The mobile app market is growing at a rapid rate. In fact, according to studies, mobile applications will yield over $935 billion in revenue by 2023. Besides, in the past few years, we have seen a surge in the number of people who use their phones and tablets to access the internet and perform various tasks. 

This trend is only set to continue. That is why businesses should have a presence on mobile devices. It also presents a great opportunity for business houses to reach new customers. To add to that, our app development company in Kolkata delivers mobile solutions that assure you great user engagement and expand your market base.

Being a business owner, you would always like to stay connected with your customers on a personal level. And these days, that means being on their mobile phones. App development is one of the most effective ways to reach and engage your customers. Here are ten reasons why you should leverage app services from a mobile app developer company in India for your business:

  1. Apps are where your customers are: Mobile apps are indeed where your customers are. In fact, studies show that people spend more time on apps than they do on the internet. Besides, more and more people use mobile devices as their primary way of accessing the internet. That’s why it’s vital to focus on application development.
  2. The best tool to keep your customers: There’s no denying that apps are the best tool to retain your customers. By providing a convenient, easy-to-use experience that is accessible at any time, apps make it simple for customers to stay engaged with your brand. In addition, apps can be customized for individual users, which makes each person feel valued and appreciated. All of these factors come together to create a powerful tool for retention. However, to make sure that your app gives your users an enjoyable experience, you need to seek the help of the best Android, hybrid and iOS app development company in Kolkata.
  3. Better accessibility for your customers: With an app, customers can quickly and easily find the information or services they need without having to search through a website. That can be a great time saver, and it can also lead to increased customer satisfaction. In addition, apps can be designed to work offline, which is a vital consideration for businesses with customers in areas with poor or no internet coverage.
  4. Customer service: An application can be a great way to improve your customer service. You can use it to send notifications about special sales or events, answer customer questions, and provide other information that would be useful to your customers. Also, applications offer businesses a direct line of communication with their customers. That is a huge benefit when it concerns providing customer service and support.
  5. Enable easy shopping: An application can make it easy for your customers to shop with you, whether they’re looking for something specific or just browsing. That way, you can also increase the sales and revenue of your business with apps. Also, collaborating with one of the top-rated 10 mobile app development companies in Kolkata, India will ensure that you get an app that provides users with immersive experiences and get them converted instantly into paying customers.
  6. Applications can help businesses save money: They can do this by reducing print and advertising costs and increasing efficiency and productivity. It can also help improve your overall marketing since this is a great way to expand your customer base and reach new people at a minimal cost.
  7. Gain a better understanding of the tastes of your audience: While there are many reasons to focus on application development for your business, one of the most important is the availability of customer insights. With it, you can collect data on how your customers use your product or service, what they like and don’t like, and what their overall experience is. That information can be used to improve your business and customer experience by developing targeted marketing campaigns and personalized offers.
  8. Boost consumer engagement: Applications offer a variety of features and benefits that can help businesses boost consumer engagement. These include the ability to offer personalized content, a seamless, interactive, and convenient user experience, and the ability to collect data that can be used to improve the app and the overall customer experience. Moreover, merely developing an app for a single platform won’t be able to engage customers on all levels. If your app is for Android devices, then potential buyers using Apple devices will be missing out on great opportunities. Thus, get connected with an eminent iOS app development company in Kolkata, India or someone that develops apps for the platforms.
  9. Helps build brand awareness and recognition: A mobile app is a powerful tool as it can help build brand awareness and recognition. You can significantly increase your visibility and reach by creating a branded app and making it available to your target audience. In addition, a mobile app can help to solidify your brand identity and make it more memorable to your users. By investing in a mobile app, you can reap the benefits of increased brand awareness and recognition.
  10. Additional convenience for your audience: A mobile app can be additionally convenient for your audience by providing them with a way to access your content on the go. That is especially important for audiences who are always on the go and need to be able to access your content quickly and easily. A mobile app can also offer push notifications. That can keep your audience up-to-date with new content or special offers.

In conclusion, you should start focusing on building mobile apps and we, as an affordable and high-quality mobile app development company in Kolkata, India. Mobile apps are convenient, portable, and easy to use. It is also a great way to reach a larger audience.

The app market shows a growing trend. Any company that wants to expand its business should not miss this trend. Creating a mobile application has many advantages. But it is also essential to take into account a few steps during its development to achieve the most profitability.

