An app is worth it when the same person comes back several times a week, or when push notifications are critical to the business. For occasional use a website is almost always the better choice.
Installing an app is a barrier. People cross it when the benefit repeats - banking, transport, delivery, a tool they work in. If the service is used twice a year, the app will not be installed. Or it will be installed and then deleted.
Everything else - accounts, payment, booking, even offline use - a modern website can do. A push notification is a direct channel to the screen. If you will not use push, or will use it rarely, you do not need the app’s main advantage.
The stores charge annually and change their rules regularly. An app left untouched for eighteen months often simply stops working. That is not an argument against apps. It is a cost that belongs in the budget from the beginning.
A website that works properly on a phone first. Then measure whether people come back, and how often. If the numbers say they do, you build the app on evidence instead of on a guess.
Start from "how often does the same person return". Rarely: website. Constantly, and you need push: app.
