Website or app? Start with your customer.
Choose according to how people will use your service, rather than which technology is fashionable.

When a website is enough
For presenting services and work, receiving enquiries or offering an experience directly through a link, a website is often a useful starting point.
When to consider an app
Consider an app for repeated use or deeper access to device features. Also assess whether people will install it and what ongoing maintenance requires.
What about a platform?
A platform supports processes such as requests, permissions, accounts, data and dashboards. It can run in the browser or work alongside an app, depending on the scope.
Test the idea before expanding
Define the core function that offers value, then test it. Divide the work into stages so later decisions are based on real use.
