The instinct to build a mobile app has become almost reflexive among ambitious companies. Apps feel premium, serious, committed. Websites feel like something you launch before you're "real."
This instinct costs a lot of money. A native mobile app typically costs 3–4× more than an equivalent web experience, takes longer to ship, requires App Store approval, and — critically — demands that your users actively decide to download and install something before they experience any value.
That's a high bar. And for many businesses, it's the wrong bar to start with.
The real comparison
| Factor | Mobile App | Website / PWA |
|---|---|---|
| Time to market | 3–6 months (native) | 6–12 weeks |
| Typical cost | €40k–€200k+ | €12k–€60k |
| Distribution friction | App Store install required | Click a link, instant access |
| Discovery | App Store SEO + paid ads | Google SEO, social, referral |
| Updates | Submit → review → release | Deploy instantly, no approval |
| Push notifications | Native, high opt-in rates | Web push (lower opt-in) |
| Offline capability | Full offline support | Limited (PWA service workers) |
| Device hardware access | Camera, GPS, biometrics, etc. | Camera, GPS (browser APIs) |
| Ongoing maintenance | iOS + Android updates, OS changes | One codebase, simpler updates |
When you genuinely need a native app
Build a native app when:
Your core experience requires deep device integration (camera-heavy workflows, continuous GPS tracking, biometric authentication, AR features). Or when high-frequency daily usage makes app convenience genuinely valuable — and your users are proven to install apps in your category. Or when offline functionality is non-negotiable for your use case.
Food delivery, fitness tracking, payments, maps — these categories make sense as apps because users use them multiple times per day and benefit from notifications, offline mode, and hardware access.
When a website is the right starting point
Start with web when:
You're validating demand, onboarding a B2B user base, or building something people access weekly rather than daily. The web gives you faster iteration cycles, zero install friction, and SEO-driven discovery. You can always layer a mobile app on top once you've proven the model.
Most B2B tools, marketplaces, booking systems, dashboards, and e-commerce platforms are better served by an excellent responsive web experience than a native app — at least in the first phase.
The hybrid path: Progressive Web Apps
PWAs give you a middle ground: web technology that can be "installed" to a home screen, supports push notifications, and can work offline. For many use cases — especially B2C services with medium-frequency usage — this is the right answer. Faster to build, no App Store, but a more app-like experience than a plain website.
Don't choose between app and website based on what feels ambitious. Choose based on where your users are, how often they'll use it, and what the product experience actually requires.
We've seen companies spend six months and €80,000 building a native app that their users open once a week and could have served perfectly well as a mobile-responsive web dashboard. The lesson: validate on web, graduate to native when usage patterns justify it.
