What drives the price of an app
Six factors account for most of the difference between a £25k and a £150k app.
Platforms and devices
Whether you launch on iPhone, Android or both, and whether you support tablets, wearables or older devices.
Features and complexity
The number of screens, user roles and custom features is the biggest driver of cost.
Design
Using proven UI patterns costs less than a fully bespoke design system and animations.
Integrations
Payments, CRMs, booking systems and legacy software each add effort and testing.
Security and compliance
Regulated data (health, finance, children) needs extra security, audits and documentation.
Backend and admin
How much your management dashboard needs to do, from simple content updates to real-time reporting.

How much does it cost to build an app in London?
A focused native MVP typically costs £25,000 to £45,000, and a fully featured growth app £45,000 to £90,000. Complex, enterprise or regulated apps start from around £90,000. You get a fixed-scope quote after a free consultation.
Why do app development costs vary so much?
Cost is driven by the number of features and screens, the platforms and devices you need, design complexity, your backend and admin requirements, integrations and any security or compliance needs. A focused MVP keeps the first investment low.
Do I need both an iPhone and an Android app?
Not always. Many clients launch first on the platform their customers use most, prove the product, then build the second native app. We will help you decide based on your audience and budget.
Are there ongoing costs after launch?
Yes. Budget for hosting, app store fees and maintenance. Our support plans start from £1,250 per month and cover OS updates, monitoring, fixes and small improvements.
Do you offer fixed prices?
Yes. After discovery we agree a fixed scope and price, so you know exactly what you are paying for. Any new features are quoted separately before work starts.
How do payments work?
Projects are split into milestones, typically a deposit to start, then payments tied to agreed deliverables, with the final payment at launch.
