Discovery
We define the app’s purpose, users, core functionality and technical requirements. This is where we identify risks, edge cases and integration needs, and decide what must be built now versus what can wait.
Senior-led mobile app development focused on performance, adoption and long term value.
Apps built to solve real problems.

Building a mobile app is not about launching quickly or ticking off features. It’s about solving a specific business problem in a way users will actually adopt and keep using.
Most app projects fail because of early decisions: the wrong platform, unclear scope, poor integration planning or features built without understanding real user behaviour. In some cases, an app isn’t the right first step at all, and we will say that before anything is scoped or built.
As an app development agency in Birmingham, we help you avoid that. Our process starts with how the app supports your business, how users will interact with it and what needs to be built now versus later. That clarity shapes every design, technical and delivery decision.
The result is an app that is stable, scalable and commercially sound; built to grow with your business, not hold it back.
An app only succeeds if users understand it quickly, trust it and find it easy to use from the first interaction. Slow load times, confusing flows or unclear interfaces will kill adoption fast, regardless of how strong the underlying idea is.
For the business, these design decisions also have long term impact. How users move through the app, how interfaces are structured and how clearly actions are signposted all affect engagement, support overhead and future feature growth. These are not problems you want to uncover after launch.
Apps fail when users don’t understand what to do next. We design focused user journeys that remove friction, guide behaviour and make the app immediately usable, whether it’s customer-facing or internal.
Design only works if it survives development. Our designers and developers work side by side to ensure your app is built exactly as designed, with no compromises in layout, spacing or interaction.
Good mobile app design reflects real user behaviour. We prioritise speed, clarity and repeat usage, using engagement mechanics such as notifications or saved states only where they support the user journey.
“When we decided to redo our website, we called quite a number of web designers and were provided with numerous addresses of sites created by each designer. We found that ALT Agency had the most sites that we thought were innovative, creative and professional. After speaking a few times with ALT Agency we decided to go with them. It’s the best decision we’ve made in quite some time.
Joe Sapak“There are two important considerations when looking for a designer, work quality and reliability. Alt Agency offer both in spades.
Ben Stephenson“Craig is 100% on it and I mean on it, I can’t recommend him and ALT Agency highly enough.
Al Gosling“I found Craig & ALT Agency through the UKBF forums and I can honestly say its been a pleasure to work with Craig & his team. The end result is exactly what I wanted and more. The site is for my landscaping company with the aim of drumming up more business around our local area as well as somewhere to showcase our previous work to potential clients.

Native, hybrid or Progressive Web App (PWA) decisions should be driven by performance, cost and future plans, not developer preference. We recommend the approach that fits how your app needs to work today and how it needs to grow tomorrow.
Apps often fail when early technical shortcuts limit future features, users or integrations. We engineer clean, scalable architectures from day one so your app can grow without rebuilds, workarounds or platform lock-in.
Most apps don’t live in isolation. We integrate CRMs, payment gateways, booking systems, stock platforms and bespoke APIs so data flows reliably and securely as usage increases.
Your app is scoped, architected and delivered by senior developers. That means better technical decisions early on, fewer surprises during development and a stronger foundation for long-term support and iteration.
At ALT Agency, your app is designed, developed and supported entirely in-house. There is no outsourcing and no handover gaps. The people shaping the strategy are the same people writing the code. We have delivered apps across B2B, consumer and internal use cases, including platforms with complex workflows, integrations and compliance requirements.
Every app is led by senior, Birmingham-based developers from the outset. Your mobile app is scoped, architected and delivered without being passed through layers of juniors, reducing early mistakes and preventing avoidable issues later.
Design and development work side by side throughout the project. This ensures the app is built exactly as designed, with no visual compromises or unexpected behaviour changes.
We regularly build internal operations apps, customer portals, booking and payment apps, loyalty platforms and field-based data capture tools. Some mobile apps replace manual processes, others create new customer touchpoints. The structure depends on the problem being solved, not a predefined template.
We manage the full launch process, including testing, deployment and submission to the App Store and Google Play. After launch, we provide structured maintenance, updates and ongoing development to support long term growth.
App development projects fail when early decisions are rushed or left undefined. Our process is designed to remove uncertainty early and keep delivery focused on building something users will actually adopt.
You stay involved without needing to manage developers or translate requirements. We guide decisions, challenge assumptions and keep the project moving without unnecessary complexity or wasted effort.
Where appropriate, we start with a short prototype phase to validate user flows, confirm technical feasibility and tighten scope before full development. This reduces risk and prevents budget being spent on the wrong things.
We define the app’s purpose, users, core functionality and technical requirements. This is where we identify risks, edge cases and integration needs, and decide what must be built now versus what can wait.
User flows and interfaces are designed with adoption and usability in mind. You review fully interactive designs in Figma before development begins, so behaviour, layout and interactions are clear from the outset.
Mobile app development follows a fully scoped plan, led by senior developers and supported by in-house QA. Performance, stability and scalability are built in from day one, keeping delivery predictable and avoiding surprises at launch.
Clear journeys and intuitive interfaces make all the difference.
Our Birmingham-based app developers ensure every workflow, integration and interaction is designed for ease of use, engagement and retention. From native to PWA, we build apps that perform and scale.
Start Your ProjectWhat platforms do you develop apps for?
We develop native iOS apps using Swift, native Android apps using Kotlin and cross-platform apps, including Progressive Web Apps (PWAs). The platform is chosen based on performance needs, user behaviour, budget and long-term plans. We recommend what best supports your business goals, not what is quickest or easiest to build.
Should my app be native, hybrid or a Progressive Web App (PWA)?
There is no single “best” option in isolation. Native apps offer the highest performance and deepest device integration. Hybrid apps can reduce development time and cost while still delivering a strong user experience. PWAs can be effective when distribution, speed and accessibility matter more than app store presence. We help you choose based on how the app will be used, what it needs to integrate with and how you plan to scale.
Can my app integrate with our existing systems?
Yes. Most apps need to integrate with existing systems such as CRMs, payment gateways, booking platforms, stock systems or bespoke internal tools. We plan integrations upfront and handle them securely, ensuring data flows reliably between systems and avoiding manual workarounds or duplicated data after launch.
Will you sign an NDA?
Yes. We are happy to sign a non-disclosure agreement before any detailed discussions take place. Many of the apps we build involve sensitive commercial ideas or internal processes. Protecting that information is standard practice, not an exception.
How much does it cost to build an app?
Mobile app development costs vary depending on platform choice, complexity, integrations and feature scope. A simple internal tool is very different from a consumer-facing app with payments, accounts and automation.
We fully scope the app before development begins so you understand what’s included, what can be phased later and how budget is protected. No vague estimates and no mid-project surprises.
