"Shouldn't we have an app?" We get that question at least once a month. The answer is almost always: no.
An app costs SEK 100,000-500,000 to build properly. It needs maintenance, updates for every new iOS and Android version, and you have to convince people to install it. Most won't.
What you need instead: a mobile-friendly website. It works in every browser, on every phone, without anyone needing to download anything. And it costs a fraction.
The only small businesses that need an app are those offering a service people use daily (like Swish, not your hair salon) or those that need offline functionality (like a measurement app for tradespeople in the field).
If your customers book appointments, check prices or contact you: a good website does all of that. Save the money for something that actually gives a return.