The eight essential steps below will help you develop a successful mobile application that meets your customers’ needs and helps achieve your business goals. Hence, consider hiring a reputed iOS and android mobile app development company in Kolkata, India that follows these steps, and you’ll be well on your way to developing a great mobile app!

  • Understand your market: When developing it, you must understand your market. That means understanding who your target audience is, what are the needs of your target audience, and what your application can do to solve those needs. Without this understanding, creating it will be very challenging to create a successful app.
  • Specify your target audience and idea for it: Before you even start developing it, you must specify your target audience and be clear about what your application will be about. Trying to build it without this clarity is likely to fail. Your target audience will largely dictate what kind you develop, what features it will have, and how successful it ultimately is. So take the time to point out who you want to target and what things would interest them before you begin developing it. Besides, outsourcing to an experienced app development company in India will give you complete peace of mind on this matter. Because they would first figure out your audience and then start working on the design and development.
  • Choose whether it will be native, hybrid, or web-based: The type you develop will impact the overall experience for your users. As such, when you want to create a fast, responsive, and reliable app, native is the way to go. A hybrid is a good option if you want to develop an app quickly and inexpensively. Webgen Technologies has highly skilled hybrid app developers to help you out. Also, they can support you with website design and development of web-based apps. The web is the way to go if you want to create a more complex app with many features. No matter what kind of app you’re looking to build, deciding on the right type is an essential step you can’t miss.
  • Weigh your options for monetization: When developing your application, you need to think about how you will monetize it. There are many choices available to you. And you need to weigh the pros and cons of each one to decide which is best for it. You can charge for downloads, sell in-app purchases, or show ads. However, each of these has its advantages and disadvantages. So you must carefully consider your application and your audience before decision-making. As a professional android and iOS app development company, we can suggest some best ways to increase your earnings through apps.
  • Create your marketing strategy: An application marketing strategy is essential when developing it. It will help you to define your target audience, set your goals, and create a plan for how to reach those goals. Without a marketing strategy, it will be challenging to make it successful. You increase your chances of success in the mobile app market by building a comprehensive marketing strategy.
  • Strategize how you would optimize it for the app store: If you want to ensure that your application is successful, you need to take the time to strategize and optimize it for the app store. That includes keyword research, considering the competition, and creating a well-designed and user-friendly UX. By taking these steps, you can give it the best chance for success. A capable mobile app development company in Kolkata, India can help you with this definitely.
  • Identify and use your resources: When developing a mobile app, you can’t afford to miss any essential steps. One of the most important steps is to specify and utilize your resources wisely. You can easily spend too much time and money developing it without getting the desired results if you’re not careful. To avoid this, you must take the time to identify all the resources you’ll need to develop it successfully. That includes things like market research, software development tools, and, of course, human resources. Once you have all your resources in place, with confidence, you can begin developing them, knowing that you have everything you need to succeed. Seems complicated? Not to worry! We have got you covered. Connect with the best mobile app development company in India to create a world-class app for your brand.
  • Make it secure for your business and users: As the number of mobile applications has increased, so have the instances of data breaches and security issues. If you are developing it for your business, you must take security measures to protect it and your users’ data. Many things can help make it more secure, such as ensuring that all data is encrypted, using secure authentication methods, and providing a mechanism for reporting security issues. By taking these steps, you can help keep your and your users’ data safe.

When developing a mobile application, there are eight essential steps you cannot miss and a mobile app development agency will always follow them in order to build an app that connects with audiences effectively. These steps include research, planning, monetizing, strategizing for marketing, and more. Each step is crucial to its success.

Mobile applications are all the rage these days, and there’s no denying their popularity or utility. For businesses, having an application can be a game-changer as per reach, engagement, and conversions. And, this has caused an increase in demand for mobile app development company services. But before you can reap the benefits of it, you need to make sure that it is developed on a solid foundation – and that’s where mobile application architecture comes in. 

In simple terms, it is the process of designing and planning the structure of a mobile app. That includes everything from the user interface to the backend systems. It is the set of rules, systems, and processes that govern the development, deployment, and management of applications. 

It is vital to get the architecture right from the start because it will have a notable impact on the development process, the performance of the application, and its overall success. 

In fact, it is a crucial factor to consider when developing an application for your business because it can impact the cost, quality, and speed of development. 

