App Development in London
We deliver production mobile apps end-to-end: architecture, design, native development, backend integration, paywall, push notifications and store release. Multi-tenant Supabase backends, Stripe subscriptions, offline-first sync, and a Play Console / App Store release pipeline that runs through GitHub Actions.
Why London businesses pick BozApps for mobile apps
BozApps works with London-based businesses across fintech, property, hospitality and consumer SaaS. We're a remote-first studio with regular in-person meetings in Central London, and the kind of fixed-price engagement model London founders prefer over the open-ended day rates that dominate the rest of the market.

Questions London businesses ask us
Straight answers, real numbers. Anything else — ask on a 30-minute call and you'll have a written proposal within five working days.
How much does app development cost in London?
Most full mobile apps run from £15,000 to £60,000 depending on scope, built over 8 to 14 weeks. We scope the smallest launchable version first and agree a fixed price up front after a 30-minute call, so you decide with a real number in front of you.
Do you build native Android or cross-platform apps?
Both. Native Android in Kotlin and Jetpack Compose where performance and platform features matter, or React Native and Expo when one codebase for Android and iOS fits better. We recommend the cheaper route that still fits your product, and explain why in the proposal.
Do you work with London businesses remotely?
Yes — we're a remote-first UK studio working with clients across Greater London and the rest of the UK. You watch progress on a private preview link with weekly demos, and we're happy to meet in person when it helps.
Who owns the app and the code?
You do. The code lives in a repository you own, the store listings and backend accounts are registered to your business, and you can walk away with everything at any point.
What happens after launch?
We can hand the app over, or keep operating it on a monthly retainer covering hosting, monitoring, security patching and a feature increment each month. Retainers start at £20/month.
