Do I need a mobile app, or is a responsive website enough? — answered by Engineer Saeed Baatiah
A responsive website is enough when customer contact is occasional — buying or enquiring a few times a year. An app is justified when use recurs at least weekly, or when you need device capabilities such as the camera, notifications, or offline operation. The middle option that saves a great deal: a progressive web app that installs to the home screen and sends notifications without the cost of building two native versions and shipping them to stores.