If you want to develop it for your business, you must understand the different types and platforms for it. You can choose to develop for android devices or iOS devices or both. For this reason, you need to reach out to an android and iOS app development company in Kolkata, India. Hiring from India will reduce the cost of developing your app to a great extent. You should also know the benefits and drawbacks of each. Here are a few points to help you learn more about application architecture and how it can impact your business!

What factors to consider while choosing it?

The choice of application architecture is a complex decision that must weigh various factors, including its nature, the target devices, performance requirements, and more. Some of them are stated below:

  • Consider its nature: Is it a simple app with limited functionality, or is it a complex application with many features? The answer to this question will help you determine which type of architecture is best suited for it.
  • Consider the target devices: What type of devices do you want them to run on? Different architectures are better suited for different device types. 
  • Consider the type of business you’re in: This will determine the type of it you need. For example, if you’re in a retail business, you’ll need it to handle vast traffic and data. If you’re in a simple trade, you might be able to get away with a less complex architecture.
  • Consider your budget: It can be expensive, so you’ll need to ensure you have the funds to invest in the correct type of architecture. Webgen Technologies is one such agency that offers affordable packages for mobile app development in India. We have customized pricing structures to fit our client’s budgets. 
  • Consider your team and skill set: Not all architects are created equal, so you’ll need to find someone with the right skill set to build what you need.

Different types of it: 

Applications come in all shapes, sizes, and unique architecture. The most common types of architectures are native, web, and hybrid. It’s always better to consult with a good app development firm in India, to understand which architecture will suit your needs best. No one is better than them in explaining the reasons behind choosing a particular architecture.

Native apps are built specifically for a certain operating system, such as iOS or Android. These are usually more responsive and perform better than web or hybrid applications.

Web applications are those that are accessible through a web browser. These apps are usually less responsive and have poorer performance than native apps.

Hybrid apps are those built using a combination of web and native technologies. These usually perform better than web applications but are not as good as native apps. For hybrid apps, you can always count Webgen Technologies as your reliable hybrid app development company.

Advantages of using it correctly:

There are several advantages to using the proper architecture. 

  • The most vital advantage is that it can help to ensure that your application is scalable and reliable. 
  • When well-designed, it can make it easier to add new features and functionality to your app and to ensure that existing features continue to work well as your app grows. 
  • Additionally, good architecture can help make your app more efficient, both in terms of processing power and battery usage. 
  • Finally, when it’s well-designed, it can help to make your app more secure by making it more difficult for hackers to exploit vulnerabilities.

Is there a risk of performance issues while using the wrong application architecture?

There is always a risk of performance issues when using it wrong. When incorrect, it can lead to problems with the application itself and with the devices it is used on. Incompatible architectures can also cause data loss or corruption. In fact, it can lead to bottlenecks and data duplication, which can impact performance. Also, this can make it difficult to scale the app as needed. That can also lead to performance issues. Therefore, leveraging the services of one of the top mobile app development companies in India will ensure that nothing goes wrong during the process of app creation.

How to choose the correct mobile app architecture for my business?

Since there are so many different types to choose from, sometimes it becomes hard to decide which one is right for your business. But, you can consider some key factors that will help you choose the most appropriate architecture for your needs.

  • Consider the scale of your business: If you have a large firm, you’ll need it to handle a lot of users and vast data. But, if you have a small business, you might not need as much scalability.
  • Consider data security: If you’re handling sensitive data, you’ll need it to be secure and compliant with all the necessary regulations. And, for an app development company, the data security of you and your users is the utmost priority.
  • Consider what type of functionality you need: Do you need a simple app with a few basic features? Or do you need a complex app with many advanced features? 
  • Consider what type of devices your customers use: Do they use iPhones, Android phones, or both? 
  • Consider what operating system your customers use: Do they use iOS, Android, or both? 

In conclusion, there are many advantages to using the correct mobile app architecture. It can save you time and money, and it can improve the performance of your app. A professional developer of a renowned app development company in Kolkata, India will always consider the above-mentioned factors carefully before deciding on the architecture. This ensures that the final app delivers flawless performance to its users.

Some popular technologies we use for app development include native tools for developing, such as Xcode for iOS applications or Android Studio for Android apps, and cross-platform development tools like React Native or Flutter.

