including download size (compressed data transferred from app stores), install size (uncompressed data after installation), and storage size (total space used during active use including caches and user data).

An In-app purchases SDK (Software Development Kit) is a set of tools, code libraries, and documentation provided by a developer platform, such as Apple or Google, that allows app developers to integrate the ability for users to make purchases within their app.

Developers can use Apple's StoreKit framework to incorporate in-app purchases (IAPs) into their apps on iOS, macOS, watchOS, and tvOS. The framework facilitates secure payment processing on behalf of the app, connecting with the AppStore and requesting user authorization for payments.
