This is a question all app developers get asked, along with how much does web app development cost.

Web applications are growing their popularity every day. Developing web apps is a complex and rather long-term process where every detail is important as it differs your business from any other and makes it unique.

We’ve already covered some related question in our previous articles:

Nonetheless, we made a dedicated article for this question, because it’s very difficult to answer how many hours it will take to develop a web app at the early stages. The reason why it’s difficult to predict timing is that it very depends on answers what go into making a web app.

Apps are bespoke pieces of software, each different and individual. You get simple apps and complex apps. Some web apps can use a few functions and be a little different from a website. And some apps carry inside lots of functions, just like these web apps made with AngularJS.

You can ask us to build a web page that displays data or another one that access camera, GPS, support social media functions, and so on.

The average timing for development of web application

Yet, there are industry researches (100 development companies participating) and the humble experience that allows us to give you more specific numbers. On average it takes 4.5 months to build a front-end app and a backend infrastructure.

But here’s a more detailed breakdown, based on our experience.

information base, database back-end 2-3 months
social media, in-app purchase, logins, favorites, back-end admin panel 3-6 months
dedicated analytics, unique functionality, visual pattern 6< months

That said there are areas of the process to watch out for. Intricacies where time and budget for a web app can take far too much time and become costly. Like with all projects without proper planning and risk mitigation development can go on and on, resulting in a boogie low-quality app.

How much does it cost to develop a web app?

The final cost of your web development depends on the range of functions and features it will have. It can be a lost-lasting and complex process so it will take from 3 months and involve the efforts of a team of developers.

Here is the list of the potential need for your software solution that defines the cost of the development:

  • Variety & complexity of features and functions
  • Design features
  • Number of services a
  • Technology and frameworks
  • Development team experience, level of expertise, capabilities, location, & rates

For the start of building your web applications, you need to find and hire a team of experienced specialists. A crucial step is to build an appropriate business strategy for developing and promoting your solution. that’s a key to success.

How to save time and budget during web app development?

How Long Does It Take to Develop a Web App

It all starts with the requirement gathering phase of the Discovery phase. We recommend you this article it will help understand how to save your time negotiating with developers. If the requirements are noted down well you have the opportunity to prevent misunderstandings and future problems. It forms the basis of time estimation and costs. Poor requirements can lead to bad planning. Thus it may also affect the time required to write down detailed software specification requirements for the app. On top of that, please keep in mind all the changes that you make want to add to the development. Changes in the development mean changes after the code is written forcing developers to go back to their work, which has a large potential for introducing bugs.

More info about the cost of your own app development, read in our article on the blog.

In addition, we advocate for a thorough testing plan and QA practices. Proper testing practices are invaluable, they help find problems early, which saves a lot of time on the delivery phase. The ideal situation is to thoroughly test your web app and send detailed organized feedback to the development team.

Benefits of web apps

Web applications have a lot of benefits and become more and more popular. Read more about the advantages of web apps here below.

  • Access – you have access to any web app wherever you are and whenever you want, you can use for it any computer, mobile device, and browser or operating system, you just need to have the internet at your place. Web apps even open opportunities for remote full-time work.
  • Update – unlike desktop apps, web applications have an automatic update so you don’t have to do it on your own which saves time. 
  • Security – data on the web-based application is monitored by admins 24\7 and it is easier to detect unknown activity and detect what’s wrong. Also, as we know, the first step of any web app is registration, so if you get a notification that someone is trying to login to your account, you can always change the password, delete your data or contact a support team.
  • Integration – a big plus of developing the web app is that it is made specifically to your business, it meets all your requirements, it is a custom web application that includes elements of your brand, has specific functions of access to data relevant exactly for your business needs, so you don’t have to waste time and money for testing as it will be suitable for you anyway.
  • Technology – any core technologies can be used in the development of a web app, it mostly depends on the requirements of this application, there are three main languages – JavaScript, CSS, and HTML.

Examples of web applications

Web applications` popularity is growing every day. Many businesses are already integrated with them. We recommend you to take a look at the latest and successful web apps and specific options that they offer:

Google Drive

Google Drive remains one of the most popular and usable web apps all over the world. This is a place where you can store any documents you want and have access to it whenever you want. You can save online as well as offline files, add, change, or delete them. The registration process is pretty easy as you can do it via Gmail. It offers 5Gb of free storage and diverse types of documents – presentations, researches, photos, albums, etc.