  • Sketch out a rough idea of the application’s functionality and UI.
  • Research and select the best platform (iOS, Android, etc.) and development tools for the job.
  • Begin coding the app, starting with the essential features and working towards the more peripheral ones.
  • Test it frequently on actual mobile devices to ensure that it is functioning as intended.
  • Launch the application to the public and continue to monitor its performance, making changes and additions as necessary.

There is no definitive answer to this question, as the cost can vary greatly depending on the specific needs and requirements of the client.

With the advent of new technologies, the business landscape is rapidly changing. A large part of this change is due to the growing importance of mobile apps. Businesses need to have a strong presence in the mobile sphere.

But with so many companies that develop apps, how do you select the top one for your business?

Here are a few factors to consider when making your decision:

  • Consider your needs: There are many development firms. And so are the case studies, blog posts, articles, etc., written about selecting the best one for your business needs. Even though all of that is useful, we believe that the first step towards finding the top app development firm for your business starts with taking a closer look at your own firm and understanding your needs.
  • Portfolio of previous work: The quality of a company’s past work is one of the best indicators of the quality of its future work. It will give you a good idea of their quality of work and will help you understand whether they’re a good fit for your project. Of course, the portfolio is just one factor when selecting companies that develop apps. Other factors include its experience and customer service. But the portfolio is a great place to start your search for the correct development partner.
  • Experience in developing apps: You should look for a firm that has experience developing apps for businesses like yours. 
  • Also helps in Digital Marketing: We have a team of professional marketers who can help you with your App marketing so that everyone comes to know about it.

The additional questions to consider include before outsourcing to a mobile app development company in Kolkata.

-How long has the agency been in business?

-What kind of experience do they have with developing mobile apps?

-Do they have a good track record of successful projects?

  • Understanding of your business’s needs: The best development companies have a deep understanding of the needs of businesses in various industries. That is because they know what features and functionality are most important to these businesses. They can therefore tailor their apps to meet these needs. That means firms can save time and money by having an app specifically designed for them. They do not have to depend on the generic one. It will also not meet their specific needs. This understanding is vital in determining which firm is best for your business.
  • The platforms they specialize in: You should go to an android app development company in India if you want to launch an app for android devices only. Different companies may have various areas of expertise, so it is crucial to find one that specializes in the platform you are interested in. That will ensure that your chosen firm has the knowledge and experience necessary to create a successful app.
  • Look at the reviews and ratings: It is crucial to look at reviews and ratings to select the top firm. That will give you an idea of the quality of work it produces and its level of customer service. Checking out reviews and ratings is a great way to ensure you select the best firm for your app needs. The top mobile application development companies in India will have positive reviews and ratings from their past clients.
  • Ability to provide creative solutions: A firm that can think outside the box and comes up with innovative solutions is likely to be a top-notch developer. If a firm has a portfolio of well-designed and popular apps, that is another good indicator that they are a top app development service provider. Do your research and take your time in selecting a firm, and you will be sure to find the best mobile app development company for your needs.
  • The company’s transparency and communication style: A firm that is open and honest about its process and prices is more likely to be a reputable company that will deliver a high-quality product. A company that has good communication and is responsive to your questions is also more likely to be a company that will offer a good product.

There are many factors to consider when selecting an android or iOS app development company in Kolkata, India.  The most important factor is probably its experience and track record.

On one hand, Java and Kotlin are considered the top popular languages for Android app development. On the other hand, Swift is every developer’s preferred choice of programming language for iOS apps. Here is a list of all the languages that our developers are proficient in and use most for building apps. 

For Android:


Java – It is the most used programming language supported by Google and is utilized for creating robust and high-level applications. 


Kotlin – It is open-source and easy to understand and comes with best-in-class features.

C# – It is a high-level language integrated with the .NET framework and offers a vast library with a range of pre-defined functions. 


C++ – Developers can use this language using the Android Native Development Kit (ANDK) for the implementation of various components of the app in C++ native code. 


For iOS applications:


Swift – iOS apps are superior quality apps with high-level functionalities and Swift is the appropriate programming language for iOS app developers. 


Flutter – Launched by Google in 2017, Flutter offers several advantages to developers like a collection of ready-to-go widgets, flexibility in implementation, and less coding. 


Objective C – It is derived from the open-source general-purpose programming language C and C++ and is now high in demand because it is simple to use and offers great run time. 


React Native – It is the most common programming language for hybrid applications and so app developers using React Native for creating iOS apps can also deploy them on the Android platform.
