Creating your app is a great step in advancing your digital profile; this doesn't mean you'll suddenly have all the app-users you ever dreamed of.
Like all things, this requires effort and communication - you need to let your customers know about your app, and give them reason to install it.
This is why we have a focus on purpose. If your app has a clear purpose for being on your customers' phones, then they will be able to buy-in to the benefit being created for them, your app will attract users, and your business will see the benefits too.
In your Dashboard you will see the 'Promote' section. This is where you can find the links to your app in the various app stores, as well as a template for emailing users with the app store links too.
Point is: Don't be shy. Tell everyone about your app and give them good reason to install your app!
