So, you’ve got an idea. A “what if…” moment that keeps circling back. You know it could make a difference - whether it’s transforming how your team works, creating a smoother customer experience, or launching a new revenue stream altogether.

Now what?

App development can feel like a bit of a black box - especially if you've never done it before. But at The Distance, we believe in transparency. Whether you're a travel business going paperless or a healthcare provider streamlining operations, you deserve to know what’s happening behind the scenes.

This guide breaks down the full journey - start to finish - with zero jargon, lots of honesty, and a sprinkle of insight from our team of experts who’ve helped launch apps for businesses across the UK and beyond.

 

Step 1: Discovery & strategy

The “What are we actually building?” phase

Before anyone starts sketching screens or writing code, we ask the big questions:

  • Who is this app for?
  • What problem are we solving?
  • What does success look like?

This is where we dig deep. Expect workshops, conversations, and collaborative whiteboard moments (virtual or IRL). We're not just asking about features - we're unearthing your pain points, your audience’s behaviours, your business goals, and your future plans.

🧠 Stat to know: 42% of startups fail because there’s no market need for their product. That’s why discovery is everything.

We use this phase to define a high-level user journey that aligns with what your users actually need - and what your business can realistically deliver. This is about focusing on the core experience and ensuring we understand the key steps users will take in your app. You’ll walk away with a clear sense of direction and a solid understanding of how we’re going to guide users through their journey.

At the same time, we also start exploring the technical landscape - looking at systems architecture, integrations, and any third-party platforms your app will need to connect with. Every project is different, so we’ll work closely with you to understand your current setup and advise on how we’ll approach the technical side of the build. Whether it’s designing something from scratch or slotting into existing systems, we make sure it’s all mapped out early on.

 

Step 2: UX & UI design

Where ideas take shape

This is the fun bit - where we start turning strategy into something visual.

First up, UX (User Experience). We map out user journeys, wireframes, and navigation flows to make sure the app is intuitive, seamless, and actually usable. Then comes UI (User Interface) design - where your brand and personality come to life through colour, typography, and visual storytelling.

We don’t design in a vacuum. Every decision is tested, iterated, and reviewed with your users in mind. This is where we make sure that your app won’t just look good - it’ll feel good to use.

🎨 Design matters: 94% of first impressions are design-related. Don’t leave this to chance.

Step 3: Development

This is where the magic (and code) happens

With a solid plan and approved designs in place, our developers get to work. We typically use React Native, a framework that lets us build high-quality apps for both iOS and Android from a single codebase - saving you time and budget without compromising on performance.

Our developers are problem-solvers. Behind every swipe, scroll, and tap is a logic puzzle being solved. Whether it’s integrating a booking system, syncing with your internal CRM, or handling payments securely - we’ve seen it, built it, and optimised it.

We work in sprints, meaning you’ll get regular updates and see progress in real time. No disappearing into the dev cave for six months. You’ll be involved, informed, and invited to give feedback along the way.

⏱️ Speed counts: 70% of users abandon apps that take too long to load. Performance isn’t optional - it’s essential.
 

Step 4: Testing

Because nothing kills a great app faster than a bad bug

Once your app is built, we stress-test the hell out of it.

We test across devices, operating systems, and screen sizes. We check how it performs on patchy Wi-Fi, low battery, and under pressure. We simulate real user behaviour and edge cases you may never have considered (like, what happens if someone presses "back" 17 times in a row?).

Our QA team works alongside our developers to squash bugs, ensure security, and polish performance until everything just works.

🐞 Cost of skipping QA: Fixing a bug after launch can cost 6x more than fixing it during development.

Step 5: Launch

It’s go time.

With testing complete and your sign-off secured, we prep your app for launch. That means submitting it to the App Store and Google Play, meeting all the necessary compliance requirements, and navigating the (sometimes frustrating) review processes on your behalf.

We’ll also help with rollout strategy. Do you want a soft launch for internal teams first? Are you coordinating a marketing push? Want to monitor user uptake before scaling? We’ll work with you to plan the right approach.

And then… it’s live.

There’s nothing quite like seeing your app in the wild - used by real people, doing what it was designed to do.

 

Step 6: Post-launch & ongoing support

Because launching is just the beginning

Successful apps aren’t built once and left to gather dust. They evolve. Post-launch, we track usage data, gather feedback, and help you prioritise new features or refinements. Whether it’s performance updates, user feedback loops, or keeping up with OS changes, we’re here for the long haul.

📈 Retention reality: 25% of users abandon an app after just one use. The post-launch experience is just as important as the launch itself.

We offer ongoing support and maintenance packages that keep your app healthy, relevant, and performing at its best - so you can focus on the bigger picture.

 

So, what should you expect when working with an app agency like us?

  • A clear and collaborative process
  • Regular communication and honest feedback
  • Deep thinking, not just box-ticking
  • A team that cares about your users as much as you do
  • And most importantly, an app that delivers real results
 

Final thoughts

Building an app isn’t just about tech - it’s about vision, teamwork, and trust. Whether you’re brand new to the process or just need a partner who can go the distance, we’re here to guide you every step of the way.