Highrise Expeditors

The property management system is GBKSoft`s web app development that was created for property owners – Highrise Expeditors. It helps to manage your buildings, specifically resolve tenant complaints or violations from the side of owners. The user of this app gets access to the Property Management System after registration, and watch the status of their application. Business owners get reminders about any violations or other issues to solve them as quickly as possible. So this app helps to know every problem that appears in your property business and keep the reputations among tenants on a high level.


We’ve also worked with the construction company LEO that needed a web application for bringing their business to a new level. In detail, this company manufactures concrete materials for the construction industry made of cast stone that looks like natural limestone. This company has a small part in the whole building processes but they take care of their reputation. Our developers’ team created a web app that gathers and saves data about clients. Also, every client can register after making an order and check the status of the construction. As for the business owners, they now have database storage where they keep all quantities and calculations of stones not to lose anything. This app makes their work optimized, structured, accurate, and credible.

As you see there are many spheres left that need a web application to optimize, manage, and modernize the working processes of small and large businesses.


One more bright example is the travel business and the most popular web app Booking. After registration, all users get the ability to find any type of hotels and hostels if they plan a business or family trip. You can choose the right city, filter by prices, and check if there are any free rooms in the hotel you choose. Also, Booking selects the hotels the suitable prices for you on the date you have chosen. You can save any variant to “favorites” and make a decision later. Booking gathers and saves all information about their users – number, email, age, place of birth, work, number of family members, and pets. Also,  Booking reminds you about your reservations or savings on your email to hold the communication with users.

Top popular web development directions

Artificial Intelligence
Artificial intelligence imitates human intelligence and performs cognitive functions with the help of powerful computers. AI has the ability to learn, gather data, analyze it, understand emotions, and solve complex problems. Today we can see the appearance of chatbots or virtual assistants like Alexa, Siri, Cortana, which helps to involve more customers to the businesses and interact with them more individually. Implementing AI opens new opportunities for digital services for customers, consistency of chat, voice, messages, and websites.
JavaScript remains the most popular programming language during the past years. It continues to grow and improve its functions. We can see the appearance of new frameworks, libraries, and designs. These updates keep JavaScript in the first place. This programming language fits any type of os development as it is flexible, powerful, and innovative.
Progressive web applications
PWA is considered to be the most popular type of web development. The page loads are the same as in simple web pages but progressive websites have a wide range of powerful functions. Despite the speed of the internet and choice of browser, PWAs work perfectly fast and simple. PWAs provide excellent user experience without cache problems. Also, PWAs are secure as they work through HTTPS.
Single-page applications
SPA is Javascript-based applications that provide excellent work on customers` devices. The single-page application works quickly and easy in use as it loads only the required content of the page, not the whole page. This type of web development is suitable for adaptive websites, for support of mobile apps, applications for tablets, and computers.
Motion UI design
Motion UI is considered to be a trend because of its dynamic graphics, excellent animation, and influence on the convenience of app usage. This type of design provides a smooth transition to the user interface. Motion UI gives developers the ability to animate the content simply.


At the end of the day, all the best practices we’ve covered so far turn out to be worthless without good communication. Flawless and regular communication between all parties makes the project run smoothly.  It’s important to share the same vision and avoid misunderstandings. At GBKSOFT we strive for good planning and constant communication with our clients.  We do our best to explain every step of the development and suitable for your requirements. All it takes from you is to contact us and consider web app developed.

Take you time!

It depends on the complexity - from 2-3 months for a simple app, and from 6 and more months for more complicated.
JavaScript as a language for frontend with some framework like Angular CSS/HTML for styling animations and layouts, PHP as a language for backend with some framework like Yii2 or Laravel. Depends on application requirements.

I just completed a fully functioning web app in 3 weeks. It is an employee timekeeping app logs GPS location with each time punch. Then automatically correlates location with a client address. Has full employee user administration back-end and generates downloadable CSV files with the time keeping data for the Payroll department to use. They plan on adding more features down the road.

That makes sense that companies do estimations on certain projects. I bet it takes loads of QA measures to ensure a safe project. I’ll have to consider getting software updates for my computer apps.

For an experienced developer, you could get a prototype done in a few weeks. Without having programming knowledge, it would take much longer. You would need to be familiar with Objective-C and Apple’s development tools for iOS, or with web development tools and using a system like PhoneGap. The apps themselves are pretty simple- they connect to a back-end web service, send it authentication, and ask for pictures. The harder part is doing the back-end work of storing the pictures and doing the account authentication, especially doing it in such a way that you could easily scale up to millions of users. Modern cloud systems like Microsoft Azure and Amazon Web Services certainly make this easier, but it still takes a lot of know-how to get it right.
