The Top 10 App Developers in London

London is a central node in the global tech network. The city thrives in areas like fintech, AI, and software development, and its large population and strong economy have positioned it as a leading hub for technology and startups.

London also has plenty of app development agencies, but it isn't always easy to choose the right ones.

Online directories are plagued by companies gaming the results and spoofing their locations, with many located nowhere near London. There are also some unreliable outfits that don't really offer the services they claim!

At MobiLoud we've built thousands of iOS and Android apps, and we've worked with plenty of app development agencies. We used our experience to research London app developers, and eventually came up with a list of the top 10!

You can use this list as a starting point, then research each option in more detail to make a decision. We'll also explain why, if you already have a website or web app, MobiLoud is a better option than any London  app developer.

Let's get started.

So there you have it, the 30 best app developers in London. Go ahead and contact them or do further research to make a decision.

Firstly though, one question.....Do you really need an agency?

As we've seen, there are plenty of app developers in London who can build decent apps.

They have their downsides though. For a start, they aren't cheap, and basic apps will likely set you back £50k+. They also tend to be busy with work, and even if they can start working on your apps right away - it'll most likely be 3-6 months to get a first version shipped (minimum).

This is all worth it, of course, to get great apps. But is it necessary?

No - not if you already have a website, online store, or web app.

MobiLoud: More Affordable (and Effective) than any App Developer

If you already have a working app for the web, you don't need an app development agency to build you iOS and Android apps from scratch.

You can save tens of thousands of dollars - and months of waiting - by using MobiLoud.

MobiLoud converts your existing website, online store, or web app into native mobile apps in just weeks, for a fraction of the cost of an agency. There's no long wait times, no six-figure invoices, and no need to compromise on your apps' features and functionalities.

MobiLoud apps:

  • Allow you to reuse everything from your website or web app (all features, plugins, integrations)
  • Blend the best of the web with the best of native app technology
  • Require minimum time and zero technical skill to manage

Compared to an app development agency - in London or elsewhere - using MobiLoud can easily save you 90% of the cost and months of effort.

We can build you any kind of app, so long as you have an existing website or web app to provide the content. We've built thousands of apps over the years, for:

  • Digital publishers like Foreign Policy, Simple Flying, and Deeper Blue
  • eCommerce brands like Rainbow Shops, Bestseller, and John Varvatos
  • Startups like Givi, RespiTrac, and Gear2Go

And pretty much any other vertical you can think of!

Our model is affordable and manageable for even small startup businesses, while remaining powerful and scalable enough for a global brand. Take a look at some of our app examples and case studies.

It doesn't matter whether you're located in London or anywhere else. Our global team are always just an email (or a call) away to support your business.
