Why "How Much Does an App Cost?" Has No Single Answer
Ask three developers what an app costs and you will get three very different answers, because "an app" can mean a four-screen booking tool for a hair salon or a two-sided marketplace with payments, chat and an AI recommendation engine. There is no honest headline number, only a set of decisions that together decide the price — which is what this guide covers, along with the ongoing costs nobody mentions on the sales call and how to get a fixed-price quote you can trust.
What "An App" Actually Means — and Why It Changes the Price
There are three broad routes, and choosing between them is the biggest pricing decision you will make.
Native iOS and Android. Two separate codebases in Swift and Kotlin. Best performance and deepest device access, but you are effectively paying for two apps. In 2026 it is rarely the right choice for a UK SME unless the app is graphics-heavy or hardware-dependent.
Cross-platform (React Native or Flutter). One codebase that ships to both app stores. Both frameworks are current and actively maintained — React Native by Meta, Flutter by Google — and this is now the default route for business apps, because building one codebase instead of two meaningfully cuts cost, with performance more than good enough for booking, e-commerce and most AI-powered products. It is what we use for most projects at /services/mobile-app-development.
Progressive web app (PWA) or web app. A mobile-friendly web application that installs to the home screen but is not distributed through the app stores. Usually the fastest and cheapest route, and often right for internal tools and customer portals that do not need push notifications or store presence.
What Sits Behind Every Quote
A scope for a professionally built app includes a proper backend, testing and store submission, structured roughly like this:
| Scope | What it typically includes | What moves the price | Typical timeline |
|---|---|---|---|
| MVP app | One core user journey, iOS and Android from one codebase, basic accounts, analytics, store submission | Journey complexity, number of screens, data model | 6–10 weeks |
| Full product app | Accounts, payments, notifications, AI features, backend and admin panel, ongoing releases | Integrations, roles and permissions, design originality | 10–16 weeks |
| Enterprise app | Complex integrations, offline mode, security and compliance reviews, multi-region infrastructure, SLA support | Legacy systems, security review, scale | 16+ weeks |
| PWA or web app alternative | Installable web application with accounts and dashboards, no app store distribution | Same drivers as a full product, minus store submission | 6–10 weeks |
Where most UK businesses land
Most owner-managed businesses and early-stage startups sit in the MVP band, and the honest advice is usually to start there even if the vision is bigger. Founders with validated demand typically need the full product band. Enterprise-level scoping applies when the app must talk to legacy systems, work without signal, or pass a security review before procurement signs it off.

What Drives the Cost Up or Down
Two businesses asking for "a booking app" can receive wildly different quotes. These features explain most of the difference.
User accounts and roles. Simple email sign-up is quick. Social login, two-factor authentication and separate permission levels for customers, staff and admins each add design and testing time.
Payments. A card payment through Stripe is well trodden. Subscriptions, refunds, split payments for a marketplace, or in-app purchases through Apple and Google add complexity and compliance work.
Chat and messaging. Real-time chat needs infrastructure for delivery, notifications, moderation and history, and is one of the most underestimated features on any brief.
AI features. An AI assistant, document extraction, image recognition or personalised recommendations can add anywhere from a modest line item to a large share of the budget, depending on the accuracy and guardrails needed.
Offline mode. Apps that must work without signal (field engineers, site inspections, rural deliveries) need local storage and conflict resolution on reconnect — genuinely hard, and a major reason enterprise apps cost more.
Integrations. A CRM, accounting package, property portal or EPOS with a clean API is manageable. Systems with no API or poor documentation can add weeks.
Admin panel. Almost every app needs a back office to manage users, content, orders or bookings, and it is expensive to add once forgotten on the brief.
Design originality and compliance. A proven design system with your branding applied is efficient; fully bespoke animation costs real money. Health data, financial services, apps used by children, or anything handling identity documents brings extra requirements around UK GDPR, data residency and audit logging.
Hidden and Ongoing App Costs to Budget For
The build price is not the total cost of owning an app. Budget for the following from day one.
App Store and Google Play fees. Both Apple and Google charge a developer account fee, published on their own developer pages, though structured differently: Apple's is an annual membership, Google's a one-off registration covering the account for good. Both stores also take a commission on in-app digital purchases, with reduced rates under each store's small business or first-year terms; physical goods and services sold through your own payment provider are not subject to it.
Backend hosting and APIs. Servers, a database, file storage, push notifications, maps, SMS, email delivery and AI model usage all bill on usage, light for an MVP and meaningfully more for a busy product app under real load.
Maintenance and OS updates. A widely used industry rule of thumb, cited by analysts including Gartner, treats steady-state annual maintenance as a meaningful fraction of the original build cost, covering bug fixes, security patches and OS compatibility. Apple and Google change store rules and release major OS versions every year; apps that are not updated eventually break or get removed, which is why maintenance is not optional. The first year after launch often runs higher than steady state while the team stabilises the app against real-world usage.
