Mobile App Development Company in London

Next Olive is a mobile app development company working with businesses in London and the UK since 2011. You get senior engineers on mobile apps, a project manager who overlaps your working day, GBP or USD invoicing — and typically 40–60% lower cost than a local agency for the same senior team. London is Europe's largest fintech and insurtech cluster, with a strong proptech, health-tech and marketplace scene. UK buyers expect UK GDPR-compliant data handling, FCA-aware design for anything touching payments or lending, and NHS DTAC alignment for clinical products.

What we deliver

• Native iOS (Swift) and Android (Kotlin) apps
• Flutter and React Native cross-platform builds
• UX/UI design with local-market research
• Secure backend APIs, cloud hosting and analytics
• Payments, maps, push and third-party integrations
• App Store and Google Play launch and ASO

Why Next Olive

• Working hours that fit London: a 4.5-hour offset (5.5 in winter) — the whole UK morning overlaps with our afternoon.
• Contracts and invoicing the way UK companies expect — GBP or USD invoicing, mutual NDA, IP assignment on payment.
• Built for local rules: UK GDPR and the Data Protection Act 2018, FCA Consumer Duty and PSD2/Open Banking for finance, NHS DTAC and DCB0129 for clinical software, Cyber Essentials.
• Proof, not promises: UK clients from London to Manchester, 2000+ products delivered and 100+ engineers you can meet before you sign.

Mobile App Development use cases we deliver in London

These are the mobile apps our UK clients ask for most. Each comes with proven modules we reuse — which is why a first release usually ships in 8–14 weeks.

• On-demand service and delivery apps
• Retail and loyalty apps
• Booking and reservation apps
• Employee and field-service apps
• Community and membership apps
• MVPs for funded startups

Why UK businesses choose an offshore partner for mobile app development

Local senior developers in London are scarce and expensive, and freelancers rarely scale. A dedicated Next Olive squad gives you a full team — engineers, designer, QA and PM — at a monthly cost close to one local senior hire, with a 4.5-hour offset (5.5 in winter) — the whole UK morning overlaps with our afternoon.

You keep control: weekly demos on a staging build, a shared backlog you re-prioritise, and source code in your own repositories from the first sprint.

How we run mobile app development projects for London

Free consultation → short paid discovery (workshops, prototype, technical plan, fixed-price proposal) → two-week sprints with demos → launch and hand-over → optional support retainer or dedicated team. Change requests are agreed in writing before work starts, so the budget you approve is the budget you pay.

Our delivery process

1. Discovery: We map goals, users, integrations, and success metrics in a focused workshop.
2. Architecture: Solution design, milestone plan, and transparent estimate with clear assumptions.
3. Design: UX flows and prototypes validate the experience before full build.
4. Agile delivery: Two-week sprints with staging demos and visible backlog progress.
5. QA & launch: Testing, UAT, production deployment, documentation, and optional SLA support.
