Whether you are going to hire a mobile app development company to create a desired solution or you want to start your journey as a software developer, this guide will help you to get details about the best programming languages. Let’s dive in-

What Are Programming Languages?


Programming language can be said an approach used by developers or programmers to write instructions followed by computers, smartphones, tablets, etc. Programming languages comprise a set of rules permitting string values 0 and 1 to be changed into different ways of machine code generation. Basically, programs are set of instructions written in specific languages including C, C++, Python, Java, etc. to complete a particular task.

There are two main categories of programming languages, let’s get to know about them

  • Low-level
  • High-level

A. Low-level

Low-level programming languages are difficult for humans to read and are closer to binary or machine code. These types of programming languages give little or no abstraction from a PC’s instruction set architecture. The benefit provided by low-level language includes that it is easy and fast to use and enables specific control over the functioning of the computer.

B. High-level

Unlike low-level programming languages, high-level programming languages are closer to the way humans communicate. These languages prefer to use words such as an object, run, order, class, request, etc. that are similar to the words we use regularly. Mobile app development companies use high-level programming languages more than low-level programming languages because these are easier to program. However, these languages take time to convert into machine code for the computer.

Different Types of Mobile Apps

While knowing about the best programming languages to create apps, it is preferable to know what are the different types of mobile applications. Various types of mobile apps demand different programming languages; hence, businesses need to hire mobile app developers who have expertise in various top languages along with experience.

The following are the types of mobile apps

  • Native Mobile Apps
  • Web Apps
  • Hybrid Mobile Apps
  • Cross-platform Mobile Apps

1. Native Mobile Apps

The native mobile apps are developed specifically for one platform and OS. These apps can be accessed by a particular segment of audiences and are also written using top app development languages for native platforms.

native app programming language

If you are going for Android OS, then hire android app developers who are experts in C, Kotlin, Java, etc. but if you are going for iOS OS then hire iOS app developers who are experts in Objective-C or Swift. When businesses are going to create an app from scratch, they must know that native apps perform better and have a good speed than other apps.  

2. Web Apps

Mobile Web apps or Web apps can be accessed by users via an internet browser window. The best part is the app doesn’t require any additional installation process or storage space and is available in different screen sizes. A web app can be used on any device easily as it is more responsive and functional while performing similarly to a native app. The major difference between both is native apps can work in both online and offline modes, whereas web apps can’t work in offline mode, they need an active internet connection to work.


Also, web apps don’t require to be updated as they get updated automatically on the web-hosted servers. The best programming languages to develop apps for the web are Dart, JavaScript, etc.

3. Hybrid Mobile Apps

Hybrid apps can be called the best combination of both native and web apps. They run via web browsers but can be installed on devices as well. However, these apps are not as reliable and fast as native apps, but they do have a higher capacity to manage the development process.


Hybrid app development facilitates businesses to not create and maintain separate apps for different platforms. It is the best way to save both resources and time while delivering good content to users. To create hybrid apps, there must hire dedicated developers with expertise in languages like Angular, JavaScript, CSS, HTML, etc.

4. Cross-platform Mobile Apps

Cross-platform mobile applications are developed for different platforms such as Android, iOS, Windows, etc. using a single code base. There are various cross platform app development frameworks and technologies as well that are used in cross-platform mobile app development.

cross platform apps

Programming languages used in creating cross-platform apps are C, JavaScript, HTML, CSS, etc. The cross-platform mobile app enables you to write reusable and shareable code to create apps for different operating systems. Due to less code, there is consumed less time in mobile app testing along with saving time and resources.

Tips to Pick the Best Mobile App Development Languages

At the time of choosing tech stack for mobile app development, picking up the best programming language is always a tough task. There must be technologies according to the type of mobile applications, to fit with the latest trends, and more.

Let’s get to know some considerable tips while selecting the suitable mobile app development languages

  • App Types
  • Time to Market
  • Scalability & Performance
  • Maintainability
  • Offered Security

1. App Types

Every type of application requires a different tech stack in order to perform better. Be it a mobile app, web app, embedded firmware, or anything else, choosing programming languages largely depend on what type of app you are going to build. General programming languages that can be used for development are objective-C, Python, JavaScript, Java, C#, etc. Among all these, you can choose languages according to the web or mobile app development trends as well.    

2. Time to Market

While introducing any new technology or program to your team, always ask yourself, is it the right time to do so? If it is possible, always try to leverage the existing skill set so that there can be less time to market. Try to work with a smaller code to make the solution fast to market.

If there is sufficient library support, modules, or packages, then, there is no need to create everything from the scratch or follow a mobile application development guide as these will make your work easier and will save development time as well.

3. Scalability & Performance

How your app will perform, this question immensely depends on the programming languages you select. It is much more considerable when the existing development environment doesn’t allow you much scope for scaling. Hence, to bring out the best performance of your app, you have to use suitable programming languages.

It will also include how many users your built app can manage and what will happen if there are a large number of users in the future. Popular tech stack to ensure the scalability and performance of the app is LAMP, .NET, Ruby on Rails (RoR), Java Spring, and MEAN.  

4. Maintainability

While using web or mobile app development best practices, technologies, or languages, developers also get huge support from the libraries along with their vendor support. To be sure about the tech stack, you need to look at the latest trends and update the release cycle as these are necessary for app maintainability. At the time of application development, businesses always think about higher user engagement for the long term and there can be situations when they will have to shift the code base to another development team.

If there is any particular technology you are working on for your app, then, you will need internal android or iOS app developers for hire and will have to pay for the maintenance cost as well. This cost will get affected by the obtainability and expertise of the developers in your specific area.

For instance, Java development services and C# developers can be hired easily in the Midwest area in comparison to Python, Ruby, and PHP developers. It indicates that you must think about the app’s long-time existence and easy maintenance while picking up suitable programming languages.       

5. Offered Security

Security is the most demanded feature in any type of app. So, when you are going to choose appropriate programming languages, consider that every app has different security requirements. Security makes the app more robust and protects the app users’ data from online hacking and cyber threats.

Developers need to follow specific security guidelines for different applications. For example, to develop healthcare-related apps, they must follow HIPAA compliance and for finance apps, they must follow PCI compliance.
