When a website is enough
If customers need to understand your services, browse your work, and contact you, a focused business website is usually a strong starting point. Keep the content clear, the navigation simple, and the next step obvious.
When an app makes sense
An application is useful when people need to sign in, manage records, track work, book resources, or interact with business data. Start by listing the actions users must complete, then group them into a focused first release.
Start with the workflow
Write down the current process and its biggest friction points. Decide what a successful result looks like. That gives you a better project brief than choosing a framework before defining the problem.
