What Determines App Development Costs?

The overall app creation cost mainly hinges on the software goal and the time required to code it. In fact, plenty of factors influence how much you need to spend on development. Here are some of them:

Factors that influence app development cost


The more complex app you want to create, the higher its development cost. Ensure the quality of the interactive and advanced features to excel the product’s performance. Decide if you need an application programming interface (API) to integrate with other services or a content management system (CMS).


The number of platforms to place the app on impacts the total cost. For instance, native app development for a single operating system (OS) will be cheaper than a cross-platform one. Nevertheless, it’ll be unprofitable. If you choose Android app development, you lose potential iOS device users. And vice versa.


The more, the merrier! And also more costly. The main factors that define the price are skills and experience. Junior, middle, and senior developers will ask for different fees. Keep in mind that the amount of people involved in the application development and their experience influences the quality of the final product and the date of its release.


Post-release development is as crucial as the pre-launching one. You must ensure the application works smoothly without glitches, crashes, or other issues. The total price of building an app worldwide, including the United Kingdom, already includes the mobile app maintenance cost. The support lasts for a specific time after launch, an average of 6 months.

How Application Scale Influences Development Costs

App scalability means its potential to handle many users and effectively maintain interactions with them. Users want an impeccably working solution that works without problems. The absence of adequate scalability will cost not only money but the entire reputation of your business.

The scale of the application deals with its database, back-end, and servers. The wider your target audience is, the more scalable your platform has to be.

The complex multifunctional application related to social media, entertainment, or news could cost over £100,000. Developing a niche and simple app in the UK with minimal features might cost less than £20,000. Next, we’ll show examples of different platforms and their average prices.

A good old social media application for sharing media, kind of like Instagram or Facebook, doesn’t sound like a wild challenge. Yet, it’s essential to consider all the functionalities you want to add that would make it valuable and innovative. The cost of app development in the UK starts at £40,000 and might reach up to £300,000.

To create something like TikTok, be ready to spend a fortune on obtaining music licenses and integrating numerous services and features for more engagement. Such an app creation cost in the UK starts at £130,000.

How about an on-demand app like Uber or Uber Eats? Those require the creation of separate modules for restaurants, clients, drivers, and managers. The total cost of creating an app in the UK might vary from £65,000 to £400,000.

Let’s overview an online dating app. Rather than a niche platform, an application like Tinder won’t require more than previously listed. The approximate cost of its development is between £20,000 and £50,000.

App Development Options

There are five common ways to create an application:

Develop an app yourself

Developing an app on your own requires significant technical skill and expertise.

You can create an app from scratch if you are well-versed in programming languages, front-end and back-end frameworks, databases, cloud solutions, etc. However, if you are not an experienced developer, you will likely need to invest considerable time and effort to learn the necessary skills.

Additionally, it can be risky, as you may encounter issues and errors that require professional assistance. If you are considering developing an app independently, assess your technical abilities and determine whether it is viable.

There are numerous free resources to learn how to develop apps. For example, Codecademy, Udacity, Coursera, edX, YouTube channels (The Net Ninja, CodeWithChris), Apple Developer Documentation, Android Developer Documentation, and others.

Hire a freelancer

Hiring a freelancer can be an attractive option for small businesses and startups. It allows you to develop an app without committing to the overhead of hiring a full-time employee.

Freelancers offer flexible schedules and can work remotely, but you should verify their credentials and experience. Look for specialists with a proven track record of building high-quality apps, and don’t forget to learn reviews and ratings from past clients.

Freelancers may provide guidance and support throughout the development process, making it easier to navigate potential roadblocks.

There are many platforms where you can find freelancers for app creation. The most popular options include Upwork, Freelancer, Fiverr, Toptal, and Guru.

Partner with a development company

Hiring a software development company can be a reliable and efficient way to create a cutting-edge app. Vendors employ teams of experienced coders and designers working together due to a well-organized workflow and security standards.

Additionally, IT companies typically have access to the latest tools, ensuring your app will use the most advanced technology stack.

When selecting an app development company, check its reputation and read testimonials. Look for a company with an experience similar to your specific needs and schedule an initial consultation to discuss your project requirements.

Customize an app template

Buying a pre-designed app template is another cost-effective option. They are often available online and can be customized to suit your specific needs.

However, you should understand that buying a template may result in a less unique or customized app, as your competitors can also use the same example. Additionally, customizing may be challenging and time-consuming if you are unfamiliar with app development.

You can use these resources for purchasing pre-designed app templates: CodeCanyon, TemplateMonster, Instamobile, Sketch App Sources, and Codester.

Build with a constructor

App builder products are designed to simplify the development process for non-technical users. These products often offer drag-and-drop interfaces and pre-built components. This way, you can easily create a basic app without any coding knowledge.

