An operating-system-specific programming language, such as Objective C for iOS or Java for Android. A react native mobile app has a high level of consistency and performance. They can also make use of the phone's functionality, such as the camera and address book. It may also use a variety of applications without being connected to the internet. However, because it is tied to a particular operating system, such an application is expensive to construct, necessitating the developer to create multiple copies that work on several platforms.

Companies looking to promote themselves to the smartphone market have the following possibilities in addition to native mobile apps:

Hybrid App: An app like this is cross-platform compatible while yet enabling access to the hardware on the phone. It was built using Sencha, PhoneGap, and Mosync, among other platforms.

Dedicated Web App: A website that is optimized for use on mobile devices. These are made for a specific platform and will not work on other phones, including those with built-in cameras.

Generic Mobile App: This is a mobile webpage that works on any smartphone.
