Website vs app is a question business owners ask because an app sounds like the more serious product, and the honest answer for almost every small business is that the website comes first and the app rarely comes at all. A website is found by anyone searching for what you do and works on every device without an install. An app has to be found in a store, installed, kept updated, and built twice for the two phone platforms under review rules the business does not control. This page sets out what each is for, what each costs to build and to keep running, and the narrow set of cases where an app earns its place alongside the site.
What a website does that an app cannot
It is found. A customer searching for a plumber in their town, a dentist taking new patients or a gym with a morning class finds a website, not an app, and can act on it in the same minute without installing anything. It works on every phone, tablet and desktop from one build. It can be changed this afternoon without a store review. And it is the thing every other channel, from a review site to a social profile to a printed leaflet, links to. A business without a website is invisible to the customer who does not already know it; a business without an app is not.
What an app does that a website cannot, and what it costs
An app sits on the customer's phone with an icon, can send notifications, can work offline and can use the phone's hardware. Those are real advantages for a business whose customers use it weekly: a gym with class bookings, a coffee shop with a loyalty scheme, a delivery service. The cost is that it is built for two platforms, submitted to two stores under their review guidelines, updated every time a platform changes, and installed only by customers who already know the business. On the website cost calculator, an app is a feature line several times the size of the site and a monthly maintenance line that never ends.
When an app earns its keep, and the middle road
An app pays for itself when existing customers use the business often enough that the install is worth their while and the notifications bring them back: repeat bookings, orders, loyalty. It does not pay for itself as a way of finding new customers, because they are not looking in the store. The middle road is a website built so it can be added to a phone's home screen and work offline, which gives most of the app's convenience from the site's single build. For most small businesses that is where the question ends.
Questions people ask about website vs app
Does having an app help us rank in search?
No. Search engines rank web pages. An app's store listing can appear in some results, but the business's findability comes from its website.
What does an app cost to maintain?
Two platforms' worth of updates whenever the operating systems change, plus store review each time, plus the servers behind it. The maintenance line is the reason many small business apps are abandoned within two years.
Can our website be made to feel like an app?
Largely, yes. A site built to modern standards can be added to the home screen, open full-screen, work offline for some functions and load fast. That covers most of what customers mean when they ask for an app.
