    Our app development process follows agile principles allowing us to remain flexible while focusing on rapid app development. We ensure you are involved where appropriate and updated at all times.
    When you’re set on working with our team on your app development, we’ll first arrange a discovery call with you. We want to learn all about your vision for the app and the reasons behind building it. Equipped with this information we can go away and start researching and gathering data that will help us formulate a strategy.
    The app development team assigned to your project gets together, bringing in with them pre-researched solutions and ideas. This allows for our brainstorming sessions to be both creative and constructive, keeping the focus on creating clear goals and strategies. By analysing your business and the industry you’re in, as well as welcoming your contributions we uncover profitable insights and convert them into strategic pathways for success.
    With a fully scoped out project and a solid plan of how we’re going to get there, our designers begin to translate those ideas into screen mockups, all the while keeping UX top of mind. The attractive and on-brand UI is then merged with the backend code, bringing the app to life.
    As new parts of the app get built, we continue to test everything and remove any bugs we may come across. Our quality assurance processes include various scenarios to ensure everything is up to scratch for you and your users. The beta release of the app creates new opportunities to gather feedback as clients and consumers alike may provide us with invaluable observations.
    Once your app is live on the Apple and Android app stores, we’re still right here in your corner. We’re committed to helping you grow by offering ongoing support and maintenance whilst also having the flexibility to add new features as and when you should want them. As a digital marketing agency, as well as an app development company, we can help you promote the app, too.


    At Web Design London we believe that if you’re going to invest in an app, it needs to be done right. Our extensive experience as an app development company means we know exactly what elements make a successful app and apply them intelligently creating seamless experiences that attract more app users.

    Building a native iOS app exposes you to large numbers of users. Statistics show that the Apple iOS market share continues to dominate in the UK, with more than 50% of total mobile users remaining loyal to Apple. As the rapid move to digital continues, it’s becoming more paramount to use technologies such as mobile applications to allow users around the world to interact with your brand and for you to stay on top of their minds every time they glance at their phones. A robust app created by our experienced team of app developers allows you to connect with your customers 24/7 by utilising push notifications. No need to spam their inbox anymore!
    Our team capabilities do not end on iOS builds - as a professional app development company we deliver apps with an even wider reach by using technologies that allow us to deploy them to Google Play Store and make them accessible to Android users. Our comprehensive Android app development skills allow us to create unified UX across the two platforms, winning you more downloads on both. While building apps for both platforms may sometimes add complexity, you can rest assured that your project is in good hands. With the vast knowledge of the different platform-specific guidelines and requirements and the collaborative, agile approach we take, we leave virtually no room for errors.
    Great mobile app design goes far beyond the visual aspect. It is the combination of the different user experience (UX) principles, wrapped together in a beautiful user interface (UI). When our talented team of UX and UI designers come together they combine research, user behaviour analysis and design principles to produce usable, intuitive and desirable products that your target audience simply cannot resist. Just like any step in our mobile app development process, each design decision is a deliberate one, adding to its attractiveness and as a result, increasing your download rate.
    Successful mobile apps are ones that either solve a problem or serve a specific purpose for the users. Our team is committed to guiding you through the mobile app development process without losing sight of this overarching goal, which is to build a useful and valuable app that is going to impact lives. Our experience shows us that the ROI potential of an app that offers a positive user experience is much greater than that of the apps that don’t directly respond to users’ needs. Let Web Design London be your app development company and guide your mobile app build to success.

    I approached GLO for a rebrand, website re-design and SEO package. Right from the start I felt like a priority. The way the team look after their clients is top notch and the culture runs through the entire organisation, there wasn’t any idea or extra request that wasn’t met with enthusiasm and I was always kept informed of where the project was at.

    The quality of the website and brand that they have created for us is great. The website is beautiful and already ranking on first page Google searches, after less than a week! I could not recommend John and his team highly enough, and I can see us working with them for many years to come.

    GLO were introduced to me with a glowing recommendation by a close friend who had recently enlisted their services. I was extremely impressed with the work that they had completed on his behalf and as I happened to be in the market for a complete overhaul of my company brand and online presence, it was a no brainer to get in touch.

    From the outset John, Mark, Beth and the whole team were amazing. From discovery stage, defining a clear roadmap, impeccable copy, a complete redesign of the brand and all things in between, GLO took the lead and produced an end product that exceeded all expectations. I look forward to working with them again very soon on another rebrand.

    I could not be happier with the results. I strongly recommend that anyone in market for their services get in touch right away.

      App Development FAQ’s

      What makes a good app UI?

      App UI refers to the user interface, or in other words, the way the app looks and feels. There are a few fundamental principles that designers should follow in order to achieve a good app UI. The aim is to create interfaces that are pleasurable and easy to use and this can be achieved by making the navigation intuitive and user friendly. Keeping the UI simple and avoiding too much clutter with unnecessary buttons or text can also improve your mobile app UI. Ideally, the designer should aim to only allow for 1-2 actions per screen. The placement and size of the buttons are equally important - the tap target should be within the thumb zone and large enough for each user to tap easily. All of the above, amongst other considerations, such as whitespace, typography, colours or language are important aspects of the mobile app UI and should be determined based on the target audience. Using user personas and customer journey maps informs you who you are designing the product for.

      What app maintenance do you offer?

      Here at Web Design London, we are committed to bringing your app development to life by combining the extensive experience of our team and our agile approach to project management. However, our support does not stop post-launch. We want to help you grow and support your business. Our app maintenance service ensures that when we are there for you should anything go wrong post-launch. We can be your technical team when you’re experiencing any server issues or have users report to you crash incidents.
      Equally, we are here to ensure that when you are ready to add new features to your app and grow it, you have the right team in your corner.

