Application concept & roadmap
There are always many ideas and ways to go. Our app development agency will help you choose the right way. We will prioritize the app backlog together and create a roadmap.
Application design & prototype
In this stage, the concept is becoming a reality. Our app designers and app developers will create an interactive prototype of the future mobile app and prepare handover for developers.
App development process
We only have the best app developers in our agency. From front-end to back-end, we use the latest technology for mobile app development. We can help with native and hybrid mobile development.
User testing of the app
There is nothing more valuable to any business than feedback. That is why user testing is always a part of our app development process. Quality control is an essential part of our process.
Management & quality control
Let's be agile and lean as possible and tailor the app development to your needs. We use Prince 2 Agile methodology to ensure the app is delivered on time and in the best quality.
Support the app after launch
We do not only deliver the app. The mobile app development process is only the first step on our journey. We are here for you to support your operations and develop the app further.

Mobile app for a Czech beverage maker
We have used the latest technology in mobile app development to deliver this AR/VR game for a summer Campaign of Kofola, a prominent Czech beverage maker.
The app which was developed in Unity was a great hit with hundreds of thousands of downloads in just a few months.
The client was happy with the cooperation, and we continue to work on future improvements on the app. Several updates were launched during the first months of the campaign to futher improve the app performance.
"We are delighted with the result, user reviews are great. With Pixelfield we continue to develop the application and are already working together on other new projects.“

To launch a successful product
you need a perfect process
app development agency london discovery
Stage 1: Discovery
The first step of every project we work on an app development agency is discovery. It is a process, which is essential for the mobile app to be successful.
Together we gather all the information and materials we need for our designers and developers to start working on the project and we also discuss all parts, where a problem could arise during the development.
Only after this, we are able to set project roles and a timetable, which will be suitable both for you and us.
Discovery stage
mobile app development technology
Stage 2: Design & prototyping
Next phase, preceding app development itself, is UX and design. And our app design agency is here to help!
In order for a mobile app to be favoured by its users, it needs to have a smart and likeable design that is going to intensify the connection of your mobile app to your brand.
While creating the design, we always closely cooperate with our clients, as their feedback is just as important as anything else we do.
Alpha & prototyping

Stage 3: Development
Finally, when it comes to coding the app, we use all the experience, our mobile app developers have gained from our 7 years long experience as an app development agency in London.
We use an agile approach, which offers flexibility and adjustments to the project’s needs. We always share each and every update with the client, just as we test it with our dedicated testers.
After we finish with the app development, we can upload it to Google Play and App Store, if desired.
Development stage
The end?

We know how hard saying goodbye can be - and we hate to do it. Instead, we are always happy to work on future updates. Or we can just talk about how much your customers love the app. Or we can just talk about the weather.

app development before start
Before we start
You are probably wondering about the cost of mobile app development, right? It is very hard to tell you the price of mobile app development, as our London agency is focused on bespoke app development, where each app is an original. The price is always reliant on what features you wish to have in your app.
The factors we take into consideration while preparing an offer are:
design needs,
compatibility (is it an app for both Android and iOS or just one them?),
app’s complexity - the more features, the more time we spend on development,
future updates and app’s extensions.
We are able to establish the price after we receive a specification for your project.
mobile app development progress
No obstacle can stop us
We love all kind of challenges. Whatever your app needs, we are ready to come up with a solution, that will make your dreams come true. The possibilities are endless. We can create an app using AR, we can implement a chatbot into the app, connect the app to other software you are using, or we can even create different versions of the app for different devices.
why app development agency
Why should you go with a mobile app development agency like us?
We are a bunch of people, whose minds are full of extraordinary ideas and extensive knowledge, we are always happy to use while working on your app ideas.
We will not tell you that our app developers or app designers are the best in London. We believe that actions speak louder than words. Give us a call and see for yourself whether or not we are the best fit for your mobile app development project.
How we manage mobile app development projects
We love to be agile while working on mobile app development, but on the other hand we understand that we can’t let the project loose and wait how everything is going to turn out. That is why we combine agile and classic project management.

Pros and cons of agile development
We practice Prince 2 Agile methodology that was made to fit projects where agile principles bring the customer most value but that are not a simple project and needs to be controlled to a certain level. Our approach combines the best of the three worlds - Prince 2, Scrum and Design Thinking.
We focus on the teamwork in a self-organizing team, fast deployment and learning, less paperwork, focus on the product and other positives that Scrum bring to the table. We follow the Scrum rules on the delivery level - we have stand-ups every day and we have plannings, retrospectives and reviews.

Managers and other roles
The amount of work released in an iteration is decided by the team, the product owner and the project manager of the mobile app development. The team from our app development agency in London is responsible for the result and is given boundaries in which they can operate and therefore can stay motivated and involved in the project and the product.
Delivery team methodology
On the delivery level, we also use Design Thinking framework for working on the initiation stage of the project and whenever new functionality is designed or checked with the users. We want to be as transparent as possible.
That is why the client is invited to take a part in every planning and review that is taking place at the beginning and at the end of each sprint. On top of that, the client also has access to our system where he can observe the pace of work, issues, news and other information as if being a part of the project team.
