How Much Does Mobile App Development Cost? (London)

London boutique retainers often dwarf Duyuz floors. Anchoring SEO Growth €399/mo and Business web €990–€1690 reframes cost without pretending to be a Soho walk-in studio. Duyuz mobile app work is discovery-led. Many MVPs land in a ballpark from about €8,000 depending on platforms, features and integrations — with written scope after we know the job-to-be-done. Native store apps, complex backends or realtime features cost more than a focused PWA.

Direct answer

What should you budget?

Treat ~€8,000 as a published starting conversation for scoped MVP work — not a blind fixed bid. Platform choice (PWA vs store apps), features and APIs determine the real number.

Ranges

Basic, intermediate and advanced scopes

Basic / PWA-first

Often below full native MVP

When mobile web or PWA meets the need — scoped after discovery.

Intermediate MVP

From ~€8,000

Core flows, one primary platform path, essential integrations.

Advanced product

Custom

Multi-platform native, complex backend, realtime, offline sync, or heavy compliance.

Typical project scope

Discovery, UX for core flows, build on an agreed stack, analytics events, and launch readiness (store consulting when applicable).

FAQ

How much does it cost to build an app in 2026?

It varies widely. Duyuz uses discovery to bound MVP cost; many focused MVPs start in conversation around €8,000+, while complex products are custom.

Do I need a native app?

Not always. We recommend native when store distribution or device capabilities truly matter.

How long is an MVP?

Often roughly 8–16+ weeks after discovery, written in the proposal.

Fixed price or time and materials?

We prefer fixed scope for MVP boundaries; open-ended product discovery is quoted differently.

Do you have a London office?

Delivery is remote. You get written scope and the same EUR floors — not a fake local address.

Is London Local SEO different?

Yes — competition density is higher; package level should match borough footprint and review strength.
