Frequently asked questions
How much does it cost to develop a mobile app in London?
Most projects we deliver range from £8,000 for a focused MVP to £60,000+ for a complex, enterprise-grade app. After a free discovery call we provide a fixed, transparent quote with no hidden fees.
How long does it take to build an app?
A typical MVP launches in 8–12 weeks, while larger products take 4–6 months. We work in agile sprints so you see progress every two weeks and can launch sooner with a phased rollout.
Do you build for both iOS and Android?
Yes. We build native iOS (Swift) and Android (Kotlin) apps, as well as cross-platform apps with React Native and Flutter so you can reach both platforms from a single codebase.
Will you maintain the app after launch?
Absolutely. We offer ongoing maintenance, monitoring, analytics and feature iteration plans to keep your app secure, fast and ranking well in the stores.
Do you work with startups as well as enterprises?
We do. We partner with early-stage founders raising their first round right through to established enterprises modernising their mobile presence across London and the UK.