However, app builders may be limited in customization and functionality and unsuitable for complex or sophisticated solutions. If you consider using this option, carefully evaluate your needs and ensure that the product you choose is capable of meeting them.

Examples of app builder platforms include AppyPie, BuildFire, Bubble, Zoho Creator, AppSheet, and others.

Approximate App Developers Cost in the UK

How much does it cost to make an app in the UK? The development team is pivotal in the total sum you invest in the project. And much depends on the specialists’ experience:

Junior developers

Industry newbies, aka junior developers, with a year of experience as a maximum, is one of the first options. They are no strangers to Javascript and frameworks like React, Vue, Angular, or Svelte. Also, juniors can develop back-end development using Javascript/Java/Typescript/C# and might even know the Agile methodologies. 

The cost to build an app in the UK with the help of junior developers is up to £35,000 per year.

Mid-level developers

Mid-level specialists cover a more comprehensive range of skills. They have experience developing applications for different operating systems and working with cross-platform technologies. Mid-level developers build, test, release and deploy apps on the market. With up to 4 years of experience, they know how to develop cloud-native solutions and work with databases like MongoDB, MySQL, PostgreSQL, etc. 

As a result, creating a moderate app with mid-level developers will cost you £50,000 per year.

Senior developers

As great old-timers, senior developers know what they do. By choosing them, you get a strategic plan for the development process. Seniors will provide you with bespoke app architecture design and codebase and excellent problem-solving skills. They know how to work with cloud services like AWS, GCP, and Microsoft Azure. 

As a bonus, seniors can lead the dev team and provide exceptional final product quality. To build a complex app with advanced functionality, you’ll need a minimum of £200,000.

App Marketing Costs

The cost of marketing an app can vary widely depending on several factors, such as the size and scope of your marketing campaign, the target audience, and the app’s niche. The essential costs include the following:

App store optimization (ASO)

ASO involves optimizing your app’s metadata, such as its title, description, and keywords, to improve its visibility in app store search results. It is typically a one-time cost that depends on the complexity of your app and the level of optimization required.

App install campaigns

App install campaigns focus on driving installs. They include ads on social media platforms, mobile ad networks, and other channels. The amount charged varies with the platform, targeting options, and the competition level in your niche.

Influencer marketing

Influencer marketing means partnering with social media influencers or other content creators to promote your app to their followers. It can effectively reach a highly targeted audience, and its price varies due to the influencer’s reach and engagement.

Public relations (PR)

PR is about building relationships with journalists, bloggers, and other media outlets to generate buzz and credibility for your app. However, it requires a significant investment of time and resources.


Retargeting covers showing ads to users who have already downloaded or interacted with your app. This way, you can re-engage users and encourage them to use it more frequently.

Here’s a table that summarizes the approximate cost ranges for each of the app marketing strategies:

Marketing Strategy

Approximate Cost Range 

App Store Optimization (ASO)

£500 – £5,000

App Install Campaigns

£0.50 – £5 per install

Influencer Marketing

£500 – £10,000 per campaign

Public Relations (PR)

£1,000 – £10,000 per month


£0.20 – £1 per click

We used data from sources such as Business of Apps, Mobile App Daily, and others.

Ongoing Costs of App Maintenance

The ongoing costs for maintaining an app can vary depending on the app type and features, the development team size, and the infrastructure it runs on. They include the following.

Server hosting costs

The cost of hosting the app on a server is determined by the hosting provider, the server type, and the app size. Cloud-based hosting options like Amazon Web Services (AWS), Google Cloud Platform, and Microsoft Azure offer scalable solutions that can grow with the app’s usage.

Development costs

Even after launch, an app may require regular updates and bug fixes from experienced developers. You should have a maintenance plan to ensure your software is up-to-date and functioning correctly.

Content and data costs

Some apps require regular updates to their content, including product listings, pricing information, or user data changes. So, you will need ongoing expenses, such as paying for access to data feeds or hiring a team to manage content.

Third-party services costs

Many apps rely on third-party services for features like push notifications, in-app messaging, and analytics. They may demand continuous subscription or usage-based fees, which can increase over time.

Security and compliance costs

As the app evolves, it should meet new security and compliance standards. It includes regular security audits, compliance reviews, and regular monitoring of user data.

Customer support costs

Providing ongoing customer support can be costly, especially if the app has a large user base. Remember about maintaining a help desk, providing live chat support, or offering phone support.

