First, the question every business should ask
Before investing in a mobile app, every business needs to answer one question: does this need to be an app, or could a mobile-friendly website do the same job?
Most of the time, a properly-built responsive website is sufficient. Apps make sense when the experience genuinely benefits from being native — offline access, push notifications, device hardware integration, frequent repeat use, or fast speed-of-interaction that browser-based experiences can't quite match.
If your honest answer is "a website would work fine", save your budget and build a great website instead. If you genuinely need the things only an app can offer, read on.
Five business cases where apps genuinely earn their keep
Across our mobile app development projects for UK businesses, five patterns recur:
- Loyalty and engagement — restaurants, salons, gyms, and retail businesses use apps to drive repeat visits with stamp cards, push offers, and easy booking.
- Field workforce tools — tradespeople, surveyors, engineers, and inspectors needing offline-capable forms, photo capture, and real-time syncing.
- Customer self-service — account management, billing, support tickets, and document access for B2B service businesses.
- Marketplace and booking — two-sided platforms where customers and providers transact, particularly when convenience drives repeat use.
- Health, fitness, and tracking — anywhere users log data daily and benefit from native device features like notifications and biometrics.
Native, hybrid, or progressive web app?
Once you've established the case for an app, the next decision is technical: which kind?
Native (Swift / Kotlin)
Best performance, full access to device features, separate codebases for iOS and Android. Higher cost but superior experience — the right choice when the user experience is the product.
Cross-platform (React Native / Flutter)
One codebase, both platforms. Almost-native performance for most use cases. The pragmatic middle ground we recommend for around 70% of business apps — great UX, sensible cost.
Progressive Web App (PWA)
A website that behaves like an app — installable, works offline, sends notifications. Cheapest option, no app store hoops, but limited device feature access. Often the smart starting point if you're unsure whether you need a full app.
What does a business app cost?
Realistic ranges for Suffolk businesses:
- Simple PWA — £6,000 to £15,000
- Cross-platform MVP — £15,000 to £35,000
- Full cross-platform v1 — £35,000 to £75,000
- Native, multi-feature platform — £75,000+
The hidden costs people forget
The build is just the first cost. Real-world app ownership also involves:
- App Store fees — Apple Developer Program (£79/year), Google Play (one-off £20).
- Backend hosting — servers, databases, push notification services, analytics. Typically £50-£500/month.
- OS update compatibility — Apple and Google release new OS versions annually, often requiring app updates to stay compatible.
- Ongoing development — users expect new features over time. Apps that don't get updated lose users.
How to know if your business is ready
Three readiness signals:
- You have an existing customer base who would actually download and use the app — building an app to attract first-time users is rarely cost-effective.
- You have a clear, measurable goal for what the app should achieve — more bookings, fewer support tickets, faster field operations.
- You have a budget for both the build and 18-24 months of ongoing improvements. Apps that don't evolve fail.
