A Demo App is any app that you create that is not covered under a paid plan. Demo Apps have all the features of active apps but their install count is limited to 10.
During your free trial, any app you create is a Demo App until you subscribe to one of our plans. Once you've chosen a plan, any additional apps you create that aren't covered by your plan will be Demo Apps. For example, if you are a Multi subscriber and you've created 3 apps, the next app you create will be automatically deemed a Demo App.