      How can a mobile app make me money?

      There are different ways in which a mobile app can make you money. The monetisation aspect of your app should be something that you think about early on, ideally before beginning the development process, as the different ways to make money from an app may influence the way it’s built. There are about six different monetisation models that you may observe. These are; paid apps, subscription apps, in-app purchases, app advertising, affiliate marketing and mixed monetization methods. To choose the right monetisation model for your app, consider what type of app it is. For example, many gaming apps make money off in-app purchases. On the other hand, apps that offer software as a service often work on a subscription basis. Each of these models comes with positives and negatives and should be considered individually.

      Can you create an app without coding?

      Yes, it is possible to create an app without coding. Several platforms offer app building without having to inject your code. The features are pre-made and can be put together to create an app of your own. Some of the platforms available include the following: Andromo, AppsGeyser, AppMakr, GameSalad, Appy Pie, Appery and Swiftic.

      Using any of these platforms to build your app is a much cheaper and quicker process. However, there are many limitations to this process. You are limited to only using the features that have been pre-built in the platform, which may not give you the results you are after, and may therefore not produce an app that stands out from others. Additionally, creating an app on your own means a lot of trial and error, especially when it comes to uploading it to the app stores and following their comprehensive and specific guidelines.

      What is application design and development?

      Application design and development are two stages of the mobile app development process. These are the stages of the app development process where first the screens are designed and then the mobile app comes to life by bringing in the frontend code and backend code together during the development stage. The design stage usually comes after UX research and analysis. This allows for the UI designs to be focused on the target audience and offers a great user experience to those users. Once the designs are done, they are translated into code which builds the application and connects it to the database. The application design and development stages often merge at some point and might be revisited as quality assurance continues throughout the development stage.

      Why rapid application development?

      Rapid application development is an agile development approach that focuses more on the ongoing development and user feedback rather than on sticking to a strict plan. The typical rapid application development (RAD) process starts by defining a loose set of requirements. This takes away the need for costly planning. Once the developers know the rough plan for the application and understand the requirements they start working on a prototype to have something to show to the client and users. When the prototype is presented, the developers collect feedback and make amendments. This loop of improving the prototype and gathering feedback may happen a few times until the product meets the needs of the users. Once that point is reached, the product can be finalised. This approach usually results in faster delivery of the product that meets the client’s requirements. Additionally, it has the potential to be a more cost-effective development process as the team will only focus on building the features the client needs rather than adding standard features that may never be used. It also keeps the development team motivated as with the frequent input from the client and their involvement, the developers’ efforts may be acknowledged on a more frequent basis.

      What is mobile app development?

      Mobile app development is a series of processes and procedures required to build software for small, wireless computing devices, such as smartphones and other hand-held devices. When compared to web applications, mobile apps are written in a way that specifically takes advantage of the unique features of the mobile device. This could include a gaming app utilising iPhone’s accelerometer or a health app utilising a smart watch’s temperature sensor. The main mobile app platforms are iOS from Apple and Android from Google.

      In the past, each of these platforms required separate code to be written for the different devices. This was referred to as native mobile app development. Nowadays, it is more common to use coding languages that build apps that can work across different platforms and operating systems.

      How much does mobile app development cost?

      Mobile app development cost varies depending on the way you choose to develop the app and its intended use. If you require a simple app for your business, opting in for no-code builders, such as Appy Pie, Appery or BuildFire could be a good option. These have pre-coded elements that can be used in your app meaning there is no need for hiring app developers who have extensive experience in coding. Slightly higher on the price level are tools, such as Amazon’s HoneyCode which also allow anyone to build an app by dragging and dropping elements using an interface. These often work on a monthly subscription basis. At the top of the range sit the more complex apps that require native app development due to the sophisticated features they include, such as artificial intelligence or 3D elements. The cost of developing an app like that could be as high as £200,000.

      How is a mobile app developed?

      Mobile app development begins with setting up the foundations. Once the idea for the app is there and the team members are clear on who the product is being made for, the developers can begin setting up the storage solutions, databases, APIs and servers for the backend of your app. While the designs are being prepared, it is important to set up developer accounts for the app stores you plan to upload your app to. This step can sometimes take several days to complete so it’s best to do it early on. With the designs and the backend set up in place, the coding and programming phase can begin. When the frontend interface is connected with the backend code, it is time to begin the testing phase. This needs to be done continuously as it allows to catch any bugs before launching the app.

      Once you feel the app is ready to be pushed to the live environment and presented to the users, it is a good idea to contact a digital marketing team or perform your own research to find the optimal keywords and descriptions to optimise your app for the app search engine results. Before launching, you will also need to make sure you have a website promoting your app and that it meets the requirements of the app stores. Continue with your promotional efforts and set a specific date for the launch to build up momentum. Your app developers will take care of submitting the app to the app stores in good time to allow for the approval period and any last-minute fixes that need to be done. Once launched, the app should be tested again to ensure no code went missing when moving from development to live environment, which could lead to bugs or crashes.

      How do you deploy an app?

      Mobile app deployment is the process of installing, configuring and enabling a specific application to a URL on a server. This is typically done via an application manager or software management system. Once the process of deploying an application has been completed, it becomes publicly available on the URL. Depending on the version of the app you are trying to make visible, you will be deploying it to different platforms. On Apple devices, when building an app, it is a common practice to first deploy the app to a platform called TestFlight. This is where the app that is still being developed can be stored and accessed by beta users. This is used throughout the testing phase of the mobile app development process and gives the developers time to fix any technical issues. Once the app is ready to be shared with the public, the app would be deployed to the Apple App Store and the Google Play Store.
