Every few months, a business owner asks us: "Should we build an app?" Sometimes the answer is a clear yes. Often, the honest answer is "not yet." Here's how we think through it.
When a Mobile App Makes Sense
Your Users Need It on Their Phone Regularly
Apps make sense when users need to access your service frequently — daily or multiple times a week. A gym, a food delivery service, a project management tool, or a loyalty programme all benefit from an app because users return regularly and value the convenience of a native experience.
If your users interact with you monthly or less, a well-optimised website is almost always sufficient.
You Need Device Features a Website Can't Access
Mobile apps can access GPS, push notifications, camera, contacts, biometrics, and offline storage in ways that websites can't (or can only partially). If your service relies heavily on location, real-time alerts, or offline functionality, an app is likely the right call.
Retention is a Core Business Metric
Subscription businesses, marketplaces, and communities that need to keep users coming back benefit enormously from push notifications and the psychological effect of having an icon on the home screen. App users typically have 3–4x higher retention than web-only users in the same product.
You Have an Existing, Validated Web Product
The best time to build an app is after you've validated your business model with a website. You know who your users are, what they need, and how they behave. Building an app first — before any web presence — is almost always a mistake.
When You Probably Don't Need an App (Yet)
Your Website Isn't Optimised for Mobile
If your website doesn't already work well on mobile, build a great mobile web experience first. A Progressive Web App (PWA) can deliver much of the app experience — offline access, add to home screen, push notifications — for a fraction of the cost of a native app.
You're Still Finding Product-Market Fit
Apps are expensive to build and even more expensive to maintain. If you're still iterating on your core product, the flexibility of a web product is a significant advantage. Build the app once you know exactly what you're building.
Your Users Only Come to You Occasionally
A local restaurant, a law firm, an estate agent — users don't need an app. They need a website that's fast, informative, and easy to contact. An app would sit unused on their phone and eventually get deleted.
Native vs Cross-Platform: A Quick Note
If you do decide to build an app, you'll face another choice: native (Objective-C/Swift for iOS, Kotlin/Java for Android) or cross-platform (React Native, Flutter).
For most businesses, React Native is the right answer. One codebase that runs on both platforms, 90%+ shared code, near-native performance, and significantly lower development and maintenance costs. We build all our client apps in React Native unless there's a specific reason to go native.
The Questions to Ask Yourself
- Do my users interact with my service at least weekly?
- Do I need device features (GPS, push, offline, camera)?
- Have I validated my product with a web version?
- Do I have a budget for ongoing maintenance (typically £150–500/mo)?
- Will an app meaningfully improve my retention or conversion?
If you can answer yes to three or more of these, a mobile app is worth serious consideration. If fewer, focus on your website first.
What to Do Next
If you're leaning towards building an app, the best first step is talking to someone who builds them regularly. We can usually tell you within 30 minutes whether an app makes sense for your situation, what the right approach would be, and a realistic cost.