We prepared a table with estimated average costs for maintaining an app, broken down by category:


Estimated Average Cost (per year)

Server Hosting Costs

£2,000 – £5,000

Development Costs

£10,000 – £50,000

Content and Data Costs

£1,000 – £5,000

Third-Party Services Costs

£5,000 – £10,000

Security and Compliance Costs

£2,000 – £5,000

Customer Support Costs

£1,000 – £5,000

Costs of Publishing an App on the App Store and Google Play Store

Publishing an app on the App Store and Google Play Store involves certain costs that developers should be aware of:

Developer account

Both platforms require developers to have an account to publish an app. There is a one-time registration fee for Google Play Store and an annual fee for App Store.

In-App purchases and subscriptions

In-app purchases and subscriptions on the App Store and Google Play Store generate revenue, but the platforms also charge a commission fee for these transactions. You should consider these expenses when setting the prices to guarantee app profitability.

And here are the fees for App Store and Google Play Store:

Cost Item

1. You make less than $1M (£720,000) in annual app revenue; 

2. You’re after 12 months of service in the App Store with a subscription-based app. 

15% for the first $1M (£720,000) of earnings you make each year.

Once the total earnings exceed $1M (£720,000), the service fee is 30% for the rest of the year.

How to Choose an App Development Company

Choosing an app development company is an important decision that can significantly impact your success. Here are some factors to consider:


Check the company’s portfolio to see the types of apps they have already created. Ensure developers have experience working in your industry and understand its unique challenges and requirements.


Ask if the company has expertise in the specific technology stack required to develop your app. For example, this is what Inoxoft uses to create mobile solutions:

  • Cloud Infrastructure: AWS, Azure, Google Cloud
  • Programming languages: Java, Kotlin (Android), Swift, Objective-C (iOS), Python
  • Backend frameworks: Node.js, Ruby on Rails, .NET, Django
  • Front-end frameworks: React Native, Flutter, HTML, CSS, JavaScript

Cooperation model

Experienced vendors can offer you several models of cooperation. For example, with Inoxoft, you can create applications using:

  • Remote developers — a flexible option where you pay for the time and materials and can change or add requirements
  • Dedicated team — a solution with a monthly salary where developers work on the whole project from start to finish
  • Extended team — a staff augmentation service with a fixed price defined by the contract before the start of cooperation

If you are not sure which model is suitable for your specific needs, please contact our team.


Communication is critical for successful app development. Pay attention to the company’s availability, response time, project status updates, progress reports, and honesty about any issues or challenges.


Ensure the development vendor you choose has expertise in building secure apps. The company should use encryption, secure data storage, and communication protocols and comply with GDPR, HIPAA, and PCI-DSS regulations.

Support and maintenance

Ask the company about their post-development support and maintenance services to keep your app up-to-date and stable functioning.


Price is essential but not the only factor. Be cautious of companies that offer low amounts, as they may sacrifice quality or cut corners to reduce costs. Look for a vendor that offers a fair budget that aligns with the value they provide.

Equine Registration Platform for Tracking Racehorses’ Welfare

Our client faced the problem of poor equine state management. The idea was to create an application allowing all parties to record and access information about racehorses’ health and training.

We have developed a solution supporting seven user roles, including equine owners, trainers, veterinarians, etc. It allowed them to add important information, download media files, view the activity calendar, and leave comments on the animal’s profile. And the owner got the ability to hire professional horse care providers and pay for the services directly in the app.

The solution helped make racehorse management transparent, improve animal welfare, and connect owners with service providers.

Voice-Powered Web and Mobile Cloud-Based Solution for AI System

Beyond Verbal Company is a startup that recognizes emotions and diseases using voice intonations. With a health and emotion monitoring algorithm, the company needed a platform to collect patient data and create a voice database. The ultimate goal was to improve AI predictions for the diagnosis of cardiovascular diseases.

While developing a web platform for doctors and a mobile application for patients, we faced some challenges. The interface had to be equally convenient for all types of users, and the solution itself had to increase the accuracy of voice analysis and comply with HIPAA regulations.

As a result, we have created a secure and intuitive cloud solution. It allowed doctors to manage patients, launch surveys and work with recordings, increasing the accuracy of voice analysis and the diagnosis relevance.

Round-the-Clock Insurance Agent

We were approached by a company dealing with employee health insurance. They needed a solution that would allow each insured employee of the enterprise to be informed about the service’s details. It was essential to provide instant access to a personal insurance plan with a quick search for the necessary data.

As a result, we created an application, allowing each employee to view personal health insurance conditions, limits, and lists of hospitals and specialists. Users can also quickly contact an insurance agent for additional information.

Final Thoughts

The cost of developing a mobile application is influenced by many factors, including its complexity, platform, team size, and experience level. Also, you should consider the launch expenses on the App Store or Google Play Store, maintenance costs, and marketing fees.
