Mobile App Development Company in London

We work with London clients through one named lead who is your point of contact from kickoff to handover, backed by the same engineering team on every project.

Usually cross-platform, with native modules where a feature demands it. London users skew towards recent iPhones and flagship Android devices, so polish, accessibility and platform conventions matter more than squeezing the app onto low-end hardware. We ship both platforms from one codebase and integrate what local users expect — typically Stripe and GoCardless; Open Banking APIs; and Xero and Sage.

A focused first release — one core journey on iOS and Android, with login, analytics and store submission — usually takes eight to twelve weeks. Apps with payments, offline sync or hardware integrations take longer. We scope in a short discovery phase and give you a fixed plan for the first release before you commit.

Most often Fintech, Insurance, Professional Services and Media & Entertainment, because that is where London's economy is concentrated. We are not limited to those sectors — the engineering transfers — but that is where we can bring the most relevant experience to a first conversation.

Most London projects touch Stripe and GoCardless; Open Banking APIs; Xero and Sage; and Apple Pay and Google Pay. We integrate with what your customers and staff already use, and we check API access and commercial terms for each before committing to a timeline.

Cross-platform with React Native covers the majority of business apps at roughly half the cost of two native codebases. Go native when you depend heavily on platform-specific hardware, sustained high-performance graphics, or deep OS integration. We make the call against your feature list and tell you which applies.

A focused first version with one strong core loop is typically three to four months including store release. Apps with payments, real-time features or complex offline sync take longer, and we scope those explicitly rather than discovering them mid-build.

Yes, including listing assets, privacy declarations, signing and phased rollout. First submissions are frequently rejected on guideline details, so we prepare for review requirements during the build rather than after.

Yes, and for most apps it should. We design a local data layer with sync and conflict handling, so the app stays usable without connectivity and reconciles cleanly when it returns.

Usually yes. If your web platform already has a solid API we build the app against it, sometimes adding mobile-specific endpoints to reduce round trips and payload size on slow networks.

Mobile requires ongoing attention: OS updates, store policy changes and crash fixes. We offer a maintenance arrangement, and we hand over signing credentials and documentation so you are never locked in.
