Not sure which package is right for you? Let's Discuss Your App →
How much does it cost to build an app? −
Our fixed-price packages start from £4,999 for Launch and £9,999 for Scale. Complex apps, marketplaces and larger platforms receive a tailored quotation through our Command package. Your price is agreed before development begins.
How long does it take? +
Every app is different, so your timeline is agreed as part of your development plan before work starts. You'll see clear milestones and regular working builds throughout, so progress is never a mystery.
Do I own my app? +
Yes, completely. Your source code, designs and app store accounts belong to you, with full ownership of your intellectual property.
Where is my project managed? +
Your project is managed by a dedicated UK point of contact who coordinates the development team and keeps you informed at every stage. You never have to chase developers yourself.
I already have an app. Can you help? +
Yes. We'll review your existing app, then improve and develop it to help you move forward, whether that means fixes, new features or a fresh design.
What happens after my post-launch support ends? +
Every package includes post-launch support: 30 days for Launch, 60 days for Scale and an agreed period for Command. After that, your app, code and accounts stay fully yours, and we can quote ongoing maintenance or new features upfront so there are no surprises.
Do I need a fully developed app idea? +
No. Many clients come to us with just an early concept. Our Plan phase helps shape your idea into a clear development plan, with the right features for your first release, before any development begins.
Build. Launch. Grow.