UK Agency vs Freelancer vs Offshore: An Honest Comparison
Every business owner pricing an app considers the cheaper routes. Here is how they typically compare.
| Factor | UK agency | UK freelancer | Offshore team |
|---|---|---|---|
| What moves the price | Team size, design originality, integrations | One person's day rate and availability | Headline day rate, but rework is common |
| Communication | Same time zone, in-person meetings, one project lead | Direct and fast, but one person's availability | Time zone and language gaps; more of your time spent managing |
| IP and contracts | UK contract, IP assigned to you, enforceable under English law | Fine with a written contract and IP assignment | Enforcing IP or contract terms across borders is difficult |
| Quality risk | Team covers design, development, testing and PM | Depends on one individual's availability | Wide variation; rework often erases the headline saving |
| UK GDPR | Familiar with UK data protection | Varies with experience | Data may be processed outside the UK, which must be assessed |
The cheapest headline quote is often not the cheapest project. A founder who pays a low rate offshore and receives something that cannot be shipped ends up paying a UK team to rebuild it. Compare the total cost of getting a working, maintainable app into customers' hands, not day rates in isolation.
How to Cut App Development Cost Without Cutting Corners
- •Build an MVP first. Ship the one journey that proves customers will pay, then fund the rest from revenue or investment. Our MVP service at /services/mvp-development is built around this.
- •Choose a PWA where the store is not needed. If your users are staff, members or existing customers, a web app they install to their home screen may do the job for a fraction of the price.
- •Reuse proven platforms. Authentication, payments, notifications, analytics and AI models all have mature services. Paying to reinvent them is waste.
- •Phase features. Put chat, loyalty, referrals and reporting on a roadmap rather than in the first release.
How a Fixed-Price App Quote Is Produced
A credible fixed price comes out of a short process, not the first phone call.
- 1. Discovery call. A short conversation about your business, your users, what the app must do on day one and what can wait.
- 2. Scoping. A written list of features and screens, what is in and out of the first release, and flagged risks such as awkward integrations.
- 3. Technical decisions. Native, cross-platform or PWA; which backend and third-party services; where data lives.
- 4. Estimate and buffer. Each feature is estimated for design, development and testing, with a contingency for the unknowns every real project has.
- 5. Written proposal. A single fixed price, a timeline with milestones, what is included, and what a scope change would cost.
Anything less is a guess dressed up as a quote.
Questions to Ask Before You Hire an App Developer
- •Can I see two apps you have built that are live in the App Store or on Google Play today?
- •Will I own the source code and all intellectual property when I have paid, and is that in the contract?
- •Is the price fixed, and what happens if I ask for a change mid-project?
- •Who will I speak to each week, and are they in the UK?
- •What is included after launch, and what does maintenance typically cover in the first year?
- •Where will user data be stored, and how do you handle UK GDPR?
How BigBerri Approaches App Development Cost
We are a Manchester AI development company building mobile apps, web apps and MVPs for UK businesses. Our approach is deliberately simple.
- •Free discovery call. We tell you honestly which route makes sense, including when a PWA or a lean MVP would serve you better than the app you first described.
- •Fixed price after discovery. A written scope and a single price. If the scope does not change, the price does not change.
- •AI built in from day one. Because we build our own AI products, assistants, smart search and document extraction are part of how we design an app, not an afterthought.
- •UK data handling. Data residency, retention and deletion are agreed in the proposal, not retrofitted.
Sector matters too, which is why we publish industry pages such as /industries/estate-agents.
The Honest Answer on App Cost
For a UK business in 2026, the real range runs from a lean MVP on iOS and Android, through a full product with payments, AI features and an admin panel, to an enterprise-grade build with legacy integrations and a security review. A web app or PWA can bring the first release down considerably, and every route needs an ongoing allowance for maintenance, hosting, store fees and third-party services.
The fastest way to turn that into a real number is to talk it through. Book a free discovery call at /contact for a straight answer on cost and timeline.
Frequently Asked Questions
How much does it cost to build an app in the UK in 2026?
There is no fixed figure, because the price depends on scope: an MVP with one core journey, a full product with payments and AI features, and an enterprise build with legacy integrations and a security review sit at very different price points, and a PWA or web app alternative is usually the cheapest route to a first release. Book a free discovery call at /contact for a fixed price once we know what your app needs to do.
How long does it take to build an app?
An MVP app typically takes six to ten weeks, a full product app ten to sixteen weeks, and an enterprise app sixteen weeks or more. BigBerri targets a fast turnaround for most MVP first releases once the scope is fixed.
What are the ongoing costs of running an app?
Budget for App Store and Google Play developer account fees (structured differently by each store but published on their own developer pages), backend hosting that scales with usage, usage-billed third-party APIs, and maintenance for bug fixes, security patches and OS updates, which a widely used industry rule of thumb ties to a share of the original build cost per year.
Is it cheaper to build a cross-platform app than native iOS and Android apps?
Usually, yes. Building once in React Native or Flutter and shipping to both stores meaningfully cuts cost compared with two separate native codebases, and is the right choice for most UK business apps.
Should I use a UK agency, a freelancer or an offshore team?
Offshore and freelance routes often have lower headline rates, but carry higher risk around communication, IP enforcement, quality and UK GDPR. A UK agency usually costs more upfront but delivers a shippable, maintainable app with a single accountable contact. Compare total cost to launch, not day rates.
