How to Build an iOS and Android App for Your Online Store

Why a Mobile App Increases E-commerce Sales

Creating an iOS and Android app for your online store improves user experience, increases retention and drives more repeat sales. Unlike a browser, an app is always present on the customer’s device, making access and interaction with the brand easier.

In a context where most traffic is mobile, having an app is no longer just an advantage. It becomes a competitive factor.

Difference Between Mobile Website and Mobile App

A responsive online store is essential, but it does not replace an app.

Key Differences

  • Apps enable push notifications.
  • Apps provide direct access from the user’s home screen.
  • Higher performance compared to browsers.
  • More fluid and personalised experience.

A complete mobile strategy combines both channels.

When It Makes Sense to Build an App
