What does a web app development company do?
The providers discussed in our review are a real guide to the world of tools that allow a business not only to strengthen its presence on the Internet and bring the user closer to its service or product but also to optimize many processes, which will ultimately lead to increased income. A web app development agency performs a number of functions:
- Activity planning (collecting requirements and specifications from the client),
- Designing a future product (choosing the right technologies and frameworks, developing an interface),
- Testing (checking functionality, performance and security),
- Deployment (debugging and fixing errors, launching on a server or cloud platform),
- Follow-up support (updating and servicing in accordance with user feedback).
And at each of these stages, the professionalism of the web development companies in the UK brings bonuses to the client, which will subsequently increase the efficiency of work. To do this, it is necessary that the best web app development companies organically combine technical and flexible skills to successfully fulfill its role.
After all, time is money and even if engineers are virtuoso in the main languages and have excellent knowledge of frameworks and libraries but do not have the skills of teamwork or their communication is uncomfortable for the client, cooperation will not bring the expected results so you will draw your budget.
But with a successful combination of all aspects, such companies productively create diverse and exciting projects, constantly developing and mastering new technologies. That is why their products have a high potential for reaching and benefiting millions of users around the world.
Criteria of a leading web app development agency
According to DataReportal, 96,2% of all Internet users browse the web within their mobile devices, so investing in creating web applications is essential for businesses that want to stay competitive and attract more potential leads in this cut-throat industry.
In this part of our review, we want to tell you what makes a web app developer the best and what you should pay attention to when choosing the right partner. And if we know you well enough, you want to work only with the best.
- Reputation in the market. If after a short analysis you can see that the provider has a lot of positive reviews and recommendations from customers — then it’s Bingo! Moreover, by studying this indicator, you will get an understanding of the company’s workflow, its ability to overcome difficulties, professionalism, etc.
- Level of services and customer support. If you need constant server updates, security scanning, backup monitoring and you do not want to stay up at night learning all this alone — ongoing or post-launch support is crucial. Staying updated after the initial results are achieved is extremely important, do not rest after the fanfare of success, because you can sleep through the moment when competitors are on your heels.
- Team composition. Make sure that web application development company has a fixed team of developers, analysts, UX researchers and project managers. This way you won’t find yourself in a situation where your brilliant idea requires an urgent search for talent that needs to be poached from another company.
- Increased security. Providers, who are second to none, contribute the highest level of security and offer solutions with the maximum data protection. This mainly concerns the security of the data that you store in your application, such as personal information of clients, payment data, etc. And today, everyone has become extremely careful not to miss anything.
- Social responsibility. Mindless consumption does not correlate with a responsible attitude to work — and you want to find someone who will become a reliable partner, right? Corporate social responsibility means the implementation of environmentally friendly, ethical business practices, diversity of talent and other important points.
Now that you know what makes app development companies in the UK the top leaders in the market, we can discuss in more detail how the selection process looks and works. The goal of our overview is to give actionable tools so that you can find the perfect match with a contractor in a matter of days.

Also, in the descriptions of projects, you can often read customer reviews.
- Request a short brief. Most likely, after the previous steps, you will have a number of questions about custom web application development that the company can answer directly. Usually, representatives of providers are willing to make contact and clarify those points that are important for a preliminary assessment of the possibility of cooperation.
- Initial consultation. Meeting with the crew is practically an admission that you are potentially interested in collaborating with these specialists, and they want to look for new solutions for your task.

So, all the stages have been completed and you are almost there. Next, you will only have to dive into the intricacies of the world of web applications, which, under the guidance of experienced engineers, can very well become an exciting adventure with amazing results.
The cost of hiring web application development companies
Several studies say, the average salary of a developer in the US is $79,753 per year. But don’t think that customers who want to get an application will only pay for the efforts of this specialist. There are quite a few factors that influence the final cost of the work.
Since most of our readers are not specialists in the field of web app development services, they do not know what exactly in their idea can significantly increase the final cost. To avoid unpleasant surprises, we offer a small summary that will allow you to roughly imagine the figures of the future application.
| Factors | Impact on the project cost |
| Functionality level | If you want a standard product with a basic set of functions, it will be cheaper due to low time costs and the involvement of lower-skilled specialists. The more complex and unique the format, the higher the level of training of developers. |
| Tech stack | Using trendy or complex technologies will increase the budget because web and app development companies with certain skills require high payment, and some licenses will add numbers to the final bill. |
| Scope and deadlines | The larger the project, the longer it takes to develop. With an hourly payment system you understand that the price cannot be low for large products. |
| Variability of services | Contractors can offer related services that look like a package. If you don’t need them, don’t spend extra money, but if you are interested, this option is a great opportunity to save your budget. |
| Team location | Office placement in large cities and metropolitan areas is directly related to the cost of an hour of work. At the same time, local small website application development companies can be much cheaper, and offshore vendors are in no way inferior in quality, but are pleasantly surprised with their price. |
As you can see, it will be possible to accurately calculate the app development cost only after a direct discussion with specialists, but now you are able to estimate the minimum project sizes of the providers you are interested in and the rate of an hour of work of their developers.
