mobile-application-development-4-programming-languages With the changing demands of the industry, the demand for skilled professionals in these languages ​​is changing. Programming languages ​​are changing and evolving at the same time.

As we’ve mentioned earlier, there are over 700 programming languages in the world. You might wonder why are there so many languages just to code? Because people keep creating them!

Some languages suit better to carry out certain tasks than others. For example, if you want to develop games, it’s advisable to go for Python, DarkBASIC, etc. If you opt for business applications, C, C++, Java, etc. is your go-to.

That being said, here are the four best programming languages and frameworks for mobile application development.

Flutter

mobile-application-development-flutter-logo-1

Initial release: 2017

What?

Currently, the most popular cross-platform alternative to React Native (jump down) is Flutter, a relatively new mobile application framework developed by Google. Developed based on the Dart programming language, Flutter takes a different approach to implement cross-platform features.

At InApps Technology, we strive to be at the forefront of emerging technologies, proudly to possess a sizable talented pool of Flutter engineers.

Due to being quite new, the Flutter community is rather smaller than React Native. However, developed to minimize previous setbacks, Flutter can provide fantastic performance and a native look to the apps developed with the support of the framework.

In other words, Flutter combines the ease of development with native performance while maintaining visual consistency across platforms.

Why Flutter for mobile application development?

  • Develop your application faster than the standard native application
  • App Maintenance Is Easy Thanks to Simultaneous Android and iOS Updates
  • Flutter’s “hot reload” makes it possible to make changes to the code and see the results immediately
  • Reduce Code Development Time
  • Increase Time-to-Market Speed
  • Suitable for any target platform
  • Minimize the risks and losses for your business

Based on the response, Facebook’s JavaScript library, React Native makes the user border. Instead of aiming at the web browser, it targets the mobile platform. When it comes to mobile application development, React Native is considered to be the best framework for both iOS and Android.

To put it in a different saying, JavaScript language allows you to create one single app that can run on different platforms instead of creating separate apps for each system.

Thanks to this approach, companies can build faster and much cheaper applications for iOS and Android users.

Where to Hire a Mobile Application Development Team

Freelancers, remote employees, or IT outsourcing vendors? It’s a good question as it depends.

Firstly, we’ll explain more about each type of mobile application development team. Next, to get you started, we’ll put them in comparison to help you get a better look. Lastly, we’ll provide a list of different websites for you to consider.

Freelancers 

mobile-app-development-freelancers

If you have a relatively small project that doesn’t need a mobile application development team (from designers to testers), then a freelance developer can do just enough.

InTalents, Upwork or Freelancer are popular platforms for hiring mobile application developers. These platforms act as liaisons between employers and freelancers, processing payments and ensuring optimal protection for both parties in case of potential cyber fraud.

Pros of choosing freelancers:

  • Often the most cost-efficient way to gain access to a worldwide base of knowledge and skills.
  • Fewer responsibilities as an employer; once the project is delivered, the working relationship is either ended or paused until you collaborate on some project in the future.

Cons of choosing freelance developers:

  • The managerial overhead of keeping track of multiple tasks done by separate contractors.
  • Potential data security threats when allowing complete outsiders access to your confidential data.
  • They are less personally invested in the long-term success of your endeavor because of the temporary nature of their employment contract.

Remote employees

mobile-app-development-remote-teams

In case you have medium to long-term projects that need specific training, consider a remote employee for your mobile application development project.

A remote employee is somewhat more like an addition to your team, rather than an independent player like a freelancer. There are many places to find and hire a mobile app developer by yourself.

For example, LinkedIn is a good source. However, you’ll need to spend more time separating candidates who are not open to work or those looking for office-based positions.

As an alternative, you can opt for these options.

YouTeam connects individual developers from agencies and clients. All agencies and developers have to pass a thorough screening process. They will be banned if their skills differ from what they advertise. If you need a remote team of developers, YouTeam is a nice option.

Another example is Remote.com, a popular platform searching for full-time and part-time remote contractors worldwide. Remote lets you either look for candidates manually or let the AI algorithm find the best talent based on the information you provide like project duration, skills, and the payment model.

Pros of remote teams:

  • You form productive and engaged teams ready for a long-term commitment.
  • Employees working remotely often cost less, as they don’t require office expenses and other benefits.

Cons of remote teams:

  • Hiring and forming teams from remote employees take significant time.
  • Corresponding parts of your project can be halted if they fall ill, go on vacation, or simply quit.
  • Correctly estimating their performance and productivity can be very challenging.

Outsourcing companies and agencies 

mobile-app-development-outsourcing-teams

When you’re having a complex project or the need for future easy scale-up, a software outsourcing agency is your best choice. With this approach, you can hire top-notch mobile application developers having practical experience.

Added to that, it also ensures deadline commitment, quality may be exceeding your expectations, and management headaches won’t be yours to bother.

There are many firms offering this kind of service. While each has its own strengths, there is just a number that is suitable for you and your business goals.

For instance, companies like InApps Technology put great emphasis on being transparent and commitment to clients from all phases of the project. Working towards a long-term vision, the company strives to be a reliable companion rather than just an outsourcing vendor.

If you are worried about getting your money’s worth, InApps Technology offers pay-as-you-go. In other words, in case you don’t enjoy working with them in phase 1, you can easily move on to other more suitable vendors.

InApps Technology offers mobile app developers for hire, UI/UX designers, business analysts, project managers, QA experts, etc. Having provided 200+ effective solutions, we are proud to be listed as Top 1 software development company in Vietnam and Top 5 in Southeast Asia, according to Clutch and GoodFirms.

Pros of outsourcing:

  • Access to ready teams having the needed expertise.
  • Innovative solutions to minimize time-to-value for your projects.
  • The technology vendor takes care of the team’s motivation, perks, benefits, and replacement if need be.
  • Data confidentiality thanks to best practices.
  • Time and resource

Cons of outsourcing:

  • You might experience few management complexities but controllable.
  • Cultural differences may initially be a challenge but can improve over time.
