Yes.
You can change any content you want after your app has been through the approval process. You are always able to edit your app through the app dashboard and make whatever changes you like. When you are finished editing your app click the button at the bottom of the dashboard that says "Update Live App." That will instantly push your changes out to your app. If you want some changes made that you're not sure how to do on the dashboard yourself, feel free to contact your support representative or email us at support@e-zekiel.com.
Changing any of your app vitals (app name, loading images, description, keywords, etc) will require a resubmission of your app to Apple for approval, which costs a resubmission fee of $99. This is usually faster and easier than the first approval.
